HEADSET COMPONENTS

CONTROL MODULE OPTIONS

There are two options for the control module:

• Control module with Bluetooth capability
• Conventional control module

IMPORTANCE OF PROPER FIT

FIT THE HEADBAND

Proper fit is important both for comfort and optimal noise cancellation performance.

1. Using the left and right icons on the headband to orient the headset properly, rotate the side pads into position.
   
2. Place the headset on your head.
3. Adjust the headband so the side pads rest above your ears.
   

CHOOSE THE CORRECT STAYHEAR+ TIPS

For optimal audio performance, it is important to choose the correct size StayHear+ tip. Select the size that gives you the best comfort and fit in each ear. To determine the best fit, you may need to try all three sizes. You may need a different size for each ear.

NOTE: Without a properly fitting tip, the noise reduction and audio performance of the headset will be degraded. To test the fit, try speaking aloud wearing the headset while it's powered off. Make a low-pitched "eee" sound. Your voice should sound amplified and balanced in both ears, similar to when you plug your ears with your fingers. If not, try another tip size.

Each StayHear+ tip and earbud is marked with either an L or an R. Be sure to attach the left tip to the left earbud and the right tip to the right earbud.

FIT THE EARBUDS TO YOUR EAR

The StayHear+ tip allows the earbud to rest comfortably and securely in your ear. The tip wing fits just under your ear ridge.

1. Insert the earbud so the StayHear+ tip rests gently in the opening of the ear canal.
2. Tilt the earbud back and tuck the tip wing under the ear ridge until it is secure.

TIP: If the StayHear+ tips don't fit securely, choose a different size.

Single earbud use

When you want to use the headset with one earbud, you can stow the other earbud using the earbud storage hook on the back of the side pad.

CHANGE THE STAYHEAR+ TIPS

1. Holding the earbud, gently grasp the attached StayHear+ tip and peel it away from the earbud.
   
   
   To prevent tearing, grasp the StayHear+ tip by its base. Do NOT pull on the tip wing.
2. Align the opening of the new StayHear+ tip with the earbud nozzle and rotate the tip onto the nozzle. Press the base of the tip until it clicks securely into place.
   

ADJUST THE MICROPHONE

NOTE: By default, the reversible microphone ships from the factory attached to the left side of the headset. If you want to move the microphone to the other side of the headset, see "Microphone Placement".

1. Grasp the microphone base, and adjust the boom so the microphone is level with your mouth.
   
   Microphone placement is important for clear communication. It can rotate 300°. Do NOT force the microphone beyond the intended rotation or damage could occur.
   
2. Position the microphone so it is 0.5" (12.7 mm) from your lips, and the white surface on the base is facing your mouth.
   NOTES:
   • If necessary, twist the microphone base to rotate the microphone into position.
   • The microphone should not be touching your lips.
     
3. Test the headset before flight.

CONDITIONS RELATED TO FIT

In very loud conditions, such as during takeoff, you may experience a brief reduction in noise cancellation as the headset compensates for a momentary pressure change. If this continues when the sound level returns to normal, see "Acoustic Noise Cancellation". If it persists, see "Troubleshooting".

A low rumbling sound or frequent, brief losses of noise cancellation may indicate an improper fit or blocked earbud ports. See "Choose the correct StayHear+ tips" for information on proper fit or "Clean the headset" for instructions on removing blockages.

During a long flight, you may feel a slight pressure point, which can be relieved by adjusting the headband position.
