TROUBLESHOOTING A HEADSET LOCATION
This procedure will help determine if a problem exists in a particular headset location, and
which component in the headset location is faulty.
1. Examine the headset’s label to determine if the headset is an Intercom-Only Headset
or a Radio-Transmit Headset.
• If the headset is a FH-10 or a UH-10, it is a Radio-Transmit headset. The
speakers should always be active. The mic should always be active for intercom
communication and pressing the Red PTT button on the ear dome should key the
radio for radio transmission.
• If the headset is a FH-20 or a UH-20, it is an Intercom-Only Headset. The
speakers should always be active. The mic should be active for intercom
communication only when the Black PTT button on the ear dome is pressed.
The headset should never cause the radio to key.
• If the headset is a FH-40 or a UH-40, it is an Intercom-Only Headset. The
speakers should always be active. Pressing the Yellow PTTontheeardome
will activate the mic for intercom communication. The mic will remain active
until the Yellow PTT is pressed again.
2. Plug the headset into another good headset location.
• If the headset fails to perform properly in the new location, the headset is faulty.
Contact Firecom Service for a Return Material Authorization (RMA) Number to
return the headset for repair.
.
3. Unplug the CA Cable from the intercom unit and exchange intercom ports with a
known good headset location.
• If the headset location works properly, check the intercom port for bent or stuck
pins which can be straightened.
• If the headset fails to perform properly, the headset location has a faulty
component and you should continue troubleshooting the headset location.
4. Check the HM-10 by exchanging it with a known good one.
• If the new HM-10 works, check the RJ-12 Modular Jack of the faulty HM-10 for
bent or stuck pins. If the pins look good and the HM-10 fails to perform
properly, it will need to be replaced.
5. Install new RJ-12 Modular Plugs on BOTH ends of the CA Cable (page 28).
6. Replace the CA Cable.
