Additional Information
Replacing Your Battery
Operation During a Power Failure
Your EPIC telephone uses AC power from a
standard wall outlet. As long as the tele-
phone is connected to a wall outlet, it will
operate using the AC power. Please remem-
ber to plug your telephone into a wall out-
let 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 on line 1 only for
approximately twelve hours. When the power
is restored, the telephone automatically
switches back to AC power and resumes nor-
mal operation. If the battery is missing or low
on power when AC power is lost, the tele-
phone will not function. However, all feature
settings and memory numbers will be main-
tained, since they are stored in a static mem-
ory that retains its contents without electricity.
Please note that it is not necessary for you to
install batteries in your Epic telephone for it to
function normally. In fact, batteries are not even
needed 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
memory which retains its contents even with no
electrical power. The only purpose of having
batteries installed is so that the telephone itself
can function on line 1 only for up to twelve hours
in the event of a power failure. You may wish to
install batteries in at least one Epic phone for
emergency operation, or have another standard
phone available.
If you do choose to install batteries in your Epic
telephone, we recommend only the use of alka-
line batteries. Also, please make sure to install
the batteries 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.
