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 10 hours . When the
LOW BATTERY light goes on, place the
handset flat in the base.
NOTE: the handset must lie flat in the
base, with the keypad facing down, when
charging.
A fully charged battery, under normal use,
maintains standby power for up to 14 days
when the Handset Ringer Control switch is
set to ON, and up to 21 days when the Hand-
set Ringer Control 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 10 hours of charging, the battery should
be replaced.
CAUTION: To reduce the risk
of fire or injury to persons or
damage to the telephone, read and follow
these instructions carefully.
• Use Replacement Battery 4051 in the
handset.
• Do not dispose of the battery in a
fire. The cell might explode.
• Do not open, puncture or mutilate
the battery. Released electrolyte is
corrosive and might cause damage to
the eyes or skin. It might be toxic
if swallowed.
Replacing the
Handset Battery Pack
1 Remove the battery case cover on
the handset by pressing on the inden-
tation and sliding the cover down
ward.
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 10 hours. The
telephone might operate before that,
but for best performance, let the
handset batteries charge fully.
