Charging the Handset Battery Pack
The batteries need charging when:
•The phone beeps four times when you press P.
•The battery status icon on the screen is only partly displayed.
•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. (You can place the handset face up or face down if the base is on a table; you can place the handset face down if the base is wall- mounted.) The batteries will be fully charged within 10 hours. Once the batteries are fully charged, you need only put the hand- set in the base when the top segment of the battery status icon flashes or remains off.
A fully charged battery maintains standby power for up to 12 days when the Handset Ringer Control switch is set to ON, and up to 21 days when the Handset 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 only Replacement Battery 4051.
•Do not dispose of the battery in a fire. The cell may explode. Check local codes for special disposal instructions.
•Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
•Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause harm.
•Follow the directions in this manual for charging the battery specified for use with this phone.
•Observe proper polarity orientation between the battery and the battery charger.
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. (See illustration below). Place the battery pack into the case, so the wires rest below 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 10 hours. The telephone might operate before that, but for best performance, let the handset batteries charge fully.
