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 1/8 inch from your
mouth. Speak into the microphone side labeled
“talk” which is marked at the microphone base.
Note: The Microphone will not transmit unless
plugged into an intercom.
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

Getting Started

Battery Types
Usetwo“AA”alkalineorlithiumbatteries.Lithium
batteries may provide improved battery life in
colder temperatures. We do not recommend
using re-chargeable batteries or mixing battery
types and brands.
Battery Life
A set of batteries can provide up to 40 hours of
power. However, heavy Bluetooth usage can
signicantlyreducebatterylife.Underquiet
conditions Sierra will auto shut o approximately
two minutes after the headset is removed from
your head.
The Controller

Turning ON and OFF
ON: Press the power button once to turn on the
headset.TheGREENpowerLEDasheswhen

conditions.
ThepowerLEDashesREDwhenbatteriesare
low; see Battery Installation, on page 5.
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 aect 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
toothpick to slide the DIP switch to ON or OFF
depending on your preference.
Auto MusicMute
Auto MusicMute is turned on or o by the
bottom-most controller button. With Auto
MusicMute on and when radio communications
are detected, the volume of auxiliary devices will
be signicantly reduced.
To enable Auto MusicMute, turn on the feature,
plug into your intercom and talk into the headset
microphone while playing music over a wired
device; see Wired Auxiliary Devices, on page 9. If
enabled your auxiliary music will decrease when
you start to talk.
Note: Auto MusicMute does not aect cell phone calls.
8 9
Wired Auxiliary Devices
To connect a music player to Sierra’s auxiliary
input jack, use the cord provided.
To adjust the volume on a device connected to
Sierra’s auxiliary input jack, use the controls on
the device itself.
Cell phone capability works only when
connected via Bluetooth, not through the
auxiliary input jack.
Note: Sierra will not stream music wirelessly.

Bluetooth and Cell Phones
Connecting Bluetooth Cell Phones for the First
Time
Before using a Bluetooth cell phone for the
rst time with Sierra it must be “paired” or
electronically connected.
To pair a Bluetooth cell phone with Sierra:
1. TurnontheheadsetandverifytheGREEN
LED is ashing. Make sure Sierra’s Bluetooth
modeisturnedOFF.BLUEorREDashesfrom
the Bluetooth LED should not be present (see
“Bluetooth Mode—ON and OFF”, page 11).
2. Press and hold the Sierra Bluetooth button
for about ve to ten seconds or until the
BluetoothLEDcontinuallyashesREDand
BLUE.ThisindicatestheSierrapairingmode
setting and lasts about two minutes. If this
step takes longer and the Bluetooth LED is no
longeralternatingREDandBLUE,startover
from step one.
3. With Sierra in pairing mode, follow the menu
prompts on your Bluetooth phone directing
it to look for Bluetooth devices.
4. Select Lightspeed-V### (numbers may vary)
on your Bluetooth phone from the list of
found devices
5. If asked to enter a password or PIN, enter 0000
Your cell phone should now be paired and ready
for continued use with Sierra.
Bluetooth Mode—ON and OFF
ON: With Sierra turned ON, press and hold the
Bluetooth button; see page 7, until you hear
a high tone and the Bluetooth indicator LED
ashesthreeBLUEpulses.Forrsttimepairing
see instructions on this page.
OFF: Press and hold Sierra’s Bluetooth button for
about three seconds until a high tone is emitted
and the Bluetooth indicator LED ashes three
REDpulses.
Note: The Bluetooth feature must be turned ON
for Bluetooth connected devices to correctly
function.
When you turn on the Sierra Bluetooth mode it
will connect to the most recently paired device.
Most Bluetooth cell phones connect to Sierra
automatically. If that doesn’t happen it may be
necessary to use the cell phone menu of found
devices to signify Lightspeed-V### (numbers
may vary).
Note: The microphone will not transmit unless
plugged into an intercom.
Note: Sierra will not stream music wirelessly.

Bluetooth Features
Depending on the Bluetooth prole of the phone,
you can use Sierra’s Bluetooth buttons to perform
several functions. Some typical functions are:
• PresstheBluetoothbuttononceforvoice
dialing (if supported by your phone).
• PresstheBluetoothbuttononcetoanswer
the phone when it rings.
• PresstheBluetoothbuttononceto
disconnect from a call.
• PressandholdtheBluetoothbuttonfortwo
seconds to redial the last number called.
• UsetheBluetoothvolumebuttons(Sierra’s+
and – buttons) to adjust the volume.
Note: Cell Phone capability works only when
connected via Bluetooth.
Why do I hear radio communications in only
one ear?
Sierra’s Stereo/Mono DIP switch is probably set
to Stereo while your audio panel is transmitting
a mono signal. To x this, change Sierra’s Stereo/
Mono DIP switch to Mono. This setting does not
aect music or audio from auxiliary devices; you
can hear stereo sound on auxiliary devices even
when the Stereo/Mono DIP switch is set to Mono.
When pairing Sierra with my Bluetooth
phone, why does my phone indicate it cannot
connect?
The headset may not be in pairing mode. To enter
pairing mode, you must start with Bluetooth mode
turned fully OFF; (see “Connecting Bluetooth Cell
Phones for the First Time,” on page 10).
Why doesn’t my Bluetooth phone accept
Sierra’s 0000 passcode?
Your headset may not be in pairing mode. Some
phones prompt for a pass code without checking
for pairing mode. When the phone cannot pair
with the headset, it rejects the passcode. To enter
pairing mode, you must start with Bluetooth mode
turned fully OFF (see “Connecting Bluetooth Cell
Phones for the First Time,” on page 10).
How can I reduce static noise during cell
phone calls?
ToreduceRFinterferenceduringphonecalls,
keep cell phones at least 12 inches from the
Sierra controller and headset when making calls.
