The microphone is mounted on the end of a stiff flexible boom so that you can carefully position it close, if not just
touching your lips. In order for it to stay in place it is best to wedge or tape the boom between the outer shell of the
helmet and the inner cheek pad so that the right amount of boom comes up between the outer shell and inner
cheek/chin bar area, into the visor area and then bends down at about 45 degrees so that the microphone is dead
centre to you lips.
You may find that when moving the helmet on or off your head for the first few times that the microphone/boom
catches your nose and so by slightly twisting the helmet while putting it on or off your head it will help to avoid this.
Avoid pressure directly to the front and back of the microphone covers. To move or adjust the microphone, please
hold it by the outer edges or rubber neck, making sure that the beige side of the fabric sits flat against your lips,
then fine tune the positioning for the critical loud spot.
The microphone fabric is likely to become contaminated in time due to damp, dust, lipstick etc. if so you need to
have it serviced by an Autocom trained specialist. Failure to do so may result in partial sound loss. These covers
are considered consumable parts and so should be expected to need servicing every one to three years.

The fabric is either taped or
elasticated over the polystyrene and
so it is easy to install the speakers
behind the lining.
Note that the wire should come out
of the speaker towards the back of
the helmet.
When replacing the cheek pads trap
the boom between the outer shell
and the inner cheek pad taking care
not to cut the speaker wire with the
cheek pads plastic tongue if it has
one. Tape or glue if required.
