Use ON/OFF Power Switch to power the flash unit on or off. Turn off

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 60
minutes (adjustable, 30 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, Page 45)

default. Another option “30 minutes” is available.
