• Keypad button functions do not operate, or the station beeps when a button
is pressed (affected buttons could include “Assign,” “Station,” “Dial,”
“Menu,” and “Swap”).
1. Ensure the function has not been inhibited from the configuration program of
the station’s local Configuration menu.
2. Reset the station.
3. Replace the station.
• The station appears to activate talk paths, but other stations can’t hear the
station operator.
1. Check “Mic On/Off” and “Panel Mic” buttons to ensure the intended
microphone is selected and on.
2. If the correct microphone is turned on, ensure the station audio has not been
muted externally through the logic inputs.
3. Make sure the station has not been defined as a nearby station.
4. Activate the Matrix Loopback mode from the station’s Maintenance menu to
check the audio paths to the matrix.
5. Enable eavesdropping on the station.
6. Test the integrity of the station’s audio path by temporarily setting a forced
listen to it.
7. Reset the station.
8. Replace the station.
• The station is inoperative and all red LEDs flash slowly.
1. Wait 60 seconds. If the matrix frame has just been powered up, it is possible it
is still downloading the configuration to the Matrix cards.
2. Ensure the cable connecting the station to the matrix is plugged in at both
ends.
3. Check the integrity of the data paths, especially the polarity for stations using a
COM-10 communication module.
4. Check the configuration program to ensure the station has been assigned the
correct port type.
5. Confirm the matrix card type matches the station. Stations with COM-10
communication modules should have an MVX-A16.
6. Reset the station’s matrix card in the Matrix frame.
7. Replace the station’s matrix card in the Matrix frame.
8. Reset the station.
9. Replace the station.

4. Check the configuration program and the station’s logic inputs to ensure the
speaker has not been software disabled.
