If you turn on the "RED EYE REMOVAL" in the camera menu,
the pre-flash will be fired just before the main flash to mitigate the
red-eye effect of the subject.

SETTING” in the camera menu, the flash will fire just before the
shutter closes.
When shooting a low-contrast object or in a dark place, the auto focus
assist light is automatically emitted to the subject to facilitate focusing.
The irradiated autofocus assist light does not appear in the captured image.

In the FP mode, the light emission method places a heavy load on the flash,
so if the flash head overheats, a safety function to protect the device will be
activated and the charging interval will be automatically limited to 12
seconds. The limit is automatically released when the temperature drops.
