Protection Function
1. Over-Temperature Protection
To avoid overheating and deteriorating the flash head, do not re more
than 100 continuous flashes in fast succession at 1/1 full power. After 100
continuous flashes, allow a rest time of at least 10 minutes.
If you re more than 100 continuous flashes and then re more flashes
in short intervals, the inner over-temperature protection function may be
activated and make the recycle 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
display.
1. If flash exposure compensation has already been set with the camera flash, flash
exposure compensation cannot be set with the camera. To set it with the camera,
the camera flash’s flash exposure compensation must be set to zero.
2. If any flash custom functions and flash settings other than flash exposure
compensation have been set by both the camera and the flash, the latest settings
will take effect.
