SETTING THE DIALING MODE

Set P∙ ∙T on the back of the base for the type of service you have. If you are not sure which type you have, once the battery is charged, do this test.

1. Set P∙ ∙T to T (tone).

2.Lift the handset, press LINE 1 and listen for the dial tone.

3.Press any number other than 0.

Note: If your phone system requires that you dial an access code (9, for example) before you dial an outside number, do not press the access code either.

If the dial tone stops, that line has tone service.

If the dial tone continues, that line has pulse service.

4.Press LINE 2, listen for the dial tone, and repeat Step 3.

If you have tone service on both lines, leave P∙ ∙T set to T.

If you have pulse service on either line, set P∙ ∙T to P.
