INSTALLING THE BATTERY
You need one 9-volt battery (not supplied) to protect the module’s mem-
ory if power fails. We recommend an alkaline battery, such as Ra-
dioShack Cat. No. 23-553.
Note:
You must also connect the supplied AC adapter to use the mod-
ule.
Follow these steps to install the battery.
1. If the phone lines are already
connected, unplug them from
the module.
2. Use a coin to turn the lock on
the bottom of the module to
OPEN
, then slide off the battery
compartment cover.

compartment, aligning the + on
the battery with the

case.
