Maintenance; Troubleshooting - Firecom 4100 Operation Manual

General maintenance is required on your 4100 Portable Intercom System.
• It is recommended that you inspect all cables for damage and wear after every use.
• Clean dirt and debris out of intercom, headset ports, and connectors after working in hazardous areas.
Inspect for damage or corrosion. Intercom port covers should remain closed when cables are not attached to
protect from damage or corrosion.
• Check headset cables, earphones, and microphone boom assemblies for damaged or worn parts. See your
headset manual for individual headset care.
Problem: Intercom will not function
• The battery may not be charged. The unit must be fully charged after purchase. See Charging the Battery in
this manual.
• Confirm that the power switch is on.
Problem: There is no sound on the headset
• Check the volume control on the headset and the front panel of the main unit.
• Disconnect, inspect, and reconnect cable connections on the headset and intercom. Inspect for damaged or
corroded pins.
• Check to see if the mute button is depressed.
Problem: You can hear others on the headset but they can not hear you

dead, connect the main unit to the charger to see if it will go into a charge mode. If the battery charger does
not go into charge mode in one hour, and then in float mode in 24 hours, the battery is unrecoverable. See
