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 for approxi- mately two hours. When the power is restored, the telephone automatically switch- es 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.

Install three 1.5V size AA alkaline batteries in the battery comparment

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 for up to two hours in the event of a power failure. You may wish to install batteries in at least one Epic phone for emergency opera- tion, 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.
