Conserving power
Although the handheld battery can operate for a full day without recharging, Trimble
recommends that you do the following to reduce power consumption:
• Set the handheld to automatically turn off when idle. For more information, see
Suspend mode, page 28.
• Set the backlight to automatically turn off when the handheld is idle for a
specified time. For more information, see Backlight, page 48.
• Reduce the brightness setting for the backlight. For more information, see
Backlight, page 48.
• Turn off the integrated Bluetooth or wireless LAN radios whenever you are not
using them. For more information, see Bluetooth wireless connections
explained, page 105 and Connecting to a wireless LAN access point, page 82.
• Disconnect from the integrated GPS receiver when GPS data is not required,
using the application’s Disconnect or Deactivate GPS command. When you
disconnect from GPS, the integrated GPS receiver switches off and stops
drawing power.
Note – Do not disconnect from GPS if you will be reconnecting within about five minutes. A
GPS application can take up to 30 seconds to reactivate the integrated GPS receiver, so
disconnecting to save power can cost time.
Turning on and turning off the handheld
If the screen on the handheld is blank, the handheld is in Suspend mode (see page 28)
or has been shut down. To turn on the handheld, press the
Power key briefly (less than

To turn off the handheld and put the handheld into Suspend mode, press the
Power
key briefly (less than one second).
To completely shut down the handheld, press the
Power key for one second until the
Power menu appears and then tap the
Shutdown button. All running applications are
shut down, and the handheld is completely turned off.
