Setting up Zulu
What’s in the box
Your Zulu headset package includes:
Fitting your headset
A good headset fit is a key part of both comfort and ANR performance. Zulu’s Active
Noise Reduction feature requires a good seal around your ears and a symmetrical
fit over your head. When properly fitted, the ear cups should completely cover your ears
and the headband should rest lightly on top of your head.
To fit the headset to your head:
1. Fully extend both ear cup sliders.
2. Put the headset on with the microphone and cable to your left.
3. Pressing the top of the headband down onto your head, slide up each ear cup until it
covers your entire ear without pinching any part of your ear under the seal. Make sure
the two ear cup sliders are extended an equal amount.
4. Position the microphone 1/8 inch from your mouth.
The Zulu headset adjusts to fit most adults. If you have a small head or are using the
headset for a child, contact Lightspeed for different headpads

Changing batteries and monitoring battery life
Zulu requires two AA batteries (included). Use
alkaline batteries for best performance.
When Zulu is turned on and battery power is strong,
the power indicator LED flashes green. Under
normal conditions, a set of batteries provides up
to 50 hours use; however, heavy Bluetooth use can
significantly reduce battery life.
When batteries run low, the power LED flashes
red. If the power LED flashes red when you first
turn on the headset, Lightspeed recommends
that you install fresh batteries before take-off.
If batteries run low during flight, it’s best to keep
Zulu powered on continuously until you can
change the batteries safely.
To install batteries, open the battery door
on the back of the Zulu controller, either by
pressing down on the circle icon to pop open
the door or by prying open the door along its
grooved edges. Alternatively, you can grasp
the finger grips on the sides of the battery
door and pull up with a slight diagonal twist.
Zulu’s power shuts off automatically 2 minutes
after you remove the headset from your head.

Turning on and off Zulu
When you turn on Zulu, you turn on Active Noise Reduction (ANR) as well. To turn on
Zulu, press the power button once. To turn off Zulu, press and hold the power button.
Zulu’s power shuts off automatically 2 minutes after you remove the headset from
your head.
When power is supplied to Zulu and the batteries are strong, the power indicator
LED flashes green. When the batteries are running low, the power LED flashes red.
See “Changing batteries and monitoring battery life” on page 5 for information
on battery use.
Using Front Row Center to enhance stereo
The FRC button toggles on and off Front Row Center (FRC®). Front Row Center gives
you a theater-like listening experience, enhancing stereo sound reproduction so that
audio seems to come from all around you, not just from your right and left.
Using Auto MusicMute to quiet auxiliary devices
The bottom-most button on the Zulu Controller toggles on and off Auto MusicMute.
When radio communications come in from the panel, Auto MusicMute decreases
the volume of auxiliary devices by 80%. To test whether Auto MusicMute is enabled,
simply talk into your headset microphone while playing music over a wired or Bluetooth
auxiliary device (see “Using auxiliary devices” on page 9). If Auto MusicMute is on, it will
turn down your auxiliary music when you start to talk.
Note: Auto MusicMute does not affect cell phone calls.

Matching Zulu’s Stereo/Mono setting to your audio
panel signal
For best results, Zulu’s Stereo/Mono DIP switch setting should match the signal from
your audio panel. If you are using a stereo audio panel, Zulu should be set to Stereo for
best sound quality. If you are using a mono audio panel, Zulu should be set to Mono;
otherwise, you will hear radio communications in only one ear. The Stereo/Mono DIP
switch does not affect auxiliary devices, so you can enjoy auxiliary audio in both stereo
and FRC regardless of how the DIP switch is set. For information on setting DIP switches,
see “Setting DIP switches” on page 12.
Getting the best possible performance from Zulu
Follow these tips to get the best possible performance from your Zulu headset:
■Make sure you have an excellent fit—see “Fitting your headset” on page 4.
■For a theater-like listening experience, press FRC to turn on Front Row Center.
■For the best sound quality when listening to music or other audio entertainment, use
an audio device that is plugged into the auxiliary input jack.
■Make sure Zulu’s Stereo/Mono DIP switch setting matches the signal from your audio
panel; see “Matching Zulu’s Stereo/Mono setting to your audio panel signal,” above.
■If you need a little help hearing speech clearly during radio communications or phone
calls, try using Treble boost (see “Setting DIP switches” on page 12). If you do not need
the extra boost, keep this feature turned off for a more realistic sound.
■To prevent static noise during phone calls, keep cell phones at least 12 inches from
the Zulu Controller and headset when making calls.

Using auxiliary devices
You can use auxiliary devices such as music players and cell phones by connecting to
Zulu’s auxiliary input jack or by connecting wirelessly using Bluetooth. You get the best
sound quality when you connect devices to Zulu’s auxiliary input jack.
To enhance stereo sound when listening to auxiliary audio devices, turn on Front Row
Center. You can also use Zulu’s Treble boost and Bass boost DIP switches to adjust the
sound. Zulu’s Stereo/Mono DIP switch setting does not affect auxiliary devices, so you
can listen to auxiliary audio in both stereo and FRC even when Zulu is set to mono.
When Auto MusicMute is on, Zulu automatically turns down auxiliary devices during
radio communications; see “Using Auto MusicMute to quiet auxiliary devices” on
page 7.
Connecting a wired device to the auxiliary input jack
To connect a music player or cell phone to Zulu’s auxiliary input jack, use the
appropriate supplied cable. Some cell phones use proprietary connectors and
require an adapter or special cable—call Lightspeed if you need help with your setup.
To adjust the volume on a device connected to Zulu’s auxiliary input jack, use the
controls on the device itself.
Using wireless devices with Zulu
Before you can connect a wireless Bluetooth device for the first time, you must pair it
with Zulu. This procedure is described in “Connecting a Bluetooth device for the first
time” on page 10. Once you pair your Bluetooth device with Zulu, you can connect to it
easily when Zulu’s Bluetooth mode is turned on. For details on using Bluetooth devices
with Zulu, see “Using a Bluetooth device” on page 10.

Connecting a Bluetooth device for the first time
Before you can connect a Bluetooth device to Zulu for the first time, you must pair it
with Zulu. Use the steps below.
To pair a Bluetooth device with Zulu:
1. Make sure Zulu’s Bluetooth mode is turned fully off. You should not see blue or

5 seconds, until the Bluetooth LED flashes alternating red and blue. This puts
Zulu in pairing mode.
