Charging the battery
Charge the battery in the handheld (see page 29). To charge the battery, do one of the
following:
• Connect the AC power adaptor to the Power socket on the handheld and then
connect the adaptor to mains power. An international adaptor kit is provided
with the handheld.
• Connect the optional vehicle power adaptor to the Power socket on the
handheld and then connect the adaptor to the vehicle power source.
When the handheld is connected to a power source, the battery icon in the Today
screen changes to . Fully charging the battery from empty takes approximately four
hours. You can use the handheld while it is charging.
Note – You can only use the USB cable (connected to a computer) to provide a minimal
charge to the battery; the battery must have enough power to turn on the Juno series
handheld and form an active connection to the computer. To fully charge the battery, use
the AC or vehicle power adaptor.
The Power LED beside the Power key on the handheld indicates the battery power or
charging status, as shown below:
Avoid keeping the battery at full charge at high temperatures. For more information,
see Storage, page 20.
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 requries charging. Once fully charged, disconnect the external power
source and allow the battery to discharge through normal use.
