5. Headsets and Intercom
5.1. For All Headset Issues Check the Following
5.1.1. Confirm System is in Normal Mode
1. Power is on.
2. Control panels are active and functioning.
3. System is not in Emergency Mode.
5.1.2. Confirm headsets are set up correctly:
1. Confirm headset is securely connected to the headset jack.
2. If a dropcord is used, confirm headset is securely connected to dropcord and dropcord
securely connected to aircraft connector.
3. Ensure volume controls on headset and dropcord are at maximum.
4. If noise-cancelling headsets are used, ensure headset has power from a fresh battery pack or
aircraft power. This is usually a separate breaker to the audio system.
5. Try using other headsets and dropcords.
5.2. No Earphone Audio of any kind at Headset
1. If the system has an “Earphone Disable” switch or other mechanism for disabling audio to the
headsets through the system configuration, ensure all such mechanisms are deselected.
2. Ensure all Transmit PTTs on aircraft controls and dropcords are deselected, as transmit may
be programmed to mute receivers and ICS.
3. Confirm continuity of Earphone Audio from headset jack to router headset connector. Check
connectors at both ends and any disconnects for damage, corrosion, or pins pushed back.
4. If continuity is confirmed, then the router may have a configuration issue or a fault. Contact
Eagle Technical Support for further on-aircraft tests before returning the router for servicing.
5.3. No Mic Audio of any kind from Headset
1. Ensure no mic disconnect on the dropcord or aircraft controls is selected, as this will prevent
ICS and transmit sidetone from working correctly.
2. Confirm continuity of Mic Audio from headset jack to router headset connector. Check
connectors at both ends and any disconnects for damage, corrosion, or pins pushed back
3. If continuity is confirmed, then the router may have a configuration issue or a fault. Contact
Eagle Technical Support for further on-aircraft tests before returning the router for servicing.
5.4. Radio Receive / Transmit OK, but no ICS at Headset
5.4.1. Check for All ICS Issues
1. Confirm the ICS knob on the control panel responsible for that headset is OUT.
2. Confirm ICS volume is at midpoint.
3. Confirm ICS Isolate is off and ICS Private functions are disabled.
4. Key intercom through ICS Keyline or turning VOX pot fully clockwise.
5.4.2. Cannot Transmit on ICS
1. Set the controls as described in Section 4.4.1.
2. Confirm the mic you are attempting to key ICS on is not also keying a radio. ICS is disabled
when transmitting on a radio.
3. If the ICS works when the drop-cord ICS keyline is keyed, but not on VOX, then the drop cord
may disconnect the mic line except when a keyline is pressed. Confirm continuity of the mic
hi and lo when the drop-cord is unkeyed.
