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 charging. 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.
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
1Remove the battery case cover on the handset by pressing on the indentation and sliding the cover downward.
2Lift out the old battery pack and unplug it from the handset.
3Hold 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.
4Replace the cover by sliding it on its track up over the battery case until it snaps firmly into place.
5The 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.
