INSTALLATION
Open the battery door on the base of the unit
and install one 9 V battery. The battery is used
to save your messages in the event of a power
failure. Your announcements and messages will
be retained in memory for at least 50 hours
during a power failure. If the battery used for
backup power is missing, low on power, or
incorrectly installed, the Message window
displays ”Lo”.
Notes:
To avoid losing your announcements or mes-
sages stored in memory, you should leave the
unit connected to the AC power while changing
the battery. Disconnect the telephone line cord
before changing the battery.
Batteries are hazardous waste. Do not dispose
them together with the household garbage.
