Fitting Your Headset
Fitting your headset properly is the key to the
comfortable use and the superior Active Noise
Reduction (ANR) capabilities of Zulu PFX. A solid
seal around your entire ear and a symmetrical t
across the top of your head are necessary for you to
experience peak performance from the ANR feature.
The following steps will assist you in achieving the
proper t:
1. Extend the sliders fully.
2. Place the headset on your head and compress
the sliders slowly and evenly on each side until
the head pad rests softly on the top of your head.
3. Adjust the ear cups to ensure the ears are fully
inside the ear seal and there is uniform pressure
on your head.
4. Position the microphone ⁄ inch from your mouth;
face the side of the microphone with the four
screws and Lightspeed logo away from you.
(Remove the mic windscreen to see these features.)
Getting Started
This side of the microphone
should face away from you.
Installing the CPU clip (optional)
The steel CPU clip allows you to securely position
the Zulu PFX CPU on your visor or in a map pocket.
To install, position the clip on the battery door, align
the holes in the CPU with the mounting holes in the
battery door. Use the supplied screws to attach the clip.

5
Battery Installation
TheZuluPFXANRbattery-poweredheadsetrequires
four AA batteries (included). Use alkaline batteries
for best performance.
1. Open the CPU battery door by pressing the
release button in and sliding the door down.
2. Insert four AA batteries and position them using
the correct polarity.
The power indicator LED will ash GREEN when the
power is on and the batteries are strong.
Note: When batteries begin to weaken, the power
indicator LED (for location, see page 6) ashes RED.
If the LED begins ashing RED during ight, the
headset will continue to operate for about 5 hours.
Battery Types
Use four AA alkaline or lithium batteries. Lithium
batteries may provide improved battery life in colder
temperatures. We do not recommend the use of
rechargeable batteries or the mixing of battery types
and brands.
Battery Life
A set of batteries can provide up to 20 hours of
power; however, heavy Bluetooth usage can reduce
battery life. Zulu PFX will automatically shut o
approximately ve minutes after you remove the
headset from your head. You may adjust this time
delay in the FlightLink app.

Powering the Zulu PFX Headset On
To power Zulu PFX on, follow these steps:
1. Put on the Zulu PFX ANR headset and adjust for
proper t and seal (see page 4).
2. Ensure that headset is in FAVORITES ( ) mode.
3. Press the power button once. The power indicator
LED will ash GREEN when power is supplied;
the action indicator lights will show red while the
CPU initializes and ANR system activates.
Matching Mono/Stereo Setting to an Audio Panel
The MONO/STEREO switch is located on the side of
the Zulu PFX CPU. Choose the setting that matches
the signal from your audio panel. To experience the
best performance from a stereo (dual signal) panel,
set the switch to STEREO. To experience the best
performance from a mono (single signal) panel, set
the headset to MONO.
Note: If this switch is set incorrectly, you will hear
communications in only one ear.
Note: The MONO/STEREO switch does not aect
auxiliary devices, so you can enjoy auxiliary audio in
stereo, regardless of the MONO/STEREO switch setting.

Acoustic response mapping
For maximum noise cancellation, as well as
enhanced voice clarity and music delity, use the
acoustic response mapping feature. Make sure
the HOME/FAVORITES switch is set to FAVORITES.
Press and hold the Action button until you hear the
mapping tone. The auditory landscape within the
earcupcreatedbytheuniquesizeandshapeofyour
ears will be assessed and the information used to ne
tune noise cancellation and audio responses. Each
new user should conduct the mapping process.
IMPORTANT:PressingtheActionbuttontwicequickly
enables/disables ComPriority. Flashing red Action
indicator LEDs mean that ComPriority is disabled.
Note: Although Zulu PFX stores the information
from the most recent mapping, for maximum
performance mapping should be repeated any time
a change is made that could change the landscape
within the ear cup, such as the addition of a hat or
thick-framedsunglasses.
To power Zulu PFX o, press and hold the power
button until the power indicator LED turns o.
Note: The power indicator LED ashes RED when
batteries are weak (see “Battery Installation” on
page 5).

ComPriority™
ComPriority gives priority to important
communications by lowering the volume of any
auxiliary device automatically during radio or
intercom transmission. This feature is automatically
enabled in both HOME and FAVORITES mode,
but can be disabled for all auxiliary inputs by
rapidly pressing the Action button twice (to set
Bluetooth and wired auxiliary ComPriority settings
independently, see “FlightLink Controls and Settings,”
page 17). When ComPriority is disabled, the left and
right Action indicator LEDs will ash red.
Note: When ComPriority is enabled, the other end
of a phone call is muted. They will hear you, but you
cannot hear them. To avoid this, disable ComPriority
prior to making a call.
Connecting to iPhone® or iPad® with the
Auxiliary Input Cable
If you connect an iPhone®or iPad®to the Zulu PFX CPU
using the auxiliary input cable, you can use the button
on the cable 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silverbuttonrapidlytwice.

Other Wired Auxiliary Devices
The Zulu PFX CPU’s auxiliary input jack allows you to
connect to cell phones and to most audio devices.
To connect a music player to the auxiliary input jack,
use the auxiliary input cable provided. To adjust the
volume on a device that is connected to the auxiliary
input jack, use the controls on the device itself.
Note: The Zulu PFX auxiliary input jack is on the top
of the Zulu PFX CPU (for location, see page 7).

Using Bluetooth Devices
Connecting Bluetooth Device the First Time
The Zulu PFX Bluetooth interface allows mobile
device and stereo music streaming capability
(A2DP), as well as audio alerts from aviation apps on
mobile devices. Before you use a Bluetooth device
with the Zulu PFX for the rst time, they must be
paired (establishing an electronic connection).
Pairing a Bluetooth Device with Zulu PFX
1. Press the Zulu PFX power button to turn on the
Zulu PFX headset, and then verify that the power
indicator LED is ashing GREEN.
2. Press and hold the Bluetooth power button (for
the location of Bluetooth controls, see page 7) for
about ve seconds, until the Bluetooth indicator LED
continuously ashes RED and BLUE. This ashing
indicates that Zulu PFX is in Bluetooth pairing mode.
3. Follow the menu prompts on your Bluetooth
capable device to direct it to look for
Bluetooth devices.
4. Select Zulu PFX #### (numbers will be the last
four digits of the Zulu PFX headset serial number)
from your phone’s list of found devices.
5. Enter “0000”if you are prompted to enter a
password or PIN.
6. Once paired, the Bluetooth LED will ash BLUE.
Note: If the headset is not connected to a
compatible device within three minutes, Bluetooth
will exit pairing mode and turn o.

14
Automatic Bluetooth Connection
When the Bluetooth feature is on, the Zulu PFX will
automatically connect to the most recently paired
device. If no device is connected, Zulu PFX will remain
in pairing mode for three minutes, after which it will
exit pairing mode and Bluetooth will turn o.
If Zulu PFX does not automatically reconnect, follow
the menu prompts on your Bluetooth capable
device to direct it to look for Bluetooth devices.
Bluetooth Functions
Depending on your phone’s Bluetooth prole, you
may be able to use Zulu PFX’s Bluetooth buttons to
perform several functions:
• Voicedial:PresstheBluetoothpowerbutton
until you hear a single beep; your phone must
