Introduction 5
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 fit on your head. 4. Position the microphone 1∕8 inch from your mouth, with the gain adjustment cap facing away from you (visible when you remove the mic muff ). This side of the microphone should face away from you.
Getting Started 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 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.
Getting Started The controller A. Power indicator LED: Flashes green when power is supplied to Sierra and batteries are strong. Flashes red when batteries are low. E. Bluetooth button: Turns on and off the Bluetooth wireless technolgy signal and controls devices connected via Bluetooth wireless technology, including cell phones and music players. B.

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. Sierra 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 7.
Using Your Sierra Headset ComPriority™ ComPriority is turned on or off by the bottom-most 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 in the next section. If enabled, your auxiliary music volume will decrease when you start to talk.
Connecting Devices with Bluetooth Wireless Technology Connecting devices with Bluetooth wireless technology for the first time Before using a cell phone or other Bluetooth wireless technology enabled device for the first time with Sierra, it must be “paired” or electronically connected. To pair a Bluetooth wireless technology enabled cell phone with Sierra: 1. Turn on the headset and verify the green LED is flashing. Make sure Sierra’s Bluetooth mode is turned off.
Bluetooth Wireless Technology Bluetooth mode—ON and OFF ON: With Sierra turned ON, press and hold the Bluetooth button (see page 8) until you hear a high tone and the Bluetooth indicator LED flashes three blue pulses. For first time pairing see instructions on page 11. OFF: Press and hold Sierra’s Bluetooth button for about three seconds until a high tone is emitted and the Bluetooth indicator LED flashes three red pulses.
Bluetooth Wireless Technology Bluetooth wireless technology phone features Depending on the Bluetooth wireless technology profile 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.
FlightLink FlightLink is the first in-flight cockpit recording application for the iPad® and iPhone.® The free app works seamlessly with Sierra headsets to capture and retrieve all incoming and outgoing communications. Features • Record all activity over the intercom, as well as in-cabin conversation. • Playback the prior two seconds or two minutes. • Store your recording library. • Draw notes, codes, or diagrams on the convenient iPad scratchpad for reference.
FAQs Why do I hear radio communications in only one ear or weakly in both? Sierra’s Stereo/Mono DIP switch is probably set to Stereo while your audio panel is transmitting a mono signal. To fix this, change Sierra’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.
FAQs 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. 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.
Peak Performance Tips • Start with an excellent fit—see “Fitting your headset,” on page 6. • 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 9. • 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.
