Turning On The Power Switch - Canon Speedlite 320EX Instruction Manual

Turning on the Power Switch

About Quick Flash
The flash-ready lamp blinks when Quick Flash is ready even before the
flash is fully charged.
You can use the flash to take a picture at that time; however, the flash
output is only half or one-third of the flash's full charge. This is useful for
taking pictures of subjects very close to the flash.
About Auto Power Off
To save battery power, the power will turn off automatically after 90
seconds of idle use. To turn on the Speedlite again, press the camera's
shutter button halfway.
The time until auto power off takes effect may increase when firing
continuous flashes.
Auto power off can also be disabled (p.32).
