Nissin Digital Flash FAQs

Here are some answers to frequently asked questions (FAQs) about Nissin Digital Flashes and accessories.

Nissin Air 1 Commander

Q:  Are Nissin Air 1 and Air 10s Commanders cross compatible with Nissin flash models for different camera platforms?  For example, will the Air 1 Commander Sony control an off-camera Nissin Di700A Nikon flash?

A:  The Nissin Air 1 and Air 10s Commander provide full control of NAS enabled off-camera Nissin flashes (Di700A, i60A, MG80, MG10), even those Nissin flashes made for different camera platforms.

Nissin flash models without the built-in NAS wireless technology (i400, i40, and i600) cannot be used with the Air 1 and Air 10s Commanders. However, the Nissin i40 and i600 can be used off-camera in the SD of SF optical slave mode.

Q:  Will the Nissin Air 1 Commander pair with the i60A if they are on different channels, or different groups (A,B, or C)?

A:  Yes, they will pair successfully, but they will not otherwise communicate to control the flash.  If the commander and flashes are paired but not firing confirm that they are on the same channel, and the same group.

For convenience, when pairing the i60A with a Nissin commander we recommend setting the flash channel to "A" (auto). 

Q:  Will the Nissin Air 1 Commander stay paired with my Nissin flash after one or both devices are turned off? 

A:  The Air 1 Commander and Nissin flash will maintain their pairing after the devices are turned off.  Removing the batteries will also not affect the pairing.

Q:  How do I turn Group A, B, or C on/off on the Nissin Air 1 Commander?

A:  Press the set button until the desired group light begins to blink; then quickly press the on/off button to turn the group on/off.

Q:  How do I change the zoom setting on a remote flash with the Nissin Air 1 Commander?

A:  To change the zoom setting on your remote flashes with the Nissin Air 1 Commander:  

1)  Press the "Mode" button on the Air 1 until "Z" and "24 35 50 70 85 105 135 200" appears across the bottom of the display.

2)  Press the "S" button to select the flash's group (A, B, or C) that you want to adjust.

3)  Rotate the selector dial to manually adjust the desired group's zoom setting (manual zoom only).

Q:  Group A, B, or C is missing from the Nissin Air 1 Commander screen.  When the group disappears I cannot control the flash.

A: The ability to turn a selected group off/on can be useful when shooting with multiple flashes in different groups, for example a 3-light portrait set-up using a main, background, and hair light.

If you do not see Group A, B, or C on your Air 1 Commander, and you did not deliberately turn off the group, then it was most likely turned off by mistake.

To activate/deactivate a group on the Air 1 Commander simply press the Set button until the desired group is active (blinking), then quickly press the on/off button.

Q:  What is the best channel to use when pairing the Nissin Air 1 Commander with my Nissin flash or Air R Receiver?

A:  When pairing, it is best to use the Auto Channel mode.

Q:  My Nissin Air 1 Commander and flash are paired, and the flash will fire when I press the pilot button.  However, when I place the Air 1 Commander on-camera the flash will not fire when I take a picture.

A:  Confirm that your Nissin Air 1 Commander is properly seated in the camera's hot shoe.  Gently push the Air Commander all the way forward until you hear a "Click" sound.

For Sony Users, the Air 1 Commander must be in the camera's hot shoe AND "WL" must be selected in the camera's flash menu.  If the "WL" mode is not selected in the camera menu the remote flash will not fire.

Q:  My Nissin Air 1 Commander is paired to a Nissin i60A, but the flash will not fire.

A:  The Nissin i60A must be in group A, B, or C to communicate with the Nissin Air 1 Commander.  Also, confirm that the Air 1 Commander and the i60A are set to the same channel.  If they are on different channels the flash will not fire. 

Q:  How do I prevent my flash from beeping every time I change a setting on the Air 1 Commander?

A:  All Nissin NAS system flashes will emit an audio confirmation "beep" whenever a setting is changed.  To mute this sound, simply press the on/off button on the Air 1 (A, B, or C must NOT be flashing). The color of the flash test button will change from orange (beep) to white (mute).

Q:  How do I change the channel on the Nissin Air 1 Commander?

A: If you are getting radio interference and need to change the channel on the Air 1 Commander, then press and hold the “S” set button for 3 seconds. Rotate the center dial to select 1 of the 8 available channels displayed in the “B” row (the channels are represented by orange bars). Press the set button again to confirm your selection.

If your Air 1 Commander is paired to the Nissin Di700A flash, then you do not need to change any settings on your flash. The Di700A will automatically update its channel to match the Air 1 Commander.

If your Air 1 Commander is paired to the Nissin i60A, and the flash is set to the “A” Auto Channel, then you do not need to change any settings on your flash. However, if the i60A has been manually set to channels 1-8, then you will need to manually update channel on your flash to match the new Air 1 Commander channel.

Q:  I paired my Nissin Air 1 Commander to my Nissin Air R Receiver, but the flash will not fire.

A:  Confirm that the Air 1 Commander and the Air R Receiver are set to the same channel.  If they are on different channels the flash will not fire. 

Q:  High-Speed Sync (HSS) is not working with the Nissin Air 1.

A:  First, confirm that your camera model supports HSS (not all cameras do). 

To use HSS on Sony and Micro Four Thirds cameras you must activate the HSS function on your Nissin Air 1 Commander.  To activate HSS on the Air 1 press the pilot button for 3 seconds until the button starts to blink (this button will blink while HSS is active).  To deactivate HSS, press the pilot button again until the button stops blinking.  

To use HSS on Canon, Nikon, and Fuji cameras you must activate HSS (FP) from the camera's flash menu.  Once HSS is activated in the camera the signal will pass through the Air 1 to the flash.  You do not need to change any other Air 1 or flash settings.

Nissin Air 10s Commander


Q:  The Nissin Air 10s Commander is not communicating with my Nissin i60A, Di700A, or Air R Receiver.  The Air 10s and flashes are paired, but I am unable to change the power or make other setting changes on the flashes.

A:  Confirm that your Air 10s Commander AND your flashes are using the correct channel.  Also, confirm that your Air 10s Commander is in "Basic Mode" when using these flashes.  See below for more information.

If your Air 10s Commander is not communicating with your i60A or Air R Receiver, then confirm that the i60A or Air R Receiver ARE NOT manually set to channel 1.  These units are not compatible with the Air 10s on Channel 1.  

When pairing the Air 10s Commander with the Nissin i60A, Di700A, and Air R Receiver, the Air 10s will automatically select channel 2 as a default.  To ensure proper communication between your Air 10s and flashes, confirm that your flashes are set to the Auto channel (recommended), manually select channel 2, or if you are experiencing interference choose another channel for the network (choose from channels 2-8).  

Lastly, the Air 10s Commander offers a "Basic Mode" and "Advanced Mode".  The i60A, Di700A, and Air R Receiver are not compatible with the Air 10s Commander's "Advanced Mode".  Confirm that your Air 10s Commander is set to "Basic Mode" when using these flashes.  

Q:  Why is my Nissin i60A not responding to the 1/3 EV step power adjustments from my Nissin Air 10s Commander?

A:  If the i60A is not responding to the 1/3 EV steps from the Air 10s Commander, but is responding to other commands from the Air 10s, then the i60A requires a firmware update.  Please contact us for instructions about how to update the firmware on your flash.

Q:  High-Speed Sync (HSS) is not working with the Nissin Air 10s.

A:  First, confirm that your camera model supports HSS (not all cameras do). 

To use HSS on Sony and Micro Four Thirds cameras you must activate the HSS function on your Nissin Air 10s Commander.  Press and hold the "H" on the center button until the "H" with the lightning bolt appears on the display.  To deactivate HSS, press the center button again until the "H" disappears from the display.

To use HSS on Canon, Nikon, and Fuji cameras you must activate HSS (FP) from the camera's flash menu.  Once HSS is activated in the camera the signal will pass through the Air 10s to the flash.  You do not need to change any other Air 10s or flash settings.

Q:  Will the Open Mode on the Nissin Air 10s Commander work with the Nissin Di700A, i60A, or Air R Receiver?

A:  No.  The "OPEN" mode on the Air 10s Commander is not compatible with the Di700A, i60A, or the Air R Receiver.  Open Mode is only compatible with the newer Nissin flashes such as the MG80 Pro, MG10, and MG8.

Q:  How do I prevent the zoom on my remote flash from changing every time I change the focal length on my lens?

A:  The Nissin Air 10s Commander offers users the option of selecting "A" Auto Zoom or Manual Zoom mode on flashes in remote groups.  When in the Auto Zoom mode a remote flash's zoom automatically syncs with the camera lens' focal length.

To change the zoom setting on a remote flash press and hold "M. zoom" on the Selector Dial of the Air 10s for about 2 seconds. Next, press the flash's group button (A, B, C, or D) until the group letter blinks, then rotate the Selector Dial to the desired zoom focal length.

Shooting HSS (high-speed sync) with Nissin Flashes

Q: HSS (high-speed sync) does not work when the flash head is in the bounce position.

A: Some camera manufacturers, including Sony, disable HSS when the flash head is moved to a bounce position because the higher power consumption of HSS's rapid fire flashing reduces the flash's effective range. This renders bounce flash ineffective under most conditions.  Nissin follows each manufacturer's protocols with regards to allowing bounce flash when using HSS.

Q: When using HSS (high-speed sync) in Manual mode I cannot set the power below 1/32.

A: Nissin flashes offer a range of 1/1 to 1/32 power when using HSS in Manual mode, and power output levels below 1/32 are not permitted.  The flash will reset to 1/32 (minimum factory default for HSS) if you attempt to reduce the power below 1/32.

Nissin MF18 Macro Ring Flash

Q:  Can the LED modeling light on the Nissin MF18 Macro Ring Flash be used to assist with focusing in low light conditions?

A:  Yes, the LED modeling light on the Nissin MF18 can be used to help focus your camera in low light.  To turn on/off the modeling light press the "Set" button for 2 seconds.

Q:  Is the Nissin MF18 Macro Ring Flash compatible with the Sony a6600?  

A:  Yes, the Nissin MF18 Macro Ring Flash is compatible with the Sony a6600.

Nissin Di700A

Q: My Di700A flash will not turn on.

A: Check the negative contacts on your flash’s AA battery magazine. The metal springs located at the bottom of the battery magazine should be angled up at approximately 30˚ to maintain contact with the battery. If one or more of these contacts have flattened then the flash will not power on.

Fortunately, there is a quick and easy solution. You can restore the angle of the metal spring to its original position by placing the tip of a small screw driver under the end of the metal spring and gently lifting up. Be careful not to lift the metal spring beyond 45˚.

If you are uncomfortable doing this yourself then please contact us directly to inquire about a repair. Additional battery magazines are also available for purchase here.

Nissin i60A

Q:  Why is my Nissin i60A not responding to the 1/3 EV step power adjustments from my Nissin Air 10s Commander?

A:  If the i60A is not responding to the 1/3 EV steps from the Air 10s Commander, then the i60A requires a firmware update.  Please contact us for instructions about how to update the firmware on your flash.

Nissin i400

Q:  How do I activate high-speed sync (HSS) on my Nissin i400?

A:  To activate / deactivate HSS on the Nissin i400 (Sony and 4/3 models only) press and hold the pilot light for 3 seconds.  On Canon, Nikon, and Fuji camera systems HSS is activated through your camera menu.

Q:  The pilot light on my Nissin i400 changed color from green to blue, pink, aqua, or yellow. What does this mean?

When the Nissin i400 is in the “A” or “TTL” mode the flash will default to the “Auto” flash zoom head setting (green pilot light), which means the flash zoom will sync with the focal length of your camera’s lens. It is not possible to change the Auto zoom setting when using the flash in the “A” or “TTL” mode.

However, when the Nissin i400 is set to Manual mode you can manually change the flash’s zoom from Auto to one of the following fixed zoom settings: Auto (green), 24 (blue), 50 (pink), 80 (aqua), 105 (yellow). Each zoom setting is represented by a different color pilot light. For example, a green pilot light indicates the flash’s zoom is set to Auto, a blue pilot light indicates the zoom is set to 24mm, etc.

To change the flash's zoom setting when in Manual mode, simply hold down the on/off button for 3 seconds (with the flash already turned on). The pilot light will change color to reflect the new zoom setting. Repeat this step to set the flash to the desired zoom setting.

Q:  Why is the pilot light blinking on my Nissin i400?

A:  You have inadvertently activated HSS (high-speed sync) on your Nissin i400.  To activate / deactivate HSS on the i400 (Sony and 4/3 models only) press and hold the pilot light for 3 seconds.  On Canon, Nikon, and Fuji camera systems HSS is activated through your camera menu.

Nissin i600

Q:  How do I activate high-speed sync (HSS) on my Nissin i600?

A:  To activate / deactivate HSS on the Nissin i600 (Sony and 4/3 models only) press and hold the pilot light for 3 seconds.  On Canon, Nikon, and Fuji camera systems HSS is activated through your camera menu.

Q:  Why is the mode light blinking on my Nissin i600?

A:  You have inadvertently activated HSS (high-speed sync) on your Nissin i600. To activate / deactivate HSS on the i600 (Sony, 4/3, and Fuji models) press and hold the pilot light for 3 seconds.  On Canon and Nikon camera systems HSS is activated through your camera menu.

Q:  My Nissin i600 has an A, B, C group setting printed on the flash's mode dial.  Will these group settings work with the Nissin Air 1 or Air 10s Commander?

A:  No, the Nissin i600 cannot be used with the Nissin Air 1 or Air 10s Commander because it does not have a built-in radio receiver.

The A, B, and C groups indicated on the i600 can only be used in conjunction with the camera manufacturers’ own infrared TTL optical systems, such as Nikon's Creative Lighting System (CLS).

Nissin i40

Q:  How do I activate high-speed sync (HSS) on my Nissin i40?

A:  To activate / deactivate HSS on the Nissin i40 (Sony and 4/3 models only) press and hold the pilot light for 3 seconds.  On Canon, Nikon, and Fuji camera systems HSS is activated through your camera menu.

Q:  My Nissin i40 has an A, B, C group setting printed on the flash's mode dial.  Will these group settings work with the Nissin Air 1 or Air 10s Commander?

A:  No, the Nissin i40 cannot be used with the Nissin Air 1 or Air 10s Commander because it does not have a built-in radio receiver.

The A, B, and C groups indicated on the i40 can only be used in conjunction with the camera manufacturers’ own infrared TTL optical systems, such as Nikon's Creative Lighting System (CLS).

Q:  The Nissin i40 has several color bars with “Auto, 24, 50, 80, 105” printed on top of the flash head underneath the built-in bounce card. What is this for?

A: This is a quick reference chart that refers to the Nissin i40’s zoom head setting. The color of the i40’s pilot light will change to match one of the colors on the chart, and its corresponding zoom head setting. For example, a green pilot light indicates the flash’s zoom is set to Auto, a blue pilot light indicates the zoom is set to 24mm, etc.

You can manually adjust the zoom setting of the i40 when using the flash off-camera in the M, SD, SF, or wireless mode. To change the zoom setting, simply hold down the on/off button for 3 seconds (with the flash already turned on). The pilot light will change color to reflect the new zoom setting. Repeat this step to set the flash to the next zoom setting on the quick reference color chart.

When the pilot light is green the flash is in the Auto Zoom mode, and when mounted on a camera the flash will communicate with the camera body to automatically set the zoom head to the proper position.

Nissin MG80 Pro

Q: The Nissin MG80 Pro will not respond to commands from the Nissin Air 10s Commander.

A:  The Nissin Air 10s Commander and Nissin MG80 Pro must be paired, set to the same radio channel, and using the same Group.

  1. Confirm the MG80 Pro and Air 10s Commander are paired correctly.  You can watch a quick 30 second video about how to pair them here.
  2. To use the MG80 Pro off-camera the flash must be set to the 'SL' slave mode. With the flash turned on, press and hold the power button for 3 seconds to select 'On', CO', or 'SL'. Rotate the dial to 'SL' then press the center of the dial to confirm.
  3. Set the radio channel on the MG80 Pro to 'A'.  If experiencing radio interference then manually select another radio channel for the MG80 Pro and Air 10s Commander (the same channel for both).
  4. The default group for the MG80 Pro is Advanced Group Ȧ, but the flash can be set to one of 8 different groups including, Advanced Group Ȧ, Ḃ, Ċ, Ḋ, or Basic Group A, B, C, D.  The MG80 Pro's group setting is displayed along the left edge of the screen.  To switch the MG80 Pro from an Advanced Group to a Basic Group press and hold the modeling light button for 3 seconds, then press the A, B, C, or D button to assign the flash to that group.
  5. Confirm the Air 10s Commander displays the same Advanced or Basic group that is assigned to the MG80 Pro. For example, the Air 10s must display Advanced Group Å if the flash is set to Advanced Group Å. To change the group selected on the Air 10s from Basic to Advanced press and hold the modeling light button on the Air 10s for 3 seconds.

  1. Green:  flash is ready to fire.
  2. Red:  flash is charging - pilot light will turn green when flash is ready.
  3. Yellow:  battery problem - turn off flash and check batteries. 
    • low battery power
    • incorrect installation of battery polarity or type
    • battery temperature (too hot)

Q:  Does the Nissin MG80 Pro use a quartz or glass flash tube?

A:  The MG80 Pro utilizes a quartz flash tube because this type of flash tube delivers superior heat resistance, durability, and a longer life span than a standard glass flash tube.

Q:  The Auto Zoom on my Nissin MG80 Pro isn't working.  Am I doing something wrong?

A:  The MG80 Pro flash head can be set to the following vertical positions for lighting subjects in front of the camera as well as for bounce flash:  -7˚, 0˚, 45˚, 60˚, 75˚, and 90˚.

Nissin MG80 Pro Flash Head Angles

The MG80 Pro's Auto Zoom function only works when the flash head is in the 0˚ position (straight ahead). If the flash head is in any other position, for example -7˚ (pointing slightly down), then the Auto Zoom will not sync the flash with your lens' focal length.  To use Auto Zoom confirm that your flash head is at 0˚.

Use Manual Zoom to change the zoom setting on the flash when the flash's head is in any position other than 0˚.

Q:  What is the difference between the 14500 Lithium ion, AA NiMH rechargeable, and AA Alkaline battery types when they are installed in the Nissin MG80 Pro?

Lithium Ion 3.7v 1000mAH
4x Li-on batteries: 14.8 volts

3.7 second recycle

Q:  Does the Nissin MG80 Pro support flat top and button top type batteries?

A:  Yes, the MG80 Pro supports both flat top and button top type batteries.  However, we recommend using button top batteries because this type includes built-in safety circuitry designed to protect the battery against over charging.

Q:  Can I use different battery types at the same time in the Nissin MG80 Pro?  For example, can I mix AA Alkaline with AA NiMH Rechargeable batteries?

A:  No.  Do not mix and match battery types in the Nissin MG80 Pro.  Only use the same battery type at one time, for example 4x 14500 lithium ion, 4x AA NiMH Rechargeable, or 4x AA Alkaline batteries.  If you accidentally install different battery types the pilot light will display yellow and the flash will not function.

Q:  How do I adjust the power when the Nissin MG80 Pro is in Command Mode?

A:  The Nissin MG80 Pro defaults to Advanced Group Å.  To access the command screen for the Advanced Group when the flash is displaying the Basic Group simply press and hold the modeling light button for 3 seconds. 

Q:  Will the Nissin MG80 Pro connect to an external battery pack?

A:  No, the Nissin MG80 Pro does not have an external battery pack connector.  The MG80 Pro was designed to use multiple battery types, including 4x lithium ion type 14500 batteries.  The 14500 lithium ion batteries offer comparable performance compared to an external battery pack without the battery pack's additional size and weight.  The 14500 lithium ion batteries are also much less expensive than a battery pack.

Nissin MG10

Q:  Sometimes the Nissin MG10 will not fire, but another Nissin flash paired with my Air 10s Commander is working fine.

A:  You may need to update the firmware on your Nissin MG10.  Click here for instructions to check the firmware version installed on your flash.  If your firmware is out of date, follow the instructions to download and install the latest version on your flash.  

Q: Will the Nissin MG10 connect to the Nissin PS8, or other external battery pack?

A:  Yes, the Nissin MG10 will connect to an external battery, such as the Nissin PS8, with a Sony style power cord.  When using an external battery the MG10 requires internal AA or Li-on type 26650 batteries to power the flash's electronics because an external battery only provides power to the flash head when firing.

The Nissin MG10 was designed to use multiple battery types, including 2x lithium ion type 26650 batteries (5000 mAh each).  These lithium ion batteries offer 3x more energy capacity than the PS8 battery pack (10,000 mAh vs. 3000 mAh) without the additional size, weight, and higher cost of a battery pack. 

However, the PS8 battery pack delivers an ultra fast recycle time of .5 -.7 seconds compared to the full power recycle time of 1.5 seconds for lithium ion batteries.

Q: How can I use the X-Sync on the Nissin MG10?

A:  Just plug in the cable, turn "Gr" to "Red Dot" to switch on x-sync mode. For power control, rotate the "Ch". For Example. Ch A stands for 1/256 power and so on up to the A which is 1/1 power.  For further information, see page 15 of the User Manual: Download Manual.

Using Nissin Flashes with Fuji Cameras

Q:  What off-camera cord do I use with my Nissin Fuji version flash?

A:  Use a Canon type off-camera cord with the Nissin Fuji version flash.

Using Nissin Flashes with Leica Cameras

Q: Can I use the Leica SF C1 Commander with Nissin flashes?

A: The Leica SF C1 Commander will support Nissin Air System (NAS) capable flashes (off-camera only), provided the flashes are updated with the latest firmware. The SF C1 can be used to fire the following Nissin flashes: Di700A, i60A, MG10, MG80 Pro.

Q: Can I use a Nissin flash in the hot shoe of my Leica camera?

A:  No. Nissin flashes do not support the Leica TTL flash system, and they will not work properly when placed in the on-camera hot shoe. For on-camera flash photography you must use a Leica version flash such as the SF 60.

Using Nissin Flashes with Sony Cameras

Q:  My Nissin flash and Nissin Air 1 Commander are paired and communicate when off-camera, but when the Air 1 Commander is mounted to the hot shoe on my Sony camera the flash will not fire.

A:  To control an off-camera flash a Sony Camera must be in the "WL" mode. Place the Nissin Air 1 Commander in the hot shoe, then activate the "WL" mode in the flash menu.

Q:  Why can't I access Rear Curtain Sync on my Sony Camera when using the Nissin Air 1 Commander?

A:  Rear Curtain Sync cannot be activated on older model Sony cameras when also using the WL mode for off-camera flash.  This is because two functions located in the same Sony camera sub-menu cannot be activated at the same time.

Note.  Sony updated the flash menu to separate the WL feature from other flash functions on newer cameras such as the A7III and A7RIII.  On these cameras it is possible to activate the Rear Curtain Sync mode when using off-camera flash with the WL mode activated.

Auto Focus Assist light (AFAL)

Q:  Does my Nissin flash have an AF-Assist light?  Is it working?

A:  The following Nissin Flashes include a built-in AF-assist light (AFAL):  i400, i600, i40, i60A, Di700A, MG80.

When a camera body has its own built-in AF-Assist light the camera will not send a signal to a flash to activate the on-flash AF-Assist light.

This means that your flash's AF-assist light WILL activate when used with a camera body that DOES NOT have its own AFAL, and your flash’s AF-assist light WILL NOT activate when used with a camera body that DOES have its own AFAL.

SD / SF Optical Slave Modes:

Q: What are the SD and SF optical slave modes on my flash?

A:  The SD and SF optical slave modes are used to trigger off-camera flashes in the absence of a wireless radio commander, or when the flashes lack radio receives.  When an off-camera flash is set to the SD or SF slave mode, it will fire when its optical sensor receives light input from the firing of another flash. 

Q: What is the difference between the SD and SF optical slave mode?

The SD, or slave digital setting should be used on the slave flash when the master flash is set to TTL. In the SD setting, the slave flash will ignore the TTL “pre-flash” from the master flash and synchronize with the second “exposure” flash. When using the SD slave mode, set the power of the slave flash manually.

The SF, or slave film setting should be used on the slave flash when the master flash is set to Manual. Since there is no pre-flash when shooting in Manual, in the SF setting the slave flash will synchronize with the master flash every time it fires. When using the SF slave mode, set the power of the slave flash manually.

Q: My slave flash will not fire when using the SD optical slave mode

A: Confirm the master flash is in TTL mode. When using the SD slave mode, the slave flash will not fire when the Master Flash is in Manual mode.

Check to confirm the optical sensor on the slave flash is receiving light from the Master flash.  The slave flash will not fire if its optical sensor is blocked, or shielded from light emitted by the Master Flash.

Q: My slave flash is firing when using the SF slave mode, but it is not contributing any light to the image.

A: The Master Flash is set to TTL, and the slave flash is firing on the TTL pre-flash (before the image capture). Change the slave flash to the SD optical slave mode.
