- The battery must not be used while it is being charged.
- The battery is equipped with an over-temperature protection function. If the internal temperature of the battery reaches 131°F/55℃, this function will activate automatically. The battery will need to cool down before normal operation is resumed.
Notes
If the shutter speed is set equal to, or slower than, the maximum flash sync speed of the camera, the ""
"" icon will not be displayed in the viewfinder. With High Speed Sync, the higher the shutter speed, the smaller the effective flash range.
To resume normal flash, press the High Speed Sync button again. The ""
"" icon will disappear.
High speed sync flash is not available in Multi Flash mode.
The flash features an overheat protection function which will kick in after 50 consecutive high speed synchronized flashes.
Flash Mode - M Manual Flash Mode
M Mode allows you to set the flash output in 0.1-stop increments from 1/256 power to 1/1 full power. To obtain the correct flash exposure, please use a handheld flash meter to determine the required flash output.
- Setting the Flash Power to M mode
Short press the mode button "MODE". When "M" appears on the screen, the flash has been set to M mode.
The flash output can be set by turning the adjustment wheel. Press the "SET" setting button again to confirm the flash output.
![]()
- Setting the S1 Optical Unit
In M Manual Flash Mode, press the <MENU> button to enter the C.Fn - SLAVE and select S1. The flash can be used as a secondary light to create a variety of lighting effects, suitable for a manual flash environment. It will trigger the flash synchronously with the first flash of the master flash which is the effect consistent with the use of wireless flash triggers.
![]()
- Setting the S2 Optical Unit
Press the <MENU> button to enter C.Fn - SLAVE and select S2. The flash can be used as a secondary light for TTL flash environments. With the anti-pre-flash function, the camera with a pre-flash function can be used to synchronize shooting with the optic slave. It will trigger the flash synchronously with the second flash of the main flash, that is, a two light-controlled flash.
※ The S1/S2 optical slave flash mode is supported only in M mode when the wireless function is turned off.

- Displaying the Flash Duration
Flash duration is the time from the start of the flash to reach the half-peak of light. Half-peak is expressed as t = 0.5. In order to provide photographers with more detailed shooting t values, this product uses t = 0.1. The difference between t=0.5 and t=0.1 is shown on the left.
![]()
※ Flash Duration is displayed only in M mode.

Flash Mode - Multi Flash Mode
The Multi Flash Mode emits a series of rapid flashes. It allows users to take multiple images of moving objects in a single picture. You can set the flash frequency (the number of flashes per second, expressed in Hz), the flash times and the flash output power.
- Setting the Multi Flash Mode
When the word "MULTI" appears on the screen, the flash is now set in strobe mode. The flash output can be set by rotating the wheel.
Press the "SET" button again to set the number of flashes and rotate the dial to set the value. Press the "SET" button again to set the flash frequency and rotate the dial to set the value. Finally press the "SET" button again to set all values.
![]()
- Calculating the Shutter Speed
In Multi Flash Mode, the shutter should remain open until the flash stops. Use the following formula to calculate the shutter speed, and then set the camera.
Shutter Speed = Flash Times/Flash Frequency
For example, if the Flash Times is 10 and the Flash Frequency is 5Hz, the shutter speed should be at least 2 seconds.
To prevent overheating and damage to the flash, do not perform multi strobes/flashes of more than 10 consecutive flashes. After 10 flashes, let the flash cool down for at least 15 minutes. If you try to perform more than 10 consecutive multi strobes/flashes, the flash may stop automatically to prevent the flash head from overheating. If this happens, let the flash cool down for at least 15 minutes.
Notes
- Very reflective subjects are more effective with strobe flashes in front of a dark background.
- The use of a tripod and remote is recommended.
- Multi Flash Mode cannot be set when the flash output is 1/1 and 1/2.
- Multi Flash Mode can also be used with "buLb".
- If the flash time is displayed as --, the light will flash continuously until the shutter or battery is exhausted.
The flash times will be limited as shown in the table below.

- Causes and Solutions of 2.4G Wireless Flash Leakage
- The external environment 2.4G signal interference (such as wireless base stations, 2.4G Wi-fi routing, Bluetooth devices, etc.).
Please adjust the channel CH setting of the flash trigger (recommended +10), find a channel without interference to use, or turn off other 2.4G devices whilst working. - Please confirm whether the flash has been recycled or the recycling time has kept up with the continuous shooting speed (flash ready indicator has been lit), and is not in the overheat protection or other abnormal state. You can try to adjust the flash power setting, such as TTL mode. Please try to change to M mode (since TTL mode requires a single pre-flash).
- The distance between the trigger and flash is too close (distance <0.5m). Please turn on the flash trigger "close to wireless mode": Qpro series: Set C.Fn-DIST for 0-30m.
- The flash and the trigger are both low on power. Please replace the battery (recommended to use 1.5V disposable alkaline type batteries for the trigger).
