The QuietComfort2™ relies on battery power to
operate, battery failure results in all audio being
lost in the headphones. However, earbuds plugged
into the Auxiliary Audio Jack do not require battery
power and will maintain communications ability.
The UFM microphone is powered by the aircraft
comm panel. In case of QC2 battery failure,
transmit abilities are maintained.

Plugging the UFM into the QuietComfort2™
Holding the UFM by the housing, gently push it
into the QuietComfort2™. The adapter should
click firmly into place. Do not force the adapter
into place as this may damage the UFM or QC2.
Using the Noise Canceling Microphone
For best performance, place the microphone
approximately 1/4”
(6 mm)
in front of the mouth.
Using the Auxiliary Audio Input Jack
Any stereo audio device can be plugged into the
auxiliary input jack, located at the base of the
microphone housing, using a standard 3.5mm Mini-
Stereo Cord. The volume of the audio input into
this jack is controlled at the device.
CAUTION:
Do not use the auxiliary audio
feature if it interferes with ATC communications.
Using the Volume (Impedance) Switch
The UFM comes with a three position volume
switch located on top of the microphone housing.
Forward
for louder audio and
aft
for softer audio.
Using the Mono/Stereo Switch
The Mono/Stereo switch is located in the cord set.
Place the switch in the one dot position for
mono
comm panels, two dots for
stereo
panels.
Using Earbuds (for TSO Compliance)
For pilots requiring TSO compliant headsets, the
auxiliary audio jack can be used as a backup audio
output. Simply plug an earbud into the auxiliary
audio jack and place the earbuds in the ear or inside
the ear cup of the QC2.
Disconnecting the UFM
To remove the UFM from the QC2, grip the adapter
by the housing and gently pull downward away
from the headphones.
