The lines in the display report the following information:

• First line—TX Matrix Plus router name.
• Second line—Length of time the TX Matrix Plus router has been running, reported in the following form:

Alarm Cutoff/Lamp Test Button

The alarm cutoff/lamp test button labeled ACO/LT is located below the alarm LEDs.

Figure 4 shows the alarm cutoff button.

Figure 4: Alarm Cutoff/Lamp Test Button

Use the ACO/LT button to deactivate the red and yellow alarms. Pressing the button turns off both LEDs and deactivates the device attached to the corresponding alarm relay contact on the TXP-CIP. However, the LCD continues to report the alarm message until the condition that caused the alarm is cleared.

To test the LEDs on the craft interface, press and hold the ACO/LT button. All the LEDs on the craft interface should light.
