Charging the battery

When fully charged, the handheld battery provides enough power for 9 hours using

GPS and with the backlight on at the default settings. When not using GPS, but with

the backlight on at the default settings, the battery provides enough power for up to 15

hours.

Charge the battery in the handheld (see page 26). To charge the battery, do one of the

following:

• Connect the AC power adaptor to the Power 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, the

AC or vehicle power adaptor must be used.

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 18.

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.
