Preparation
Your module’s display is protected by a piece of plastic film dur-
ing shipment. Peel off this film before you use the module.

INSTALLING BATTERIES

Your module requires four AAA batteries (not supplied) to pro-
tect its memory during a power failure. F or the best perfor-
mance and longest life, we recommend RadioShack alkaline
batteries.
Cautions:
• Use only fresh batteries of the required size and recom-
mended type.
• Do not mix old and new batteries or different types of bat-
teries (standard, alkaline, or rechargeable), or recharge-
able batteries of different capacities.
• When you replace the batteries, do not press any buttons
on the module after you remove the old b atteries. Doing so
could erase all stored information.
• When replacing the batteries, have fresh ones on hand
before you begin. If you do not install the new batteries
within about 2 minutes after removing the old ones, you will
lose all the information stored in the module.
Follow these steps to install batteries.
1. If you are replacing batteries, unplug the module from the
telephone line, the telephone, and AC power. Unplug both
modular line cords from the back of the module.
