2 Important!
Read Before Use
General
– Read this technical manual completely before using the product.
– This technical manual is also available at www.telex.com/aviation.
Health and Safety
– Always keep at least 4 in. (~10 cm) between the ear cups and a pacemaker or implanted
defibrillator because this product generates magnetic fields.
– Keep away from children - product parts and accessories are a choking hazard.
– With ANR (Active Noise Reduction) active, typical aircraft sounds may not sound the
same as when not using ANR. Before operating in an aircraft, verify ANR is active and you
can hear and recognize sounds properly. Set the volume to a safe level that does not
diminish your hearing of alarms and warnings.
– This headset is capable of producing sound pressure over 85 dB (A). In many countries,
this is the maximum legal level for continuous noise exposure during the working day. To
prevent hearing damage, do not listen at high volume levels for extended periods of time.
Preventing Damage and Malfunctions
– Always keep the headset dry and do not expose it to extreme temperatures to avoid
corrosion or deformation.
– Never attempt to repair a headset which is not operating correctly. Contact the Telex
dealer you purchased the headset through or an authorized repair facility.
– Only replace parts of the headset whose replacement is described within this manual. All
other parts must be replaced by an authorized repair facility.

3 Introduction
The Telex Airman 8+ is a lightweight noise-reducing headset designed specifically for
optimizing pilot communications in commercial and business turbine aircraft. Building on the
tradition of the Airman 850 and the Airman 8, Airman 8+ has improved durability, intelligibility,

market and one of only three FAA TSO C139a approved ANR headsets to utilize Telex’s
proprietary battery-free system. Soft pliable ear cushions and headband pads combine with
dual direction ear cup pivots to provide long flight wearing comfort.
– Flexible boom-mounted, noise-reducing microphone that can be positioned for right or
left-side use.
– Lightweight, battery-free ANR with onboard fail-safe to ensure constant communication.
– Soft, pliable ear cushions and headband pads.
– Stainless steel headband and pivot points for superior durability.
– FAA TSO C139a approved.
