PREPARATION

INSTALLING BATTERIES

You need four AAA batteries (not supplied) to protect the sys-
tem’s memory during a power failure. For the longest operation
and best performance, we recommend alkaline batteries, such
as RadioShack Cat. No. 23-558.

Cautions:

• Always use fresh batteries of the required size and rec-

ommended type.

• Do not mix old and new batteries, different types of batter-

ies (standard, alkaline, or rechargeable), or rechargeable
batteries of different capacities.

Follow these steps to install batteries.

Notes:

• When you replace the batteries, do not press any buttons

on the system after you remove the old batteries. Doing
so could erase all stored information.
