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.
• When the over-temperature protection is started, is shown on
the LCD panel.
