Fit
The Zulu H-Mod ANR kit is optimized to deliver
clarity and quieting with comfort. Contrary to most
in-helmet passive systems, this ANR kit does not
need signicant pressure to ensure quieting.
For adjustments in tting, you should refer to the
helmet dealer who provided the certied installation
of your Zulu H-Mod ANR kit. The tting instructions
for each helmet will vary considerably.

Battery Installation
The standard Zulu H-Mod requires 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 for 5–10
more hours. 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® wireless
technology usage can signicantly reduce battery
life. Under quiet conditions Zulu H-Mod will auto
shut o approximately ve minutes after the helmet
is removed from your head.

Using Your Zulu H-Mod
Turning ON and OFF
ON: Press the power button once to turn on the
system. The GREEN power LED ashes when power
is supplied. Active Noise Reduction (ANR) is engaged
when you turn on the system.
OFF: Press and hold the power button until the
GREEN power LED turns o.
Zulu H-Mod will auto shut o approximately ve
minutes after removing the helmet and under quiet
conditions.
The power LED ashes RED when batteries are low;
see Battery Installation on page 4.
Matching Stereo/Mono Setting to an Audio Panel
The Stereo/Mono DIP switch setting should match
the signal from your audio panel. Zulu H-Mod is
shipped in Mono (the “on” position) so you only
need to change the setting if you use a stereo panel.
STEREO should be used for a stereo panel and
MONO for a mono panel. Incorrect settings result
in communications being heard in only one ear or
weakly in both. This 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™
Front Row Center is a built-in feature that gives you
a theater-like experience, enhancing stereo sound
reproduction so that audio seems to come from all
around you, not just from your right and left.
8

ComPriority™
ComPriority is turned on or o by the bottom-most
controller button. With ComPriority enabled when
radio communications are detected, the volume
of auxiliary devices will be signicantly reduced.
ComPriority is enabled by default when you power
on your Zulu H-Mod. Plug into your intercom and
talk into the microphone while playing music
using a wired device. If ComPriority is enabled, your
auxiliary music volume will decrease when you start
to talk. During cell phone calls, the other party will
be muted, so you should disable ComPriority before
making calls.
Using Your Zulu H-Mod

Wired Auxiliary Devices
Zulu H-Mod’s wired auxiliary input allows you to
connect to cell phones and to most audio devices.
To connect a music player to the auxiliary input jack,
use the cord provided. To adjust the volume on a
device connected to the 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
answer the call.
• Disconnecting a call: Press the button to
disconnect the call; music automatically resumes.

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.

phone calls.

Using Devices Enabled by Bluetooth Technology
12
Connecting to Mobile Devices for the First Time
The Bluetooth interface allows cell phone and stereo
music streaming capability (A2DP). Before using a
mobile phone for the rst time with Zulu H-Mod,
it must be “paired”or electronically connected via
Bluetooth wireless technology.
To pair a mobile phone or device:
1. Turn on the system and verify the GREEN LED
is ashing. Make sure the Bluetooth mode is
turned OFF. (See “Bluetooth Mode—ON and
OFF”, page 13).
2. Press and hold the Bluetooth button for about
ve to ten seconds or until the Bluetooth LED
continually ashes RED and BLUE. This indicates
the 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. In pairing mode, follow the menu prompts on
your Bluetooth wireless technology enabled
device directing it to look for other Bluetooth
wireless technology enabled devices.
4. Select Lightspeed-V### (numbers may vary) on your
mobile device from the list of found devices.
5. If asked to enter a password or PIN, enter 0000.
Your mobile device should now be paired and ready
for continued use.
When you turn on Bluetooth mode again, it will
connect to the most recently paired device. Most
mobile devices connect automatically. If that doesn’t
happen it may be necessary to use the settings

audio, you will need to run it on a second device to
prevent interruption of FlightLink recording.

Quick Disconnect
Quick Disconnect cable
Experience fast, safe egress with Lightspeed’s exclusive
quick-disconnect cable that has a 9-pound pull force
(4 kg) and makes emergency egress even safer.
To know if this feature is connected properly, there
are two ways you can verify its proper alignment:
visually and mechanically. Visually you can align
two indicators (red dots) on each connecting end
of the Quick Disconnect feature. When the red dots
are aligned, the connection is correct. The second
is a tactile way, or non-visual. Spin the two ends
once aligned until you hear or feel a click. The Quick
Disconnect must be aligned or won’t snap in.
15
In non-emergency situations, the power should be
turned o instead of using the Quick Disconnect
feature to power o.

FAQs
Why do I hear radio communications in only
one ear, or weakly in both?
The Zulu H-Mod Stereo/Mono DIP switch is likely
set to Stereo while your audio panel is transmitting
a mono signal. To x this, change the Stereo/Mono
DIP switch to Mono (the “on”position). 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 H-Mod with my phone via
Bluetooth wireless technology, why does my
phone indicate it cannot connect?
The system may not be in pairing mode. To enter
pairing mode, you must start with Bluetooth mode
turned fully OFF; (see “Connecting to Mobile Devices
for the First Time,” on page 12).
Why doesn’t my phone accept the 0000
passcode when I try to connect via Bluetooth
wireless technology?
Your system may not be in pairing mode. Some
phones prompt for a pass code without checking
for pairing mode. When the phone cannot pair, it
rejects the passcode. To enter pairing mode, you must
start with Bluetooth mode turned fully OFF (see
“Connecting to Mobile Devices for the First Time,”
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 controller
when making calls.

FAQs
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.
See “Fit,” on page 4.
