4. Adjusting the Voice Tube

Place the voice tube near the corner of the mouth just below, but not directly in front of, your lips, as shown.

5. Adjusting the Clothing Clip

Attach the clothing clip to a part of your clothing at about chest level. Press the ends of the cable clamp to allow enough slack ??? approxi- mately six inches (15cm)??? between your headset and the clothing clip.

Try moving your head from side to side to ensure that you have allowed suf???cient cable slack between the headset and the clothing clip.

???Periodically wipe off the capsule and voice tube or boom using a soft cloth which may be dampened with water.

???Do Not use alcohol, cleaning solvents, or detergents on your headset.

6.Attaching the Headset to Glasses (optional mounting style)

The spring clip on either side of the capsule allows you to install your headset onto glasses. If your glasses have wire temples, you may order an eyeglass bow adapter to thicken the mounting base for the capsule and ensure a comfortable ???t, as shown. The bow adapter is not included with the MS50 aviation headset (order PN 10822-00).
