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.
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.
