Optic S1 Secondary Unit Setting
In M manual flash mode, press <S1/S2> button so that this flash can function as an optic S1 secondary flash with the optic sensor. With this function, the flash will fire synchronously when the main flash fires, the same effect as that by the use of radio triggers. This helps create multiple lighting ffects.
Optic S2 Secondary Unit Setting
Press <S1/S2> button so that this flash can also function as an optic S2 secondary flash with the optic sensor in M manual flash mode. This is useful when cameras have a pre-flash function. With this function, the flash will ignore a single “preflash” from the main flash and will only fire in response to the second, actual flash from the main unit.

Calculating the Shutter Speed

During the stroboscopic flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera.
Number of Flashes / Flash Frequency = Shutter Speed
For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the shutter speed should be at least 2 seconds.

Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 62To avoid overheating and deteriorating the flash head, do not use stroboscopic flash more than 10 times in succession. After 10 times, allow the camera flash to rest for at least 15 minutes. If you try to use the stroboscopic flash more than 10 times in succession, the firing might stop automatically to protect the flash head. If this happens, allow at least 15 minutes’ rest for the camera flash

Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 63● Stroboscopic flash is most effective with a highly reflective subject against a dark background.
● Using a tripod and remote control is recommended.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash.
● Stroboscopic flash can be used with“buLb”.
● If the number of flashes is displayed as “–”, the firing will continue until the shutter closes or the battery is exhausted. The number of flashes will be limited as shown by the following table.

Using Automatic Wireless Flash with Multiple Slave Units

When stronger flash output or more convenient lighting operation is needed, increase the number of slave units and set it as a single slave unit.
To add slave units, use the same steps as setting “automatic wireless flash with a single slave unit”. Any flash group can be set (A/B/C/D/E).
When the number of slave units is increased and the master unit flash firing is ON, automatic control is implemented to make all groups of flashes fire the same flash output and ensure the total flash output up is to standard exposure.Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 82

If you fire the modeling flash 10 consecutive times, allow at least 10 minutes break for the camera flash.
● The modeling flash cannot be fired with the EOS 300 and Type-B cameras.

Auto Focus Assist Beam

In poorly-lit or low-contrast shooting environments, the built-in autofocus assist beam will automatically light on to make it easier for autofocus. The beam will light up only when autofocus is difficult and get out as soon as the autofocus becomes correct. If you want to turn off the autofocus assist beam, set the “AF” to “OFF” on the C.Fn settings.
Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 91● If you find the autofocus assist beam does not light up, this is because the camera has got the correct autofocus.

Position Effective Range
Center 0.6-10m / 2.0-32.8 feet
Periphery 0.6-5m / 2.0-16.4 feet
Bounce Flash

By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for a more natural-looking shot. This is called bounce flash.
To set the bounce direction, hold the flash head and turn it to a satisfying angle. Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 92

Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 93● If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure.
● The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface is not white, a color cast may appear in the picture.

ZOOM: Setting the Flash Coverage

The flash coverage can be set automatically or manually. It can be set to match the lens focal length from 28mm to 105mm.

In Manual Zoom mode, press the <ZOOM> button.

Protection Function

1. Over-Temperature Protection

  • To avoid overheating and deteriorating the flash head, do not fire more than 30 continuous flashes in fast succession at 1/1 full power. After 30  continuous flashes, allow a rest time of at least 10 minutes.
  • If you fire more than 30 continuous flashes and then fire more flashes in short intervals, the inner over-temperature protection function may be activated and make the recycling time over 10 seconds. If this occurs, allow a rest time of about 10 minutes, and the flash unit will then return to normal.
  •  When the over-temperature protection is started, is shown on the LCD display. A number of flashes that will activate over-temperature protection:
Power Output Level Number of Flashes

    →Wait until the flash is fully recycled and the flash-ready indicator lights up.
    →If the flash-ready indicator lights up, but <Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 102 > or < Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 103> is not displayed in the viewfinder, check whether this flash unit is securely attached to the camera hot shoe.
    →If the flash-ready indicator does not light up after a long wait, check whether the battery power is enough. If the battery power is low, <Godox TTL Li-ion Round Head Camera Flash Instruction Manual  & troubleshooting 104 > will appear and blink on the LCD panel. Please replace the battery immediately.

    →Press any flash button to wake up.
    Auto-zoom does not work.
  •  The camera flash is not attached securely to the camera.
    →Attach the camera flash’s mounting foot to the camera.
    The flash exposure is underexposed or overexposed.
  • There was a highly reflective object (e.g. glass window) in the picture.
