About Auto Power Off
To save battery power, the power will be off automatically after a certain 
period of idle use. 
● The flash will enter sleep mode after approx. 90 seconds of idle use 
when being attached to the camera. 
● Setting as off camera mode, namely, the S1/S2 slave triggering mode, 
the flash will enter sleep mode after approx. 60 minutes (adjustable, 30 
minutes by default).

To avoid overheating and degrading the flash head, do not 
fire more than 20 continuous flashes. After 20 continuous 
flashes, allow a rest time of at least 10 min. 
If you fire more than 20 continuous flashes and then fire 
more flashes in short intervals, the inner overheating 
prevention function may be activated to make the recycling 
time about 8 to 20 sec. If this occurs, allow a rest time of 
about 15 min, and the flash will then return to normal.

Getting Started and Basic Operation
03
04
If < > blinks on the LCD panel, the 
battery power is low and the camera 
flash stops charging. In this case, the 
<ZOOM> button is disabled. Please 
change the batteries immediately.
● Using size-AA batteries other than the alkaline type may cause 
improper battery contact due to the irregular shape of the battery 
contacts. 
● If you change the batteries after firing many flashes continuously, 
be aware that the batteries might be hot.
When the Power Switch is set to ON and the flash power is off 
automatically after a certain period of idle use, power 
consumption exists and long-time power discharge damages 
batteries. Therefore, make sure to shut down the flash power by 
setting the Power Switch to OFF if the flash is not used for long.
