Turning On The Power - Canon Speedlite 470EX-AI Instruction Manual

Turning on the Power

Flash-ready lamp
(Test flash button)
Quick Flash Function
The Quick flash function enables flash photography when the flash-
ready lamp is lit green (before the flash is fully charged). Quick flash is
available regardless of the camera's drive mode setting. Although the
flash output will be approx. 1/2 to 1/6 of the full output, it is useful for
shooting with a shorter firing interval.
During manual flash photography, this function is available when the
flash output is set to 1/4 to 1/128. Note that you cannot use Quick flash
with the receiver unit during optical transmission wireless shooting.
When the power is turned on, the flash head may automatically operate
(rotate).
When Quick flash is fired during continuous shooting, underexposure
may occur since the flash output decreases.
When the 3/1/o/7/2 timer of the camera is operating, a test
flash cannot be performed.
Set the power switch to <K>.
