PROBLEM

ITEMS TO CHECK

I DO NOT HEAR A

DIAL TONE WHEN I

TRY TO MAKE OR

RECEIVE A PHONE

CALL.

If you are using batteries, confirm that they

are good and placed in the battery compart-

ment correctly.

If you are using an AC Power Supply, confirm

that it is plugged in and the power outlet is

turned on.

Confirm that the Headset /Handset Selector

switch is depressed (colored indicator showing).

Confirm that you have lifted the telephone

handset out of the cradle.

Confirm that the telephone handset cable and

the short curly pigtail to the telephone are con-

nected to the correct jacks. (see "Installation”)

Confirm that the Telephone/Amplifier

Compatibility Switch is in the correct setting for

your phone (see “Set the Telephone/Amplifier

Compatibility Switch” on page 5). You may

want to try moving the switch through all of

the positions until you hear a clear dial tone.

Experimenting with various switch settings will

not harm the amplifier or your phone.
