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.
