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’s necessary to have a solid seal around your entire ear combined with a symmetrical t on your head.

The following tips will assist in achieving the proper t.

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.

Page 7

C. Position the microphone  inch from your

mouth, with the gain adjustment cap facing away from you (visible when you remove the mic mu).

Note: The microphone will not transmit unless plugged into an intercom.

Battery Installation

The Sierra headset requires two AA batteries (included). Use alkaline or lithium 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 ashes GREEN when

charged batteries are in use and the power is on.

C. When batteries begin to

run low the power LED ashes red.

Battery/DIP switch door

Stereo/mono switch

Getting Started

This side of the microphone should face away from you.

Page 8

If the LED ashes red during ight 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 signicantly reduce battery life. Under quiet conditions Sierra will auto shut o

approximately ve minutes after the headset is removed from your head.

The Controller

A. Power indicator LED: Flashes green when

power is supplied to Sierra 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 Sierra on; press and hold to turn Sierra o. 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 aect the volume of auxiliary devices.

D. Bluetooth indicator LED: Flashes blue

when Bluetooth mode is on and red when Bluetooth is being turned o. In pairing mode, ashes alternating red and blue.

E. Bluetooth button: Turns on and o the

Bluetooth signal and controls Bluetoothconnected devices.

F. Auxiliary input jack: Provides a wired input

for audio devices only (not cell phones).

G. Bluetooth volume buttons: Controls the

volume of Bluetooth devices.

H. ComPriority button: Quiets music and audio

from auxiliary devices during radio communications. Does not aect cell phone calls.

Using Your Sierra Headset

Turning ON and OFF

ON: Press the power button once to turn on the headset. The green power LED ashes 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 o.

Sierra will auto shut o approximately ve minutes after removing the headset and under quiet conditions.

The power LED ashes red when batteries are low; see Battery Installation, on page 5.

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 aect auxiliary devices, so you can enjoy auxiliary audio in stereo regardless of how the Stereo/Mono DIP switch is set.

Setting the DIP Switch

The DIP switch is factory set to match most aircraft audio panels. To change a DIP switch setting open the controller battery compartment door. Use a small pointed object like a wood

Page 11

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

ComPriority

ComPriority is turned on or off by the bottommost controller button. With ComPriority on and when radio communications are detected, the volume of auxiliary devices will be significantly reduced.

To enable ComPriority, 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, on page 9. If enabled your auxiliary music will decrease when you start to talk.

Note: ComPriority does not aect cell phone calls.

Wired Auxiliary Devices

To connect a music player to Sierra’s auxiliary input jack, use the cord provided.

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

Cell phone capability works only when connected via Bluetooth, not through the auxiliary input jack.

Note: Sierra will not stream music wirelessly.

Bluetooth and Cell Phones

Connecting Bluetooth Cell Phones for the First Time

Before using a Bluetooth cell phone for the rst time with Sierra it must be “paired” or electronically connected.

To pair a Bluetooth cell phone with Sierra:

1. Turn on the headset and verify the green LED is ashing. Make sure Sierra’s Bluetooth mode is turned o. Blue or red ashes from the Bluetooth LED should not be present (see “Bluetooth Mode—ON and OFF”, page 11).

2. Press and hold the Sierra Bluetooth button for about ve to ten seconds or until the Bluetooth LED continually ashes red and

blue. This indicates the Sierra 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.

3. With Sierra in pairing mode, follow the menu prompts on your Bluetooth phone directing it to look for Bluetooth devices.

4. Select Lightspeed-V### (numbers may vary) on your Bluetooth phone from the list of found devices

5. If asked to enter a password or PIN, enter 0000

Your cell phone should now be paired and ready for continued use with Sierra.

Page 13

Bluetooth Mode—ON and OFF

ON: With Sierra turned ON, press and hold the Bluetooth button; see page 7, until you hear a high tone and the Bluetooth indicator LED ashes three blue pulses. For rst time pairing see instructions on this page.

OFF: Press and hold Sierra’s Bluetooth button for about three seconds until a high tone is emitted and the Bluetooth indicator LED ashes three red pulses.

Note: The Bluetooth feature must be turned ON for Bluetooth connected devices to correctly function.

When you turn on the Sierra Bluetooth mode it will connect to the most recently paired device. Most Bluetooth cell phones connect to Sierra 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).

Note: The microphone will not transmit unless plugged into an intercom.

Note: Sierra will not stream music wirelessly.

Bluetooth Features

Depending on the Bluetooth prole of the phone, you can use Sierra’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 (Sierra’s + and – buttons) to adjust the volume.

Note: Cell Phone capability works only when connected via Bluetooth.

Why do I hear radio communications in only one ear?

Sierra’s Stereo/Mono DIP switch is probably set to Stereo while your audio panel is transmitting a mono signal. To x this, change Sierra’s Stereo/ Mono DIP switch to Mono. This setting does not aect 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 Sierra 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 for the First Time,” on page 10).

Why doesn’t my Bluetooth phone accept Sierra’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 for the First Time,” on page 10).

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 Sierra controller and headset when making calls.

FAQs

Page 16

FAQs

When ying 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.

Where is my product serial number?

The serial number (a small, white, bar-code sticker with numbers) can be found on the headset underneath the head pad. The head pad, located on the inner radius of the headband, must be removed to reveal the serial number. Simply pinch the cushioned part of the head pad, pull down and it will snap out.

Page 17

Peak Performance Tips

• Start with an excellent t—see “Fitting your headset,” on page 4.

• Set Sierra’s Stereo/Mono DIP switch to match the signal from your audio panel; see “Matching Sierra’s Stereo/Mono setting to your audio panel signal,” on page 8.

• Keep cell phones at least 12 inches from the Sierra 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 Sierra’s auxiliary input jack and a cell phone by connecting via Bluetooth.

• Lightspeed recommends replacement of the soft goods on your headset (ear seals, head pads and mic mus) every 18 months to ensure peak ANR performance and comfort. These are wear items and are not covered by the Lightspeed warranty and are available for purchase on our website at LightspeedAviation.com/content.cfm/Store

• When packing your headset into its case, place the mic just over the headband to avoid chang the boom.
