Introduction
Getting Started
Fitting your headset
Fitting your headset properly is the key to
comfortable use and superior Active Noise
Reduction (ANR) capabilities. To gain peak
performance from the ANR feature it’s necessary
to have a solid seal around your entire ear
combined with a symmetrical t on your head.
The following tips will assist in achieving the
proper t.
A. Fit your ears entirely within the ear cups
providing a solid seal.
B. Rest the headband lightly on top of your
head with the right and left sliders extended
to equal lengths.
C. Position the microphone inch from your
mouth, with the gain adjustment cap facing
away from you (visible when you remove the
mic mu).
Note: The microphone will not transmit unless
plugged into an intercom.

This side of the microphone
should face away from you.
Battery installation
The Sierra headset requires two AA batteries
(included). Use alkaline or lithium batteries for
best performance.
A. Open the controller battery/DIP switch door
by either pressing down on the circle icon or
by pulling open the door along the notched
edges. Insert two AA batteries with the
correct polarity positioning.
B. The LED ashes GREEN when charged
batteries are in use and the power is on.

C. When batteries begin to run
low the power LED ashes
red. If the LED ashes red
during ight the headset will
continue to operate. Install
new batteries as soon as
possible at any indication of
low batteries.
Battery types
Use two “AA” alkaline or lithium batteries. Lithium
batteries may provide improved battery life in
colder temperatures. We do not recommend
using rechargeable batteries or mixing battery
types and brands.
Battery life
A set of batteries can provide up to 40 hours
of power. However, heavy usage of Bluetooth®
wireless technology can signicantly reduce
battery life. Under quiet conditions Sierra will
auto shut o approximately ve minutes after the
headset is removed from your head.

is engaged when you turn on the headset.

quiet conditions.
The power LED ashes red when batteries are

Matching stereo/mono setting to an audio panel
The stereo/mono DIP switch setting should
match the signal from your audio panel. For a
stereo panel, best performance is gained by
setting the headset for stereo. The same is also
relevant to a mono panel. Incorrect settings result
in communications being heard in only one ear.
The Stereo/Mono DIP switch does not aect
auxiliary devices, so you can enjoy auxiliary audio
in stereo regardless of how the Stereo/Mono DIP
switch is set.
Setting the DIP switch
The DIP switch is factory set to match most
aircraft audio panels. To change a DIP switch
setting open the controller battery compartment
door. Use a small pointed object like a wood
