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 fit on your head.
The following tips will assist you in achieving the
proper fit.
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.
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 flashes GREEN when charged batteries
are in use and the power is on.
C. When batteries begin to run low the power LED
flashes RED. If the LED flashes RED during flight
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
SFDIBSHFBCMFCBUUFSJFTPSNJYJOHCBUUFSZUZQFTBOE
brands.
Battery Life
A set of batteries can provide up to 40 hours of
power. However, heavy Bluetooth usage can
significantly reduce battery life. Under quiet
conditions Zulu.2 will auto shut offapproximately
five 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 affect auxiliary devices, so you can enjoy
auxiliary audio in stereo regardless of how the Stereo/
Mono DIP switch is set.

most controller button. With Auto MusicMute on and
when radio communications are detected, the volume
of auxiliary devices will be significantly 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;
seeWired Auxiliary Devices. If enabled, your auxiliary
music will decrease when you start to talk.
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.
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 like a wood toothpick to slide the DIP
switch to ON or OFF depending on your preference.

Zulu.2’s Bluetooth interface allows cell phone and
stereo music streaming capability (A2DP).
Connecting Bluetooth Cell Phones for the FirstTime
Before using a Bluetooth cell phone for the first
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 flashing. Make sure Zulu.2’s Bluetooth
mode is turned OFF. BLUE or RED flashes 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 five 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.

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

Depending on the Bluetooth profile of the phone,
you can use Zulu.2’s Bluetooth buttons to perform
several functions. Some typical functions are:

Bluetooth Mode—ON and OFF
ON: With Zulu.2 turned ON, press and hold the Bluetooth
button; see page 6, until you hear a high tone and the
Bluetooth indicator LED flashes three BLUE pulses. For
first time pairing see instructions on page 12.
OFF: Press and hold Zulu.2’s Bluetooth button for
about three seconds until a high tone is emitted and
the Bluetooth indicator LED flashes three RED pulses.
Note: The Bluetooth feature must be turned ON for
Bluetooth connected devices to correctly function.

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 fix this, change Zulu.2’s Stereo/
Mono DIP switch to Mono. This setting does not
affect 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.
'"2T
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.
