Functions a
nd use of the SU-800
The SU-800’s auto power-off function and camera’s 
exposure meter-off function
With a camera body that is compatible with TTL auto flash, the SU-800 goes into 
standby mode when the camera’s exposure meter turns off.
Without a camera body, if the SU-800 is not being used for approx. 40 seconds, 
the standby function activates and automatically turns the SU-800 off to 
conserve battery power.
• No indicators are displayed on the LCD panel in standby mode.
• When in standby mode or when the exposure meter is off, the SU-800 comes back on 
again when:
The [ON/OFF] button on the SU-800 is pressed.
The camera’s power is turned on.
