Power Management
Use ON/OFF Power Switch to power the flash unit on or
off. Turn off if it will not be used for an extended period of
time. Setting as a master flash, it will turn the power off
automatically after a certain period (approx. 90 seconds)
of idle use. Pressing the camera shutter halfway or
pressing any flash button will wake up the flash unit.
Setting as a slave flash, it will enter sleep mode after a
certain period (adjustable, 60 minutes by default) of idle
use. Pressing any flash button will wake it up.
Disabling Auto Power Off function is recommended
when the flash is used off camera. (C.Fn-APO)
Slave Auto Power Off Timer is set to 60 minutes by
default. Another option "30 minutes" is available. (C.Fn-
Sv APOT, Page 42)
