You can configure options to conserve power usage.
Power management option
Dim Display (Backlight) timer
Suspend timer
Shut Down timer
When the AC adapter is connected to the power module, all the timers are disabled. It is
recommended to connect your Trex unit to the AC Adapter when not in use to ensure full
charge of the power module and maximize the life of the battery.
Note
The timers are cumulative. For example, if you set the Dim Display (Backlight) timer to 5
minutes, the Suspend timer to Never, and the Shut Down timer to 10 minutes, the Trex
unit shuts down after 15 minutes of inactivity.
Enter or exit suspend mode
Suspend mode is similar to standby mode on a phone. The screen is turned off, but all
connectivity is maintained. If the Trex unit is powering a device before entering suspend, it
continues to power and communicate with the device. If a Trex unit is connected to a
network, it remains connected in suspend mode. You can put the Trex unit in suspend
mode, or wait for the suspend timer to expire.
When in suspend mode, the Trex unit shuts down if there is no activity (key presses) after a
specified amount of time. Use the Turn off after option on the Power Management
screen to specify this time.
Procedure
1. To enter suspend, do one of the following:
• Quickly press the power button, and then tap Suspend.
Tap Settings or the status bar at the top of the screen, and tap More → Power
•
Management → Suspend.
