programming, forced-idle, or maintenance mode. When an MLX telephone is in test mode, the system considers it busy and therefore not available for use.

If you hang up during any of these procedures, test mode ends automatically.

Keep the following in mind when using the speakerphone:

■If the Mute button is pressed before the Speaker button, the Mute LED cannot be turned off; it winks.

■The Mute and Speaker LEDs remain steady during test mode.

■The pressing of the Mute button is processed within the telephone.

■When the telephone test is originated from the Speaker button, every second press of the Mute button causes the Mute LED to flash off momentarily. Also, both the Mute and Speaker LEDs may occasionally remain on after disconnecting with the Speaker button.

■Press the fixed-feature buttons repeatedly to toggle the LEDs on and off.

To test the basic features of an MLX telephone, follow the steps below:

! Pick up the handset of the telephone you are testing and push an

ICOM button in Key or Behind Switch mode or an SA button in Hybrid/PBX mode.

! When you hear dial tone, dial ￿￿￿￿to activate test mode.

You should hear a steady test tone over the handset and a ring burst over the speaker. The telephone’s red and green LEDs should be on.

! To test the line buttons, press any line button with two LEDs (red and green).

The diagnostic tone should stop, and the LEDs for that button should go off.
