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.
