9.4 Replacing Your Battery

Your EP4300 telephone uses AC power from a standard 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 auto-

matically switches to battery operation for approximately two hours. When the

power is restored, the telephone automatically 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 static memory that

retains its contents without electricity.

Please note that it is not necessary for you to install batteries in your EP4300 tele-

phone 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. You may wish to install batteries in at least one EP4300

phone for emergency operation, or have another standard phone available.

Note: The only purpose of having batteries installed is so that the telephone itself

can function for up to a few hours in the event of a power failure. After batteries

installed and the telephone on idle state, the batteries can use one year.

If you do choose to install batteries in your EP4300 telephone, we recommend only

the use of alkaline 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 connect-

ed, that does not require battery power, so that you are always sure to have use of

a telephone during a power failure.
