Charging the Handset Battery Pack
The handset batteries need charging when:
• The handset beeps four times when you press P.
• The low battery symbol is visible on the display on the handset.
• 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 four hours. Once the batteries are fully
charged, you need only put the handset in the base when the PWR
RESERVE BATT LOW light flashes.
If it is 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
signal even after four hours of charging, the battery should be replaced.
Replacing the Handset Battery Pack
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 might explode. Check
with 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.
• Charge the battery provided with or identified for use with this product
only in accordance with the instructions and limitations specified in this
manual.
• Observe proper polarity orientation between the battery and battery
charger.
To replace the handset battery pack:
1 Remove the battery compartment 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 cord into the handset. Place
the battery pack in the compartment so the cords rest on top of the
battery pack.
4 Replace the cover by sliding it on its track up over the battery
compartment until it snaps firmly in place.
5 The new batteries must be charged before using this telephone. Place
the handset in the base unit and allow it to charge for four hours.
The telephone may operate before that, but, for best performance, let
the batteries charge fully.
