Getting Started
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 our
ANR feature, it is necessary to have a solid seal around your entire ear,
together with a symmetrical fit on your head.
4. Position the microphone 1/8 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.)
The following tips will assist you in achieving the proper fit.
1. Extend the sliders fully.
This side of the microphone should face away from you. The small `cap’ (larger disk in the middle) on the back is to access a Microphone gain adjustment.
2. Place the headset on your head and compress If you need a tighter fit to ensure a good seal
the sliders slowly and evenly on each side until around your ears, please call Customer Service at
the head pad rests softly on the top of your head. 800-332-2421 or email support@lightspeedaviation.com
3. Adjust the ear cups to ensure the ears are fully inside the ear seal and
there is uniform pressure on your head.

to receive assistance. There are a number of possible solutions that will work and the team will guide you through the process to make sure you get the very best performance.
Getting Started
The Head pad and Ear seals
Our tapered ear seals are designed to hug the curve of your jaw for a natural
fit, increasing comfort and clarity while also providing a better seal around
glasses frames.
If you feel that your ears are not centered within the ear cups, even after
collapsing the sliders completely, a taller head pad might be the solution.
This will move the ear cups further up the side of your head to allow you to
center your ears within the cups.
To order a complimentary tall head pad (part number A484), please call Customer Service at 800-332-2421 or email support@lightspeedaviation.com and mention promo code FTHP. You will be asked to provide your headset serial number. (See page 27 to locate your serial number.)

Getting Started
Battery Installation The GA and Helicopter versions of Delta Zulu battery-
powered headsets require either two AA batteries or the rechargeable lithium
ion battery cartridge (both included) for best performance. A. Pinch the
narrow buttons on each side of the
control box to release the battery cartridge. One of the battery cartridges
that came with your headset holds two AA batteries. Slide open the small door
to insert the batteries with the correct polarity positioning.
8
B. The LED flashes GREEN when the batteries are charged 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 for 45 more
hours. Install new batteries as soon as you can after the LED flashes RED.
Battery Types Pilots can choose to use either two AA alkaline or rechargeable
lithium ion batteries. Lithium ion batteries may provide improved battery life
in colder temperatures.
The easy to replace battery pack gives you the option of using AA batteries or
the included rechargeable lithium ion battery pack.
Additional batteries and cartridges are available at LightspeedAviation.com
Battery Life
Lightspeed’s Auto Shutoff feature saves battery life by automatically shutting
down the headset power when not in use. Delta Zulu will auto shut off
approximately five minutes after the headset has been removed from your head.
Lithium-Ion batteries can provide over 30 hours of power and will take
approximately 8 hours to charge when fully depleted. However, theses batteries
can be charged while the headset is in use via USB cable power. Supplemental
AA batteries can extend your power up to 15-20 hours. Heavy Bluetooth wireless
usage can reduce battery life.

Using Your Delta Zulu Headset
Matching Stereo/Mono Setting to an Audio Panel
The Stereo/Mono DIP switch setting should match the signal from your audio
panel. Delta Zulu is shipped with the Mono setting on. You will need to change
the setting to Stereo if you use a stereo panel found with panel power
installations. STEREO should be used for a stereo panel and MONO for a mono
panel.
Incorrect settings result in communication being heard in only one ear or
weakly in both ears.
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.
ComPriorityTM
ComPriority is enabled by default when you power on your headset.
ComPriority is turned on or off by the bottom controller button. The pilot
will be notified via an audio cue that the function is enabled or disabled.
When ComPriority is enabled and radio communications are detected, ComPriority
automatically lowers the volume of any auxiliary device during radio or
intercom transmissions. For instance, when listening to music using a wired or
Bluetooth device, your auxiliary music volume will decrease when you begin to
speak. The soft mute feature gently eases music back in for a smooth listening
transition.
ComPriority should be disabled before making cell phone calls because the
other party will be muted.
To enable/disable ComPriority, press the bottom controller button, which is a
toggle button, to either enable/disable ComPriority.

helicopter audio panels. If you plan to use this feature and keep the switches
set to ON, test the headset in the cockpit before takeoff.
Switch 5 on the product is an enable/disable function for charging over USB.
This is useful for disabling charging from an iPad (iPad Pro) with USB-C.
However, if it is disabled then the headset will not power or charge over
either USB-C or USB-A.
15
Using Your Delta Zulu Headset
Personalizing Your Headset (4 icon chip set)
Because your preferences and HearingEQityTM profile are stored in the headset,
you may want to identify your headset when it is being used in the same plane
as other Delta Zulus. You can personalize your own model by replacing the
standard gold chip with another chip from the included icon set. To replace
the chip, simply remove the battery module, and locate the color chip at the
bottom of the controls surface. Using you fingernail, or a small plastic
screwdriver, pry up on the color chip. Select the new color chip and center
the color chip over the keyed hole in the control box. Once centered, press
down on the color chip until it is flush with the surface of the control box.
16
UAC Cables for Charging, Audio, and Data
UAC Plug
The Delta Zulu is the first headset to use a Universal Accessory Connector
(UAC) which provides a single access point for charging, data communications,
and auxiliary audio.
UAC Cables for Charging, Audio, and Data
Delta Zulu comes with one (1) 2-way direction UAC cable (USB A to UAC) and
is compatible with three more. A UAC connector is a smaller connector that has
a standard port on one end of each cable, with the option of a USB-C, USB-A,
Lightning, or 3.5mm jack at the other. The platform is also capable of audio
and data transfer.
Lithium Ion Batteries charge with: · USB-A to UAC · USB-C to UAC

Bluetooth® Wireless Technology
Bluetooth Features Depending on the Bluetooth profile of the connected device,
you can use the Delta Zulu Bluetooth buttons to perform several functions.
Some typical functions are:
· Press the Bluetooth button once for voice dialing (if supported by your
phone).
· Press the Bluetooth button once to answer a call.
· Press the Bluetooth button once to disconnect from a call.
· Press and hold the Bluetooth button for two seconds to redial the last
number called.
· Use the Bluetooth volume buttons (+ and buttons) to adjust the volume. You
may also adjust the volume on your connected device.
18
Bluetooth Mode–ON and OFF
The Bluetooth feature automatically turns on when you power on the headset. On
the first power up the headset will enter into pairing mode (as seen by an
alternating red & blue LED). The headset will remain in pairing mode for
approximately 1 minute to allow you time to open your settings on your phone
or tablet and pair to the headset. On subsequent power ups, the headset will
attempt to reconnect to the device that it was last paired to. If that device
is not found, the headset will enter pairing mode again for 1 minute. If at
the end of 1 minute no device is paired, the Bluetooth function turns off. To
start the pairing process again, press the Multi-function Button (MFB) 3 times
to enter forced pair mode.
Note: The Bluetooth feature must be turned on for devices connected via
Bluetooth to function correctly.
Bluetooth® Wireless Technology
Pairing a Mobile Phone or Device
1. Turn on the headset and verify the GREEN power LED is flashing.
2. After 10 seconds, the Bluetooth LED will continually flash RED and BLUE.
This indicates pairing mode and lasts about one minute. If this step takes
longer and the Bluetooth LED is no longer alternating RED and BLUE, turn off
the headset and begin again with step 1, or press the Multi-function Button 3
times.
3. When Delta Zulu is 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 Delta Zulu_#### (the numbers indicate the last 4 digits of the
headset serial number) on your mobile device from the list of found devices.
Your mobile device should now be paired and ready for continued use with Delta
Zulu.
When you turn on Bluetooth mode again, it will connect to the most recently
paired device. Most mobile devices connect to Delta Zulu automatically. If
that doesn’t happen, it may be necessary to use the settings menu of your
device to choose and reconnect, or repair Delta Zulu_#### (numbers may vary).
Connecting Mobile Devices for the First Time
Bluetooth wireless technology with the Advanced Audio Distribution Profile
(A2DP) enables stereo music streaming and the Hands-Free Profile (HFP) enables
phone calls. Prior to using a cell phone or mobile device for the first time
with Delta Zulu, it must be paired or electronically connected via Bluetooth
wireless technology.
19
Features of KanariTM Technology
Carbon Monoxide (CO) Detection The Delta Zulu headset has a built-in CO sensor
to detect hazardous levels of CO.
CO can accumulate inside an aircraft’s cockpit in several ways including
through leaky door seals, landing gear seals and the rear bulkhead.
The built-in sensor monitors the CO in the environment and will send an alert
through the headset at the cautionary and critical levels.
Note: the KanariTM smart alerts work independently of the Lightspeed App.
Connection to the app is not necessary – they work automatically.
CO Sensor
The built-in CO sensor is always on and monitoring. You have the ability to
set your own timing for cautionary alerts (to be set from 5 to 15 minutes);
For critical alerts, they come every 2 minutes, unchangeable.
· Adjustable Low CO threshold = 10-50 ppm (cautionary warning)
· Adjustable High CO threshold = 51-100 ppm (critical warning)
20
Features of KanariTM Technology
Warnings and Errors The headset will continually monitor the status of all
environmental sensors. If there is a malfunction, you will be alerted to the
error. The warning alerts method can be setup in the Lightspeed app. The
carbon monoxide alerts can be set up to provide voice only or a tone prior to
the voice during alerts from the headset. Additionally, you can set the carbon
monoxide alerts to alert you on the left, right, or both audio channels. The
Multi-Function button is the way to mute the alerts from the headset.
21
HearingEQityTM
HearingEQity HearingEQity uses your personal results from a custom built-in
12-frequency hearing test on your mobile device to analyze your hearing. With
HearingEQity, every ATC call and conversation is optimized specifically for
your hearing acuity.
Our new HearingEQity technology is an audio equalization system that
compensates for your hearing loss.
HearingEQity is incorporated into the Lightspeed app which adjusts and sets
the hearing levels in each of the ears of your headset. Using your mobile
device, HearingEQity tests and personalizes your hearing experience using an
automated 12-frequency analysis that transforms any hearing loss into
remarkably clearer ATC and intercom communications, music and auxiliary
devices. Using this test, a user profile is created and stored in the headset.
Once the profile is stored in the headset, the app does not need to be
connected for HearingEQity to be active.
22
Lightspeed App

FAQs
Why do I hear radio communications in only one ear, or weakly in both?
The Delta Zulu Stereo/Mono DIP switch is likely set to Stereo while your audio
panel is transmitting a mono signal. To fix this, change the Delta Zulu
Stereo/Mono DIP switch to Mono (the “on” position). 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.
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. If you are having difficulty connecting,
disconnect the battery cartridge and start the pairing over. It’s a good
practice to turn off Bluetooth before turning off your headset which may help
retain the pairing.
Why is the Smart Button action “Force Bluetooth How can I reduce static noise during cell phone calls? Pairing” not working?
To reduce RF interference during phone calls, keep cell phones at least 12
inches from the Delta Zulu controller and headset when making calls.
When pairing Delta Zulu with my phone via Bluetooth wireless technology, why

A smart device may already be connected to your headset. If the device is
playing music, on a phone call or using Cockpit Voice recorder, the headset
prevents unpairing for safety concerns. Please pause music, end the call, or
stop the Cockpit Voice recorder recording to return the device to “idle”. Once
this has been achieved, please attempt Bluetooth Pairing again.
25
FAQs
During take off or occasionally in cruise, I sometimes here a popping’ or low rumbling sound. What causes that…and how can I fix it? Some intermittent popping is typically a byproduct of noise or vibration that creates an instability in the ANR electronic performance. Noise levels, or cup movement, causes the ANR system to be chasing
noise’ that is intermittent and
hard to cancel. The instability can cause the artifact that sounds like
popping.
Headset fit is the best, most important tool to eliminate these occasional
noise artifacts. The two main reasons for this behavior would be the position
of the cups on your head and the seal around your ears.
1. Follow the fit instructions on page 6 to insure it is comfortably
positioned and high enough to not rest to much on your jaw. If you are
consistently having this popping’ problem, call and request a taller headpad. 2\. Try to ensure the earlobe is fully
inside’ the cup and then minimize the
leaks that might occur around sunglass frames. Many are very flat but non-
aviator versions might have significant thickness in the frames. To test for
whether the seal is good, press in slightly on the cup (during any popping)
and see if it goes away.
If additional help is still needed, please reach out to our Customer Service
line and we can provide more customized solutions.
26
FAQs
The ear cups are resting on the tops of my ears, which is uncomfortable. How
can I adjust my ear cups for the best possible fit?
To center your ears within the ear cups, a taller head pad should solve this
problem. This will move the ear cups further up the side of your head so you
can center your ears within the cups.
Order a complimentary tall head pad (Part No. A484) by calling Customer
Service at 800-332- 2421, or email our Sales department at
sales@Lightspeedaviation.com. You will need to provide your headset serial
number.
Where can I find my product serial number?
The Delta Zulu serial number (a small, white, barcode sticker with numbers) is
located on the headset underneath the head pad on the inner radius of the
headband. Remove the head pad to reveal the serial number. Simply pinch the
cushioned part of the head pad, pull down and it will snap out.
When I make a cell phone call, I can’t hear the person I`m calling. What’s the
problem?
Always disable ComPriority before making cell phone calls because the other
party will be muted. When activating the ComPriority button, an audible
message will report the function is “enabled” or “disabled”.
27
FAQs
My Delta Zulu seems to have a higher voice threshold to trigger communication.
I have to speak more loudly, or position the mic closer to my mouth, to break
squelch. Compared to my Zulu 2 or Zulu 3, is that true? What can I do to
improve this?
The Mic and pre-amp on the Delta Zulu mic was modified to create less
background noise when you break squelch and speak. It creates a quieter flying
experience for all attached to your ICS system. Used individually, you will
naturally compensate for that with an adjustment to your squelch setting.
While that is a positive for overall system noise reduction, some people will
experience the difficulty you described.
To ensure you gain the benefits of this additional quieting performance,
please do the following IF your other headsets are from Lightspeed Aviation:
1. On the NON-Delta Zulu models, remove the mic muff and then remove
(carefully, they are easy to lose!) the small black cap on the back side of
the microphone holder.
2. With a small, jeweler’s flathead screw driver, insert it into the slot’ and turn the internal gain potentiometer inside counter clockwise 1
Hour’
(like from the 11:00 position to 10:00).
3. Re-attached the black cap and try it out in your plane. I suspect it will
have largely equalized the squelch setting that will work well for all your
headset.

FAQs
How do I ensure that I am matching the Stereo/ Mono Setting to my Audio Panel?
The Stereo/Mono DIP switch setting should match the signal from your audio
panel. Delta Zulu is shipped in Mono (the “on” position). Unless you are using
your intercom or Audio panel to provide Stereo music to listeners, there is no
reason to switch your dip switch settings to stereo. Bluetooth music will be
played in Stereo even with a “Mono” setting.
How do I change a DIP Switch Setting? DIP switches are factory set to match
most aircraft audio panels. To change a DIP Switch setting:
1. Slide off the battery cartridge to reveal the DIP switch.
2. Use a small pointed object (such as a wood toothpick) to slide the DIP
switch to ON or OFF.
STEREO should be used for a stereo panel and MONO for a mono panel.
Generally no changes are needed to deliver optimal performance in most
aircraft. Certain audio panels require the portable units to be set to the
Stereo position. Please refer to the list provided on our Website FAQ’s.

Does it really matter if I register my headset?
Absolutely! Registering your headset will assure quick and efficient
processing of any repair or accessory purchases that you may need. If you
purchased your Delta Zulu headset directly from Lightspeed, your headset is
already registered with us.
You will need your serial number to register your headset or make a request
for warranty repair.
What is the warranty for a new headset? Lightspeed Aviation, Inc. has a 7-year
limited warranty for new Zulu series headsets.
How long do the ear seals, head pads, and mic muffs last? To ensure peak ANR
performance and comfort, replace the ear seals, head pads, and mic muffs every
18 months. These are wear items that are not covered by the Lightspeed
warranty and are available for purchase on our website at
LightspeedAviation.com/Accessories.
FAQs
In addition to Bluetooth, how do I connect my music player to the Delta Zulu
headset? To connect a music player to the Delta Zulu auxiliary input jack, use
an appropriate UAC cord. To adjust the volume on a device connected using the
auxiliary input jack, use the controls on the connected device.
What kinds of batteries are recommended in the battery pack? Easy to replace
battery packs give you the option of using AA batteries or the included
rechargeable lithium ion battery pack, your choice.

Warranty Information
7-Year Limited Warranty for New Aviation Headsets Sold by Lightspeed Aviation,
Inc. Lightspeed Aviation, Inc. (“LSA”) warrants that the new aviation headset
sold by LSA (“New Headset”) is free from all material defects in workmanship
and materials. For the New Headset, all warranties provided by LSA and all
implied warranties imposed by law are limited to a 7-year period, beginning on
the purchase date shown on the New Headset’s sales receipt (“Warranty
Period”). This 7-year Limited Warranty (“Limited Warranty”) is provided solely
for the benefit of the initial purchaser of the New Headset (“Purchaser”), and
it excludes all 3rd parties, including distributors, dealers, retailers,
subsequent owners, and other users of the New Headset. This Limited Warranty
is not assignable and remains in full force and effect during the Warranty
Period, but only if the New Headset: (a) has been properly maintained; (b) has
not been abused or misused; and (c) has not been repaired, altered, or
modified without LSA’s approval.
This Limited Warranty specifically excludes all taxes, shipping costs, and
problems relating to any: (1) repair, alteration, or modification not approved
by LSA; (2) abuse or failure to properly maintain the New Headset; (3) faulty
workmanship by any person, except LSA or its approved agent; (4) operation of
the New Headset, except as specified in its operating manual; (5) ordinary
wear and tear; or (6) finish and appearance item. For each claim made under
this Limited Warranty (“Claim”), Purchaser must, within 10 days of discovering
a New Headset problem indicating a breach of this Limited Warranty, deliver to
LSA a written notice that explains in detail the New Headset’s specific
defect, that shows proof of Purchaser’s purchase of the New Headset before the
end of the Warranty Period, and that shows proof that this Limited Warranty
applies to the New Headset. LSA or its agent may investigate any Claim. For
each Claim, LSA may, in its sole discretion, choose any of the following
exclusive remedies: (I) repair or replace the New Headset or any part thereof,
without charge to Purchaser, but first Purchaser must return the New Headset
to LSA’s authorized repair facility, pre-paying all shipping charges, and
Purchaser must accept the same as repaired or replaced at the facility’s
location (i.e., FOB the facility) within 10 days of the date of LSA’s
completion notice sent to Purchaser, or else LSA will deem the New Headset
abandoned, in which case LSA may keep, sell, or otherwise discard it; or (II)
refund the New Headset’s purchase price to Purchaser.

Without paying any amount to Purchaser, LSA may keep, sell, or otherwise discard all replaced New Headsets and parts thereof and all New Headsets where LSA has refunded the purchase price to Purchaser. In repairing or replacing any New Headset, LSA may, in its sole discretion, use new, used, or reconditioned parts or provide a refurbished used headset as a replacement. In connection therewith, LSA warrants that all new, used, or reconditioned parts or refurbished used headsets will be free from all material defects in workmanship and materials during the Warranty Period and for a period of up to 90 days thereafter, but only to the extent that such event occurs during the final 90 days of the Warranty Period. LSA may, in its sole discretion, (i) establish separate, additional, non-warranty repair and replacement programs for any new or used headset (“NonWarranty Service Programs”), (ii) the Non- Warranty Service Programs may cover any time period, before or after any Warranty Period has expired, and (iii) charge any amount and impose any term with respect to any Non-Warranty Service Program. For Non-Warranty Service Programs, LSA warrants that all new, used, reconditioned, or refurbished parts and headsets used to repair or replace any headset will be free from all material defects in workmanship and materials, but only for a limited period of 90 days thereafter. Purchaser acknowledges that used or reconditioned parts may be used to repair any new or used headset, and that a refurbished used headset may be provided as a replacement for any new or used headset.
