BATTERIES
Charging the
Handset Battery Pack
The batteries need charging when:
• The phone beeps four times when you
press P.
• The LOW BATTERY light on the
handset flashes on and off.
• The phone does not respond when you
press P, and no lights go on.
Place the handset in the base so the
CHARGING light goes on. The batteries will
be fully charged in 14 hours.
NOTE: The handset must lie flat in the base,
with the keypad facing down, when charg-
ing. The charging light in the base goes on if
the handset is positioned correctly.
A fully charged battery maintains standby
power for up to 14 days when the Handset
Ringer ON/OFF switch is set to ON, and up
to 21 days when the Handset Ringer ON/OFF
switch is set to OFF.
If it’s more convenient for you, you can leave
the handset in the base all the time.
It is impossible to overcharge the batteries.
If you get a low battery indicator even after
the batteries have been charged 14 hours, the
battery should be replaced.
Replacing the Handset
Battery Pack
1 Remove the battery case cover on
the handset by pressing on the
indentation and sliding the cover
downward.
2 Lift out the old battery pack and
unplug it from the handset.
3 Hold the new battery pack and plug
the connector into the handset.
Place the battery pack into the case, so
the wires rest above the battery pack.
4 Replace the cover by sliding it on its
track up over the battery case until it
snaps firmly into place.
5 The new batteries must be charged
before using the phone. Place the
handset face down in the base and
allow it to charge for 14 hours. The
telephone might operate before that,
but for best performance, let the
handset batteries charge fully.
