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 the ANR feature it is necessary to have a solid seal around your entire ear combined with a symmetrical fit on your head.
The following tips will assist you in achieving the proper fit.

A. Fit your ears entirely within the ear cups providing a solid seal.
B. Rest the headband lightly on top of your head with the right and left sliders extended to equal lengths.
C. Position the microphone 1/8 inch from your mouth.

Battery Installation
The standard Zulu.2, Zulu.2:CD and Zulu.2:C battery–powered headsets require 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 flashes GREEN when charged batteries are in use 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. 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 re- chargeable batteries or mixing battery types and brands.

Battery Life
A set of batteries can provide up to 40 hours of power. However, heavy Bluetooth usage can significantly reduce battery life. Under quiet conditions Zulu.2 will auto shut off approximately five minutes after the headset is removed from your head.

Controller

A. Power indicator LED: Flashes GREEN when power is supplied to Zulu.2 and batteries are strong. Flashes RED when batteries are low.
B. Power button: Powers on headset, turning on Active Noise Reduction (ANR). Press button once to turn Zulu.2 on; press and hold to turn Zulu.2 off. To toggle the LED brightness from bright to dim quickly press the power button twice.
C. Volume control: Controls audio panel volume with individual sliders for each ear. Does not affect the volume of auxiliary devices.
D. Bluetooth indicator LED: Flashes BLUE when Bluetooth mode is on and RED when Bluetooth is being turned off. In pairing mode, flashes alternating RED and BLUE.
E. Bluetooth power button: Turns on and off the Bluetooth signal and controls Bluetooth-connected devices.
F. Auxiliary input jack: Provides a wired input for audio and cell phone devices.
G. Bluetooth volume buttons: Controls the volume of Bluetooth devices.
H. Auto MusicMute button: When enabled, automati-cally quiets music and audio from auxiliary devices during radio communications.

Using Your Zulu.2 Headset

Turning ON and OFF

ON: Press the power button once to turn on the headset. The GREEN power LED flashes when power is supplied. Active Noise Reduction (ANR) is engaged when you turn on the headset.
OFF: Press and hold the power button until the GREEN power LED turns off.
Zulu.2 will auto shut off approximately five minutes after removing the headset and under quiet conditions.
The power LED flashes 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. For a stereo panel, best performance is gained by setting the headset for stereo. The same is also relevant to a mono panel. Incorrect settings result in communications being heard in only one ear. 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.

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.

Auto MusicMute
Auto MusicMute is turned on or off by the bottom-most controller button. With Auto MusicMute on and when radio communications are detected, the volume of auxiliary devices will be significantly reduced.
To enable Auto MusicMute, turn on the feature, plug into your intercom and talk into the headset microphone while playing music over a wired device; see Wired Auxiliary Devices. If enabled, your auxiliary music will decrease when you start to talk.

Wired Auxiliary Devices
Zulu.2’s wired auxiliary input allows you to connect to cell phones and to most audio devices. To connect a music player to Zulu.2’s auxiliary input jack, use the cord provided.

To adjust the volume on a device connected to Zulu.2’s auxiliary input jack, use the controls on the device itself.

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 like a wood toothpick to slide the DIP switch to ON or OFF depending on your preference.

Zulu.2 DIP Switch and Their Recommended Use

DIP switch	OFF position	ON position	Recommendations
Stereo/ Mono	Stereo	Mono— Factory setting	Affects audio from the panel only

and should be set to Mono in most cases. Set to Stereo only if you are using a stereo panel. If your audio panel produces a mono signal but the switch is set to Stereo, you will hear audio communications in only one ear.
Leave off| Leave set to OFF| | Test mode; for factory use only.
Cell mic bias— two switches that must both be in the same position| Cell mic bias off—Factory setting for helicopter and panel-powered headsets| Cell mic bias on—Factory setting for battery- powered airplane headset| Lets you make phone calls with the headset when it is not plugged into a cockpit audio panel. Available for battery-powered headsets only.

Note to helicopter pilots: The ON setting for these switches is incompatible with some 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.

DIP switch	OFF position	ON position	Recommendations
Noise gating	Factory setting		When enabled, Noise Gating eliminates a low

level threshold of sound (example: noisy intercoms).

Test before using to avoid missed communications

from softer radio signals.

Leave off| Leave set to OFF| | Test mode; for factory use only.

Bluetooth Devices

Zulu.2’s Bluetooth interface allows cell phone and stereo music streaming capability (A2DP).

Connecting Bluetooth Cell Phones for the First Time
Before using a Bluetooth cell phone for the first time with Zulu.2 it must be “paired” or electronically connected.

To pair a Bluetooth cell phone with Zulu.2:

Turn on the headset and verify the GREEN
LED is flashing. Make sure Zulu.2’s Bluetooth mode is turned OFF. BLUE or RED flashes from the Bluetooth LED should not be present (see “Bluetooth Mode—ON and OFF”, page 13).
Press and hold the Zulu.2 Bluetooth button for about five to ten seconds or until the Bluetooth LED continually flashes RED and BLUE. This indicates the Zulu.2 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.
With Zulu.2 in pairing mode, follow the menu prompts on your Bluetooth phone directing it to look for Bluetooth devices.
Select Lightspeed-V### (numbers may vary) on your Bluetooth phone from the list of found devices
If asked to enter a password or PIN, enter 0000

Your cell phone should now be paired and ready for continued use with Zulu.2.
When you turn on the Zulu.2 Bluetooth mode it will connect to the most recently paired device. Most Bluetooth cell phones connect to Zulu.2 automatically. If that doesn’t happen it may be necessary to use the cell phone menu of found devices to signify Lightspeed-V### (numbers may vary).

Bluetooth Features
Depending on the Bluetooth profile of the phone, you can use Zulu.2’s 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 the phone when it rings.
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 (Zulu.2’s + and – buttons) to adjust the volume.

Bluetooth Mode—ON and OFF

ON: With Zulu.2 turned ON, press and hold the Bluetooth button; see page 6, until you hear a high tone and the Bluetooth indicator LED flashes three BLUE pulses. For first time pairing see instructions on page 12.
OFF: Press and hold Zulu.2’s Bluetooth button for about three seconds until a high tone is emitted and the Bluetooth indicator LED flashes three RED pulses.
Note: The Bluetooth feature must be turned ON for Bluetooth connected devices to correctly function.

Peak Performance Tips

Start with an excellent fit—see “Fitting your headset,” on page 4.
Set Zulu.2’s Stereo/Mono DIP switch to match the signal from your audio panel (see “Matching Stereo/Mono Setting to an Audio Panel ” on page 8).
Keep cell phones at least 12 inches from the Zulu.2 controller and headset when making call to reduce static noise during phone calls.
To conserve battery life, turn off Bluetooth mode when not in use.
You can use auxiliary devices such as a music player by connecting to Zulu.2’s auxiliary input jack and a cell phone by connecting via Bluetooth, or through the standard 2.5mm cell phone cable provided.
Lightspeed recommends replacement of the soft goods on your headset (ear seals, head pads and mic muffs) every 18 months to ensure peak ANR performance and comfort. These are wear items that are not covered by the Lightspeed warranty and are available for purchase on our website at LightspeedAviation.com/content.cfm/Store

FAQ’s

Why do I hear radio communications in only one ear?

Zulu.2’s Stereo/Mono DIP switch is probably set to Stereo while your audio panel is transmitting a mono signal. To fix this, change Zulu.2’s Stereo/Mono DIP switch to Mono. 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.

When pairing Zulu.2 with my Bluetooth phone, why does my 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; (see “Connecting Bluetooth Cell Phones,” on page 12).

Why doesn’t my Bluetooth phone accept Zulu.2’s 0000 passcode?

Your headset may not be in pairing mode. Some phones prompt for a pass code without checking for pairing mode. When the phone cannot pair with the headset, it rejects the passcode. To enter pairing mode, you must start with Bluetooth mode turned fully OFF (see “Connecting Bluetooth Cell Phones,” 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 Zulu.2 controller and headset when making calls.

When flying 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.
