Fixing Telephone Problems

12 Replace the wiring between the module jack field and the telephone to see if there is a wiring problem.

Analog Multiline Telephone Problems

If telephone LEDs and/or ringing tones do not work properly on analog multiline telephones, follow the steps below.

1Move the T/P switch on the left-hand side to the T (test) position.

You should hear tone ringing, and the red and green LEDs on the terminal should flash alternately.

2If the LEDs do not light, replace the telephone with one that works.

If the problem is resolved, go to Step 4.

3 If the LEDs do not light, retest the original telephone.

Plug it directly into the appropriate jack on the control unit, using a cord that is known to be working.

If this resolves the problem, replace the original cord (or local power unit, if used).

4Move the T/P switch to its normal position.

The ringing tone should stop, and the LEDs should be off.

5If any part of the test fails, replace the telephone.

If the time appears on the display but incoming call information does not, move the T/P switch on the side of the telephone to the center position.

Voice Transmission Problems

If the telephone does not receive tones, check the control unit and wiring with a telephone that works.
