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 is necessary to have a solid
seal around your entire ear combined with a
symmetrical t on your head.
The following tips will assist you 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.
Getting Started
4
C. Position the microphone  inch from your mouth,
with the gain adjustment cap facing away from
you (visible when you remove the mic mu).
This side of the microphone
should face away from you.

Battery Installation
The standard Zulu.2, Zulu.2:CD and Zulu.2:C battery–
powered headsets require two AA batteries (included).
Use alkaline 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 Bluetooth usage can
signicantly reduce battery life. Under quiet
conditions Zulu.2 will auto shut o approximately
ve minutes after the headset is removed from
your head.

Using Your Zulu.2 Headset
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.
Front Row Center™

around you, not just from your right and left.
ComPriority™
ComPriorityisturnedonorobythebottom-most

radio communications are detected, the volume
of auxiliary devices will be signicantly reduced. To
enable ComPriority, turn on the feature, plug into
your intercom and talk into the headset microphone
while playing music over a wired device. If enabled,
your auxiliary music will decrease when you start to
talk. During cell phone calls, the other party will be
muted, so disable ComPriority before making calls.
Wired Auxiliary Devices
Zulu.2’s wired auxiliary input allows you to connect
to cell phones and to most audio devices. To
connect a music player to Zulu.2’s auxiliary input
jack, use the cord provided.

To adjust the volume on a device connected to
Zulu.2’s auxiliary input jack, use the controls on the
device itself.
Connecting to iPhone or iPad with the
Auxiliary Input Cord
If you connect to an iPhone or iPad using the wired
auxiliary input cord, you can use the silver button
on the cord to perform the following functions:
• Play/Pause: Press the button once to Pause
music; press the button again to Play music.
• Track Forward: Press the button twice rapidly to
track forward.
• Answering calls: Music automatically mutes and
pauses for an incoming call. Press the button to

Setting DIP Switches
DIP switches are
factory set to match
most aircraft audio
panels. To change a
DIP switch setting
open the controller
battery/DIP switch
door. Use a small
pointed object such
as a wood toothpick
to slide the DIP switch to ON or OFF depending
on your preference.

For FlightLink to work properly, it must be in the ON
position. This will also aect cell phone usage —
when in the ON position, the recipient of a cell
phone call will hear all sounds on the intercom.
To avoid this, unplug your headset from the panel
during phone calls.

Connecting Bluetooth Cell Phones for the First Time
Zulu.2’s Bluetooth interface allows cell phone and
stereo music streaming capability (A2DP). Before
using a Bluetooth cell phone for the rst time with
Zulu.2 it must be“paired”or electronically connected.
To pair a Bluetooth cell phone with Zulu.2:
1. Turn on the headset and verify the GREEN LED
is ashing. Make sure Zulu.2’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 13).
2. Press and hold the Zulu.2 Bluetooth button for
about ve to ten seconds or until the Bluetooth
LED continually ashes RED and BLUE. This
indicates the Zulu.2 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 Zulu.2 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 Zulu.2.
When you turn on the Zulu.2 Bluetooth mode it will
connect to the most recently paired device.

Most Bluetooth cell phones connect to Zulu.2
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).
Bluetooth Features
Depending on the Bluetooth prole of the phone,
you can use Zulu.2’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

Why do I hear radio communications in only
one ear?
Zulu.2’s Stereo/Mono DIP switch is probably set
to Stereo while your audio panel is transmitting
a mono signal. To x this, change Zulu.2’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 Zulu.2 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,” on page 12).
Why doesn’t my Bluetooth phone accept Zulu.2’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,”on page 12).
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 Zulu.2
controller and headset when making calls.
FAQs
16

When ying, what causes a warbling noise in
the ear cup?
If your ear is not entirely inside the cup, with a
tight seal, air can seep in and cause the ANR to
compensate for uneven internal cup pressure.
Where is my product serial number?
The Zulu.2 serial number (a
small,white,bar-codesticker
with numbers) can be found
on the headset underneath the
head pad. The head pad, located
on the inner radius of the
headband, must be removed to
reveal the serial number. Simply
pinch the cushioned part of the head pad, pull
down and it will snap out.
