Caution
In rare instances an eartip may come off in the ear canal when
removing the earpiece.If this should occur and the eartip cannot
be easily removed, it is recommended that you promptly contact
an audiologist or other medical professional. A professional can
use blunt tweezers to remove the eartip.
Consult an audiologist or physician if you have excessive ear
wax,difficulty inserting the eartips,or discomfort after
prolonged use.
Do not use at excessively loud levels.Research confirms that
earphones that seal the ear canal allow listeners to listen at
safer levels.Noise-induced hearing loss is a function of exposure
time, the average sound level and the peak of very loud sounds.
A sealed eartip and lower listening levels allow for longer
periods of safe listening.

Inse tion
Import nt: Sound quality and noise
isolation depend on a good eartip seal.
• Carefully insert the earpiece
while pulling up and out on the
back of the ear.
• Twist the earpiece while inserting,
until outside noise is blocked out.
• Position the earpiece for best fit and comfort.
• Bend the boom so the microphone is close to the mouth.
•3-fl nge e rtip: Moistening eases insertion.
•Fo m e rtip: Roll down or compress foam eartip before
inserting. Hold the eartip in place for about 5 seconds while
the foam expands to create a tight seal in the ear canal.
•Glider e rtip: Simply push into ear canal.
Removal
To avoid discomfort,remove the headset slowly with a twisting
motion to gradually break the seal.Open jaw slightly to equalize
pressure, because suction can occur when the eartip is removed.

earphone insertion go to

Selecting an Ea tip
The eartip that is most comfortable is the likely choice, but it
MUST SEA well in your ear. If you can easily hear others when
the volume is off,you don’t have a good seal. Twist it in deeper,
or choose another eartip.

radio frequency (RF) energy set by the Federal Communications
Commission of the U.S.Government.The FCC has established
criteria for the amount of radio frequency energy various products
may produce depending on their intended usage.This product has
been evaluated and found to comply with the FCC’s exposure
criteria.For body worn operation, the FCC RF exposure guidelines
were also met when used with the accessories supplied or
designed for this product.Use of other accessories may not ensure

1.This device may not cause harmful interference, and
2.This device must accept any interference received, including
interference that may cause undesired operation.These limits
are designed to provide reasonable protection against harmful
interference in a residential installation.Some equipment oper-
ates at frequencies that may cause interference to nearby TVs
and VCRs; to minimize or prevent such interference, the system
base should not be placed near or on top of a TV,PC monitor,or
VCR; and, if interference is experienced, moving the desk station
farther away from the TV or VCR will often reduce or eliminate
the interference.However,there is no guarantee that interfer-

does cause harmful interference to radio or television reception,
which can be determined by turning the system off and on,the
user is encouraged to try to correct the interference by one or
more of the following measures:
1.Increase the separation between the equipment and receiver.
2.Consult the dealer or an experienced radio TV technician for
