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.

3.Insert the fresh battery into the compartment, aligning the + on the battery with the + on the case.
