THERE IS A LOUD SQUEAL IN THE INTERCOM SYSTEM WHEN THE INTERCOM VOLUME IS TURNED UP
• Check the noisegate on the Wireless Headsets.
• Check for an open mic near headset speakers. Feedback problems are often fixed by turning the Intercom
volume down, moving the mic away from headset speakers, or unplugging a headset when not in use.
• Unplug the headset locations one at a time from the rear of the Intercom Unit until the squeal stops.
• Check the headset configuration for faulty connections or components. See Troubleshooting a Headset
configuration (page 23).
• Check programming for "Mic Mute Checked".
THE RADIO RECEIVE AUDIO IS WEAK
• Check the setting of the radio’s volume control. The radio’s volume should be set at the normal volume for use
with no Intercom system present.
• Verify proper connection to pins 6 & 7 on the Radio Interface Cable.
• Try swapping the Intercom Unit with a known good one (if one is available). If the problem persists, the problem
is in the radio or the Mobile Radio Interface wiring.
• If no fault can be found, then the fault must lie in the Intercom Unit. Contact Firecom for a Return Materials
Authorization (RMA) Number to return the Intercom Unit for repair.
THE RADIO KEYS BUT HAS NO TRANSMIT AUDIO (CARRIER BUT NO AUDIO)
• Check the Tx gain adjustment.
• Check the affected headset location for faulty connections or components. See Troubleshooting a Headset
Configuration (page 23).
• Verify connection of pins 1 & 2 on the Radio Interface Cable and the Radio Interface Port.
• Try swapping the Intercom Unit with a known good one (if one is available). If the problem persists, the problem
is in the Mobile Radio Interface wiring.
• If no fault can be found, then the fault must lie in the Intercom Unit. Contact Firecom for a Return Materials
Authorization (RMA) Number to return the Intercom Unit for repair.
THERE IS A SQUEAL IN TRANSMIT AUDIO
• Check radio programming and transmit audio gain settings.
