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 29.
• Set the backlight to automatically turn off when the handheld is idle for a
specified time. For more information, see Backlight, page 47.
• Reduce the brightness setting for the backlight. For more information, see
Backlight, page 47.
• Turn off the integrated Bluetooth or wireless LAN radios or cellular modem
whenever you are not using them. For more information, see Turning on and
turning off the integrated radios, page 76.
• 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.
