Note – The life of the battery can be significantly shortened if power is constantly supplied to the handheld. To
avoid this issue, connect the handheld to an external power source only when the battery requires charging.
Once fully charged, disconnect the external power source and allow the battery to discharge through normal
use.
Turning the handheld on and off

To completely shut down the handheld, press and hold the Power button until the Power menu
appears, and then tap Shutdown. All running applications are shut down, and the handheld is
completely turned off.
Note – You can also use the Power menu to put the handheld into Vibration mode or Airplane mode.
Checking the level of battery power
To check the level of battery power remaining at any time while the handheld is on:
1. On the Home screen or the Start screen, tap the title bar, then tap the battery icon.
2. The Battery tab shows the battery status and battery level.
Conserving power
The Lithium-ion polymer battery life is dependent upon the application and operating environment.
For example, estimated battery life for a new battery is approximately 12 hours with the device
turned on but idle, backlight at 15% and all radios and compass off.
Trimble recommends that you do the following to reduce power consumption:
l Set the handheld to automatically turn off when idle. For more information, see Adjusting the
display and keypad brightness, page 48.
l Reduce the brightness setting for the backlight. For more information, see Adjusting the
display and keypad brightness, page 48.
