Advisory
Please read the information in this user manual carefully
before using your headset. Your aircraft sounds such as engines,
propellers, and warning alarms may sound differently when using a
new headset. When using your AC-50 headset, please limit the
volume to safe levels to ensure you are able to hear
communication and warning alarms from your aircraft.
Do not attempt to disassemble or service the headset. This will void
your warranty and may result in unexpected damage to your
headset.
