• If using aircraft power, check the aircraft fuse or circuit
breaker. The LED should be lit.
• If using battery power, ensure that the battery is fresh and
correctly installed.
• Check that the LED is lit. (A blinking green LED indicates
a good battery. A steady red LED indicates a low battery.)
• Check to see if the volume controls are set too low. (See
Volume Control for method of adjusting volume.)
• Check the volume setting of intercom/radio.
• Check the headset aircraft connection.
• Check the ports at the outside surface of each earcup to
ensure they are not blocked. If dust or dirt is present,
carefully remove the debris using tweezers. Do not
vacuum or blow out debris.
• Check to see if the volume control is set too low. (See
Volume Control for method of adjusting volume.)
• If using with a monaural aircraft audio system, verify
that the stereo/mono switch is set to mono.
• If plugged into a monaural system with the switch set to
stereo, you will hear only through the earcup to which
the cable is attached. Set the switch to mono.
• Check to see if the protective inner screen is damaged.
