TROUBLESHOOTING A HEADSET CONFIGURATION
This procedure will help determine if a problem exists in a particular headset configuration, and which component in the
headset configuration is faulty.
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 51 Series FH or UH model, 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 will key the radio for radio transmission.
• If the headset is a 52 Series FH or UH model, 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 54 Series FH or UH model, it is an Intercom-Only Headset. The speakers should always be
active. Pressing the Yellow PTT on the ear dome will activate the mic for Intercom communication. The mic will
remain active until the Yellow PTT is pressed again.
Plug the headset into another good headset configuration.
If the headset fails to perform properly in the new configuration, the headset is faulty. Contact Firecom Service
•
for a Return Material Authorization (RMA) Number to return the headset for repair.
Unplug the CA Cable from the Intercom unit and exchange Intercom ports with a known good headset configuration.
• If the headset configuration works properly, check the Intercom port for bent or stuck pins which can be
straightened.
If the headset fails to perform properly, the headset configuration has a faulty component and you should
•
continue troubleshooting the headset configuration.
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.
Install new RJ-12 Modular Plugs on BOTH ends of the CA Cable (page 21).
•
Replace the CA Cable.
