    What to do if I hear others only sporadically or the sound is distorted and unintelligible on my Telex Headsets?
    • W
      William CraigJul 27, 2025
      If you hear others only sporadically, or the sound is distorted and unintelligible on your Telex Headsets, try the following: Check and clean the connectors, then reconnect them to the aircraft. Reposition the headphones to ensure they properly cover your ears. Also, replace the ear cushions if they are missing or need replacement. If the issue persists, an authorized avionics technician needs to verify the compatibility and proper function of the intercom system. Adjust the headphone volume as needed. If none of these steps work, the headphones may not be functioning and should be returned to an authorized repair center for maintenance.

    Why do others only hear me sporadically or my voice is distorted and unintelligible on my Telex Airman 8?

      If others only hear you sporadically or your voice is distorted and unintelligible when using Telex Headsets, try repositioning the microphone close to the front of your mouth. Replace the windscreen if it’s missing or needs replacing. Adjust your speaking level to avoid speaking too loudly or quietly. If these steps don't resolve the issue, an authorized avionics technician needs to verify the intercom system's compatibility and function, and readjust the microphone amplifier. If the microphone is still not functioning properly, return the headset to an authorized repair center for maintenance.

      If no one can hear you when you talk using Telex Headsets, first ensure the microphone is correctly plugged in and the cord isn't damaged. Then, reposition the microphone close to the front of your mouth. If the problem persists, an authorized avionics technician needs to verify the compatibility and proper function of the intercom. It may also be necessary for a technician to readjust and re-test the microphone amplifier. If the microphone isn't functioning, return the headset to an authorized repair center for maintenance.

    What to do if I cannot hear anyone who is trying to speak to me using Telex Airman 8 Headsets?

      Terry WilsonAug 15, 2025
      If you cannot hear anyone speaking to you through your Telex Headsets, first verify the headphones are correctly plugged in and that there are no breaks or damage to the cord. Ensure the headphones are properly positioned, fully covering your ears. An authorized avionics technician needs to verify the intercom system's compatibility and proper function. Adjust the headphone volume. If you still cannot hear, the headphones may not be functioning and should be returned to an authorized repair center for maintenance. If you cannot hear yourself, adjust the sidetone level on the intercom or radio system, if applicable, as the headset does not control sidetone levels.

    Why are my Telex Airman 8 oscillating, creating unexpected noise, or only blocking background noise intermittently?
    • D
      David HobbsAug 21, 2025
      If your Telex Headsets are oscillating, creating unexpected noise, or only blocking background noise intermittently, ensure that the microphone or XLR connector power source is working by consulting an authorized avionics technician. Verify the connectors are clean, undamaged, and fully inserted. Check that the ear cushions are correctly installed or replace them if damaged. Make sure the ear cups are properly positioned on your ears. If the issue persists after these checks and power verification, return the headset for repair. Contact Bosch customer service to check for any known compatibility issues with the connected aircraft.

    How to fix Telex Airman 8 that are not blocking background noise?
    • J
      Jacob HarrisonNov 5, 2025
      If your Telex Headsets are not blocking background noise, ensure the ANR power switch is in the 'on' position. Check that the headset connectors are clean and properly connected to the aircraft. Verify with an authorized avionics technician if the microphone is constantly powered or if power is correctly present on the XLR connector. Check the ear cushions are properly installed or replace them if damaged. Ensure the ear cups are correctly positioned on your ears. If the issue continues after these steps, and after verifying all proper connections and power, return the headset for repair. Contact Bosch customer service to determine if there are any known compatibility issues. Finally, verify with an authorized avionics technician that all grounding of avionics systems is connected properly...
