PREPARATION
INSTALLING BATTERIES
Your telephone uses two AAA batteries
(not supplied) for power to retain the
numbers you store in memory. For the
best performance and longest life, we
recommend alkaline batteries, such as
Cat. No. 23-555.
Cautions:
Always use fresh batteries of the
required size and recommended
type.
Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
1. Use a Phillips screwdriver to loosen
the screw in the battery compart-
ment cover on the bottom of the
telephone, then lift open the cover.
2. Put the batteries into the compart-
ment as indicated by the polarity
symbols (+ and –) marked inside.
3. Close the cover and tighten the
screw.
4. Be sure the
NORM/STORE BATT
TEST
switch on the back of the
phone is set to
NORM
(see “Testing/
Replacing the Batteries”).
Testing/Replacing the Batteries
To test the batteries’ strength at any
time, temporarily slide
NORM/STORE
BATT TEST
(on the back of the tele-
phone) to
STORE BATT TEST
.
If the BATT TEST indicator does not
light or is dim, replace the batteries.
