Notes:
• If AC power fails or if the AC adapter is disconnected, the module
automatically tests the battery each time it receives a new call.
When appears on the display or the display dims (even after
you restore power), replace the battery.
• You must install a fresh battery within 5 seconds after you remove
the old one. Otherwise, you might lose the information stored in the
module.
Follow these steps to install or replace the battery.
1. If the phone lines and AC adapter are already connected, unplug
them from the module.
