MLX Telephone Tests

If the LEDs, ringer, buttons, switchhook, or display appear not to be working, try the steps below.
1. Pick up the handset.
2. When 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
I
telephone.
On an MLX telephone with a DSS attached, all LEDs light and the phone rings throughout
I
the test.
On an MLX display telephone, the display blanks out and is replaced with a grid of small
I
dots.
3. Press each line/feature button (two LEDs each).
The red and green LEDs should toggle on and off.
4. Press each fixed-feature button that has an LED (Feature, HFAI, Mute, and Speaker).
Each LED should toggle on and off.
Mute and Speaker LEDs may not toggle consistently because they are managed by
the control unit and the telephone.
5. Press each fixed-feature button that does not have an LED (Transfer, Conf, Drop, and Hold)
and each dialpad button.
When you press each one of these buttons, the Message LED should toggle on and off.
6. Press the fixed-feature buttons and the dialpad buttons in the order shown below to turn on all
the LEDs.
a. Volume down
b. Volume up
c. Transfer
d. Conf
e. Drop
f. Hold
g. Dial 123456789*0#
The LEDs should toggle on and off.
7. If the MLX telephone does not have a display, hang up and go to Step 9; if it does, continue
with the next step.
8. To test an MLX display, press each display button.
