• If the CHARGE/IN USE indicator does not light when you
place the keypad on the base, be sure the battery pack and
AC adapter are correctly and securely connected. Also,
check the charging contacts on the keypad and base. If the
contacts are dirty or tarnished, clean them with a pencil
eraser.
• If the battery pack becomes completely discharged or the
base loses power while the keypad is away from it, place the
keypad on the base for about 5 seconds to reset the security
access-protection code. If the keypad loses power, leave it on
the base to charge the battery pack.
• If you are not going to use your phone for an extended period
of time, disconnect its battery pack. This helps increase the
battery pack’s life.
• When the keypad is on the base, the CHARGE/IN USE indi-
cator lights even when the battery pack is not connected. If
your phone does not work, be sure the battery pack is prop-
erly connected.
The supplied battery pack should last about a year. If the battery
pack does not hold a charge for more than 2 hours after an over-
night charge, replace it with a new 3.6-volt, 600 mAh battery pack
with a connector that fits the socket in the battery compartment.
You can order a replacement battery pack through your local Ra-
dioShack store.
Note: To avoid losing numbers stored in memory, you must install
and begin charging the new battery pack within 2 minutes of re-
moving the old one.
Warning: Dispose of the old battery pack promptly and properly.
Do not burn or bury it.
