■On multiline telephones, press the Feature button and dial *34*.

MLX Telephone Tests

If the LEDs, ringer, buttons, switchhook, or display appear not to be working, try the steps below.

1Pickup the handset.

2When you hear dial tone, press *00 (the feature access code).

The telephone enters test mode. For some tests, this means the LEDs turn on; for others, it means the phone starts ringing.

This test connects a test tone to the B-channel and sends a repeated ring burst to the telephone.

On an MLX telephone with a DSS attached, all LEDs light and the phone rings throughout the test.

On an MLX display telephone, the display blanks out and is replaced with a grid of small dots.

3Press each line/feature button (two LEDs each). The red and green LEDs should toggle on and off.

4Press each fixed-feature button that has an LED (Feature, HFAI, Mute, and Speaker).

Each LED should toggle on and off.

NOTE:

Mute and Speaker LEDs may not toggle consistently because they are managed by the control unit and the telephone.
