PREPARATION
INSTALLING BATTERIES
This CID requires four AAA batteries (not sup-
plied) to protect its memory when AC power fails
or is disconnected. For the longest life and best
performance, we recommend RadioShack alka-
line batteries.
Cautions:
• Always use fresh batteries of the required
size and recommended type.
• Do not mix old and new batteries, different
types of batteries (standard, alkaline, or
rechargeable), or rechargeable batteries of
different capacities.
Follow these steps to install batteries and pro-
gram the CID.
