Putting into operation

Putting into operation

To connect the cable to the headset microphone:

왘 Plug the connector into the socket.

왘 Slide the silicone tube onto the

connector.

The microphone can be worn on the left or right side of the mouth.
If you do not want to change sides, continue on page 7.

Changing the microphone position (left/right)

The neckband has a total of five clips which are
designed so that the microphone boom can be
worn on either side of the mouth.

NOTICE Damage to the microphone boom

The microphone boom can break or be impaired in
its function when you bend or turn it. Also avoid fre­quent alternate bendings close to the microphone
head as this can also damage the microphone boom
and possibly reduce the adjustability of the micro­phone.

왘 Only adjust the microphone boom as described in

this chapter.

Adjusting the microphone boom and the neckband

For best possible comfort and optimum fit of the headset micro­phone, the neckband and the microphone boom have to be
adjusted to properly fit your head.

NOTICE Damage to the microphone boom

The microphone boom can break or be impaired in
its function when you bend or turn it.

Positioning the microphone towards the corner of the mouth

To individually position the microphone:

왘 Push the microphone boom  in

backwards or forwards in the clips
so that the microphone is posi­tioned 2 to 3 cm from the corner
of the mouth. The further away
the microphone is from the
mouth, the less treble is picked
up.

Adjusting the neckband

The neckband is adjustable in width
and ensures an optimum fit.

왘 Change the length of the neck-

band by moving the ear hooks
until a snug but comfortable fit is
achieved.

Using the frequency response caps

The MZC 2 frequency response cap  allows you
to adjust the microphone’s sensitivity in the pres­ence area. The MZC 2 gives a treble boost of 4 dB
(see “Frequency response curve” on page 15).
Use this cap if the microphone cannot be posi­tioned close to the mouth, if the sound is too muf­fled or if you want to increase the speech intelli­gibility.

왘 Slip the MZC 2 frequency response cap  onto

the microphone until it locks into place with an
audible click.

An additional frequency response cap (MZC 1) is
available as accessory. The MZC 1 ensures a treble
boost of 2 dB.

왘 Slip the MZC 1 frequency response cap onto

the microphone until it locks into place with an
audible click.
