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.
