Overheating protection mode: If the operating temperature of the VC-310C is too high after several
full-power ashes, the ash will enter the overheating protection mode. The thermal warning indicator [TP-HI]
will appear on the LCD, and you should let the ash cool down for a period of 2–5 minutes.
Default setting: You can restore the ash to its original settings. To do this, rst make sure the ash is off.
Press and hold the Set and Power buttons for 3 seconds, then release.
LED preview and focusing: There are three LEDs built into the ash head that can be used as a preview light
to illuminate the subject for reference, or as an autofocus assist light.
To use the LEDs as a preview light, press the power button while the ash is on. To turn the preview light off,
press the power button again.
The LEDs will function as an autofocus assist light whenever you press the camera’s shutter release halfway.
