PREPARATION
INSTALLING BATTERIES
The module requires four AAA batteries for power. For the long-
est operation, we recommend you use alkaline batteries (such
as RadioShack Cat. No. 23-555).
Follow these steps to install the batteries.
1. If the phone line is already connected, unplug it from the
module.
2. Use a flathead screwdriver to remove the screw from the
battery compartment door, then slide off the cover.
