Battery installation & charging
Install the battery as shown below. Once you have installed the battery, the
screen indicates the battery status (see table below). If necessary, place the
handset in the telephone base or 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 the
Technical specifications page in the user’s manual for battery operating times.
If the screen is blank, you need to charge the handset without interruption for
at least 10 minutes to give the handset enough charge to use the telephone
for a short time. The screen shows LOW BATTERY and the backlight is off until
you have charged the battery without interruption for at least one hour. The
following table summarizes the battery charge indicators and actions to take.

securely into the socket
inside the handset battery
compartment, matching the
color-coded label. Insert
the supplied battery with
the label THIS SIDE UP
facing up as indicated.

then slide it upwards until it
