To conserve power, set the shut down timer to automatically shut down the Trex unit after a period of inactivity, such as no key presses or taps on the screen.
The timer is enabled only when the AC adapter is not connected to the Trex unit.
Note: The timers are cumulative. For example, if you set the Dim
Display (Backlight) timer to 5 minutes, the Suspend timer to 5 minutes, and the
Shut Down timer to 5 minutes, the Trex unit enters suspend after 10 minutes and
shuts down after 15 minutes of inactivity.
