Choose how long the camera displays remain on when no operations are performed. Different settings can be chosen for Playback, Menus, Image review, and Standby timer; note that each of these delays is extended by one minute in self-timer mode. Standby timer determines how long the monitor or viewfinder display remains on when no operations are performed during shooting (the monitor and viewfinder dim a few seconds before the standby timer expires). Choose shorter power-off delays for longer battery life.
