Turning On The Power - Canon Speedlite 600EX-RT Instruction Manual

Turning on the Power

About Quick Flash
The Quick Flash function enables flash shooting while the flash-ready
lamp is green (before the flash is fully charged).
The guide number is 1/2 to 1/6 of the full output, but it is useful for
shooting with a faster recycling time at a short shooting distance.
Set the drive mode to single shooting. You cannot use Quick Flash
when continuous shooting, FEB, manual flash or stroboscopic flash is
set.
About Auto Power Off
To save battery power, the power will turn off automatically after approx.
90 sec. of idle use. To turn on the Speedlite again, press the camera's
shutter button halfway, or press the test flash button (flash-ready lamp).
During radio transmission wireless master flash shooting (p.59) or
during linked shooting (p.73), the time until auto power off takes effect is
5 min.
Quick Flash cannot be used when the flash mode is set to <b>.
