Additional Information
Replacing Your Battery
Operation During a Power Failure
Your telephone uses AC power from a stan-
dard wall outlet. As long as the telephone is
connected to a wall outlet, it will operate using
the AC power. Please remember to plug
your telephone into a wall outlet that is not
controlled by a wall switch. If AC power is
disconnected or there is a power failure, the
telephone automatically switches to battery
operation for approximately two hours. When
the power is restored, the telephone automat-
ically switches back to AC power and
resumes normal operation. If the battery is
missing or low on power when AC power is
lost, the telephone will not function. However,
all feature settings and memory numbers will
be maintained, since they are stored in a stat-
ic memory that retains its contents without
electricity.
Please note that it is not necessary for you to
install a battery in your telephone for it to func-
tion normally. In fact, a battery is not even need-
ed to preserve your memory dial numbers in the
event of a power failure. This is because all
memory dial numbers are stored in a static mem-
ory which retains its contents even with no elec-
trical power. The only purpose of having a bat-
tery installed is so that the telephone itself can
function for up to two hours in the event of a
power failure. You may wish to install a battery
in at least one phone for emergency operation,
or have another standard phone available.
If you do choose to install a battery in your tele-
phone, we recommend only the use of an alka-
line battery. Also, please make sure to install
the battery after the telephone has already been
plugged into the AC electrical outlet.
Note: It is recommended that you have at
least one standard telephone connected, that
does not require battery power, so that you
are always sure to have use of a telephone
during a power failure.
