RCA 29878 User Manual

In the event of a power loss, a 9-volt alkaline battery (not included) enables
the answerer to retain messages stored in memory. To install the battery:

1. Remove the battery compartment door on the bottom of the unit by

loosening the screw with a Phillips screwdriver. Lift the door.

2. Connect a fresh 9-volt alkaline battery (not included).  The large and

small contacts on the battery clip and the battery will interlock. Once
connected, place the battery inside the battery compartment.

3. Replace the battery compartment door and tighten the screw.

 If the battery is low or not installed, the unit announces “Low Battery ”

at the end of your messages.

If you’re not going to use the unit for more than 30 days,

remove the batteries because they can leak and damage the unit.
