Calculating the Shutter Speed
During multi 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 flash frequency is 5Hz, the shutter speed should be at least 2 seconds.

To avoid overheating and deteriorating the flash head, do not use multi 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 multi 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.

1. Multi flash is most effective with a highly reflective subject against a dark background.
2. Using a tripod and TTL flash trigger XPROII is recommended.
3. A flash output of 1/1 and 1/2 cannot be set for multi flash.
4. Multi flash can also be used with "buLb" mode.
5. Multi flash mode cannot be set in high-speed sync mode.
6. Please turn off the multi flash when not using, otherwise TTL flash and M flash are not available.

Other Applications

Sync Triggering
The sync cord jack is a Φ2.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.

Modeling Flash
If the camera has a depth-of-field preview button, pressing it will fire the flash continuously for 1 second. This is called modeling flash. It enables you to see the shadow effects on the subject and the lighting balance. You can fire the modeling flash during wireless or normal flash shooting.

Note:

1. To avoid overheating and deteriorating the flash head, do not fire the modeling flash for more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow at least 10 minutes' break for the camera flash.
2. The modeling flash cannot be fired with the Canon EOS 300 and Type-B cameras.

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.

Note:

1. If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure.
2. 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.

Low Battery Warning
If the battery power is low, the <> icon will turn red. Please replace or charge the battery immediately.

Control with the Camera's Menu

If the camera flash is attached to an EOS camera which has a camera control function, the flash can be controlled using the camera's menu screen.

The functions that can be set are as follows. The available settings vary depending on the flash mode, wireless flash function settings, and other conditions.

Setting Camera Flash Functions

1. Select <Flash control> or <External Speedlite control>.
   
2. Select <Flash function settings> or <External func. setting >.
   
3. The setting screen and items displayed vary depending on the camera.
   

1. To clear all custom function settings, you can enter the [Clear settings] in step 2 and select [Clear all Speedlite C.Fn's] or [Clear ext. flash C.Fn set.].
2. If flash exposure compensation has already been set with the camera flash, flash exposure compensation cannot be set with the camera. To set it with the camera, the camera flash's flash exposure compensation must be set to zero.
3. If any flash custom functions and flash settings other than flash exposure compensation have been set by both the camera and the flash, the latest settings will take effect.

Protection Function

Over-Temperature Protection

• To avoid overheating and deteriorating the flash head, do not fire more than 70 continuous flashes in fast succession at 1/1 full power. After 70 continuous flashes, allow a rest time of at least 10 minutes.
• If you fire more than 70 continuous flashes and then fi re more flashes in short intervals, the inner over-temperature protection function may be activated and make the recycle 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.

Number of flashes that will activate over-temperature protection:

The Reason & Solution of Not Triggering in Godox 2.4G Wireless

1. Disturbed by the 2.4G signal in outer environment (e.g. wireless base station, 2.4G wifi router, Bluetooth, etc.)

→ To adjust the channel CH setting on the flash trigger (add 10+ channels) and use the channel which is not disturbed. Or turn off the other 2.4G equipment in working.

2. Please make sure that whether the flash has finished its recycle or caught up with the continuous shooting speed or not (the flash ready indicator is lightened) and the flash is not under the state of over-heat protection or other abnormal situations.

→ Please downgrade the flash power output. If the flash is in TTL mode, please try to change it to M mode (a pre-flash is needed in TTL mode).

3. Whether the distance between the flash trigger and the flash is too close or not (<0.5m).

→ Please turn on the "close distance wireless mode":

X1 Series: Press and hold the triggering button then turn on the device until the indicator blinks twice.

Xpro and X2T Series: Set the C.Fn-DIST to 0-30m.

X3 Series: Set the triggering distance to 0-30m.

4. Whether the flash trigger and the receiver end equipment are in the low battery states or not

→ Please replace the battery or charge it in time.

5. The flash trigger's firmware is an older version

→ Please upgrade the firmware of the flash trigger referring to the instruction manual for specific firmware upgrades.
