20 Juno Series Handhelds User Guide
Conserving power
Although the handheld battery can operate for a full day without recharging, Trimble
r
ecommends 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 21.
• Set the backlight to automatically turn off when the handheld is idle for a
specified time. For more information, see Backlight, page 37.
• Reduce the brightness setting for the backlight. For more information, see
Backlight, page 37.
• Turn off the integrated Bluetooth or Wi-Fi radios or cellular modem whenever
you are not using them. For more information, see Turning on and turning off
the integrated radios, page 48.
• Disconnect from the integrated GNSS receiver when GNSS data is not required,
using the application’s Disconnect or Deactivate GNSS command. When you
disconnect from GNSS, the integrated GNSS receiver switches off and stops
drawing power.
Note – D
o not disconnect from GNSS if you will be reconnecting within about five minutes.
A GNSS application can take up to 30 seconds to reactivate the integrated GNSS receiver,
so di
sconnecting to save power can cost time.
