PREPARATION
INSTALLING BATTERIES
Your system uses two AAA batteries to maintain information in memory during power failures. For the longest operation and best performance, we recommend you use alkaline bat- teries such as RadioShack Cat. No.
Cautions:
•Use only fresh batteries of the recommended size and type.
•Do not mix old and new batteries, different types of bat- teries (standard, alkaline, or rechargeable), or recharge- able batteries of different capacities.
•When you replace the batteries, have fresh batteries on hand before you begin. You must install fresh batteries immediately after removing the old batteries; otherwise, you might lose the information stored in the system.
•When you replace the batteries, do not press any but- tons on the system after you remove the old batteries. Doing so might erase all stored information from the sys- tem.
•Never leave dead or weak batteries in the system. Bat- teries can leak chemicals that can destroy electronic cir- cuits.
•Dispose of old batteries promptly; do not bury or burn them.
