● To avoid overheating and deteriorating the flash head, do not fire
more than 40 continuous flashes in fast succession at 1/1 full

minutes.
● If you fire more than 40 continuous flashes and then fire more
flashes in short intervals, the inner over-temperature protection
function may be activated. 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,
