Zulu User Guide 5

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 cord 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
The Zulu:CD and Zulu:C battery –powered headsets require two AA
batteries (included). Use alkaline batteries for best performance.
To install batteries, open the battery/DIP switch 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 notched edges.
When Zulu is turned on and battery power is strong, the power
indicator LED flashes green. Under normal conditions, a set of
batteries provide 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.
Zulu’s power shuts off automatically two minutes after
you remove the headset from your head.

Turning Zulu on and o
When you turn on Zulu, you turn on Active Noise Reduction (ANR) as well. To turn on Zulu,
press the power button once. When power is supplied to Zulu, the power indicator LED flashes
green. (For battery-powered headsets, the power LED flashes red when batteries are low; see
“Changing and monitoring battery life,”on page 7).
To turn off Zulu, press and hold the power button until the power LED turns off. During
shutdown, the power LED glows briefly to show the power status, either green for full
power or red for low batteries.
Zulu’s power shuts off automatically two minutes after you remove the headset from your head.
Using Front Row Center to enhance stereo
The FRC button toggles on and off Front Row Center. Front Row Center 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.
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 11). 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.
Zulu User Guide 9

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 the 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 Front Row Center regardless of how the Stereo/Mono DIP switch is set. For
information on setting DIP switches, see “Setting DIP switches,” on page 14.
