Replacing Batteries

Change the batteries when the sound becomes garbled or slows
down, or when pressing a button does not trigger a response from
the unit.
You will also need to replace the 2 "LR44" back-up batteries from
time to time. These batteries maintain your clock and time settings
should the regular batteries lose power and/or when you are
replacing the regular batteries.
To replace back-up batteries:
The back-up battery compartment is located inside the
battery compartment (under the AAA batteries). Use a small
Phillips screwdriver to turn the screw on the battery door in a
counterclockwise direction to loosen screw. Remove the screw and
open the door. Remove the 2 LR44 batteries. Insert two new LR44
batteries, being careful to match the + and – ends of the batteries
to the diagram inside the battery compartment. Replace the battery
compartment door and insert the screw. Tighten the screw by using
a small Phillips screwdriver to turn the screw in a clockwise direction
until secure. Do not over tighten the screw.
