Important Instructions

Best performance is achieved by

• obtaining a good seal in the ear canal

• positioning the microphone close to the mouth

Earphone

Select an eartip that allows the earphone to seal the ear canal so
that it stays in position and the boom does not rotate downward
during use. Position the earphone securely in the ear. Moisten
the eartip if necessary to ease insertion.

Microphone

The microphone is highly directional. It will pick up your voice
within a narrow range and reject background noise that comes
from outside that range. To stay in this range,bend the boom so
that the microphone is within 1/2 inch of your mouth. Excessive
jaw movement can cause the eartip to work out of the ear if it is
not well sealed. Occasionally check the
fit of the eartip to ensure that the boom
remains in place and the microphone
does not move away from your mouth;
otherwise the microphone will reject
your voice and you will be difficult to hear.

Insertion

White eartip insertion

• For best results,moisten the eartip before insertion.

• Insert the eartip by pulling the ear outward and
upward. The eartip should seal deeply and
comfortably in the ear canal.

• Adjust the gooseneck so that the microphone
is within 1/2" of your mouth.

• Once properly inserted the microphone (boom)
should not move.

Foam eartip insertion

• Use a foam eartip if a good seal cannot be obtained with a
white eartip.

• Compress the foam at the end of the earphone by rolling
it between your thumb and forefinger before inserting it.
Hold the earphone in place for about 5 seconds while the
foam expands to create a tight seal.

Remove the eartip slowly with a twisting motion to break the seal.
