Note:
Do 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
disconnecting to save power can cost time.
2.3 Turning on and turning off the handheld
If the screen on the handheld is blank, the handheld is in Standby mode, Battery Charge
mode or has been shut down. To turn on the handheld press the Power key briefly (less than
one second).
To turn off the handheld and put the handheld into Suspend mode press the Power key
briefly (less than one second). The handheld is placed in a very low power state but the
Bluetooth and wireless cellular modem radios may remain active.
To completely shut down the handheld press the Power key for one second until the Power
menu appears and then tap Shutdown. All running applications are shut down, and the
handheld is completely turned off.
Standby mode
When you press the Power key to turn off the handheld, the handheld goes into Standby
mode. This is a low-power mode that maintains the main memory contents and keeps
applications running but does not allow you to operate any of the functions of the handheld:
the handheld is apparently off. The integrated GNSS receiver is turned off and any
application using GNSS is disconnected. If a wireless radio is turned on (the LED is flashing),
the Wi-Fi radio will be turned off, and the Bluetooth and wireless cellular modem radios will
remain turned on. The handheld is capable of receiving data via Bluetooth or the cellular
modem radio while it is in Standby mode. The handheld is able to automatically wake up to
calendar alarms if it is in Standby mode.
Note:
To save battery power, use the Wireless Manager to turn off the wireless radios before
you place the handheld into Suspend mode.
To turn on the handheld when it is in Standby mode, press the Power key. The handheld is
immediately ready for operation. There may be a delay of up to 30 seconds while the
integrated GNSS receiver and the Wi-Fi radio automatically reactivate.
You can configure the handheld to automatically enter Standby mode when it has been idle
for a specified time. By default, the handheld is set to enter Standby mode if it is not used
for one minute.
To change the time before the handheld enters Standby mode:
1. Tap the title bar of the
Home
or the
Start
screen and then tap. The Power control
appears, displaying the
Battery
tab.
2.
Tap the
