Getting started
Battery charging
Once you have installed the battery, the screen indicates the battery status
(see table below). If necessary, place the handset in the charger to charge
the battery. For best performance, keep the handset in the charger when not
in use. The battery is fully charged after 16 hours of continuous charging. See
the table on page 155 for battery operating times.
If the screen shows Low battery, you need to charge the battery without
interruption for at least 25 minutes to give the handset enough charge to use
the telephone for a short time. The following table summarizes the battery
charge indicators and actions to take.
