Thank you for purchasing your new Puretone NanoComm GA custom aviation headset.
This headset is supplied with two custom-made sets of earpieces for your convenience. The
clear earpieces are straight-through full-concha earpieces that offer approximately 30dB
noise reduction of external sounds, while the signal from the radio is un-hindered. The yellow
earpieces are PROTECThear®filtered earpieces that offer the same level of attenuation of
external sounds, but in addition provide an SNR of 29dB to sounds broadcast via avionics
(see table).
Hold the earpiece with index finger
& thumb with flat side facing away
from the ear.
Place earplug canal into the ear
canal & gently twist backwards until
the earpiece slides comfortably into
the ear bowl.

helix of the ear.
To ensure the correct fit, push gently
on the flat area to seat the earpiece
into the bowl of the ear.
With index finger press on the back
of the earflap to lift the earpiece

Important note: the microphone is

Do’s And Don’ts
Your NanoComm GA has been manufactured to extremely high standards,
however, we recommend that you follow these simple steps to ensure the
headset gives high quality un-interrupted performance for years to come.
Do’s:
Always ensure the white dot shown on the microphone is pointing toward
the mouth. Ensure the mic is placed close to the lips. If the lips lightly
brush the windshield whilst talking then the mic is optimally positioned.
When connecting the headset to the custom-made earpieces, always
ensure this is done in a horizontal direction. Insert one side first then
apply gentle pressure to the other side until an audible click is heard (see
diagram 1.1).
When removing the headset from the custom-made earpieces, always
make sure this is done in an upward (vertical) direction (see diagram 1.2).
When not in use, always ensure the NanoComm GA is packed into the carry
case supplied and not subjected to undue rigours.
Ensure earpieces are cleaned on a regular basis. Earpieces can be cleaned
using regular baby wipes or alcohol swaps, available from a chemist.
NEVER SUBMERGE EARPIECES IN WATER.
Don’ts:
Never remove the plugs from the avionic equipment by pulling on the
wires. Always grasp the plugs firmly before pulling.
Never attempt to disconnect the headset from the earpieces by pulling the
cables only.
Never offer your NanoComm GA to another person to use. The earpieces
are custom-made exclusively for you and will not offer the same level
protection or comfort to anyone else.
