Over-temperature protection
• To avoid overheating and damage to the flash head,
do not fire more than 30 continuous flashes in fast
succession at 1/1 full power. After 30 continuous
flashes, let your flash cool for at least 10 minutes.
• If you fire more than 30 continuous flashes, then fire
more flashes in short intervals, the internal
over-temperature protection function may be
activated and make the recycling time over
10 seconds. If this occurs, let your flash cool about
10 minutes.
• When the over-temperature protection is started, is
displayed on the LCD.
The number of flashes that will activate the overheating
protection based on the power output level are:
