icon will change to a charging icon. Once the handheld is fully
charged, the battery icon will replace the charging icon. See page 33
for a list of handheld status icons.

The handheld can be kept at a full charge by “topping up” the
battery every day for 10-15 minutes. From an empty battery, a full
charge can be achieved in approximately 3 hours. It is not necessary
to drain the battery completely before recharging.

If the battery level becomes too low, the signal strength bars (located
in the top right corner of the Home screen, next to the battery icon)
will be replaced by “BAT”. This is an indication that it is time to
recharge the handheld. In this state, all radio functions, such as
sending and receiving email, will be disabled until the battery is
recharged.

When you receive your handheld, you must first insert it into the
charging cradle and allow it to charge to full battery power. (You
can view the strength of the battery in the top right corner of the
Home

 screen.) See page 48 for more information on connecting your

handheld to your PC.
