5A. Installation Instructions For Most Modular
Flip-Up & Open-Face Style Helmets
IMPORTANT NOTE: Modern day helmets can present special challenges
for wireless headset installation. If you do not feel you are up to the task,
you may send your “un-modified” helmet to our factory in Tucson and we
will perform the installation for a nominal fee. (Please call first to ensure
that we are able to install a headset into your particular brand/model of
helmet.)
Installation into most Modular Flip-Up and Open-Face
Style Helmets
1. Most modular flip-up and/or open-face style helmets have cheek pads
that can be removed. Carefully do so at this time, paying special atten-
tion not to break or damage any of the polystyrene parts. (It is impor-
tant to have the helmet fit and feel the same after the speakers are
mounted as it did before the headset was installed.)
2. Using a headset speaker as a guide, mark the circular pieces of styrene
to be removed from the back of the ear area of the nose section or the
cheek pad.
See Figure 3
. With an Exacto® knife, cut a hole slightly
smaller than the speaker so that the speaker will “press fit” into the
hole without damaging the styrene. An airtight seal is necessary to
preserve bass response as the sound pressure from the back of the
speaker housing should not be allowed to mix with the sound pressure
from the front. Also, be careful not to cut or damage the fabric lining.
3. Position the boom microphone on the left in side of the helmet so that
the microphone lines up with the wearer’s mouth. Then remove the
backing from the tape on the pre-gummed mounting square and press
it into place inside the helmet. (Note: this area should be cleaned with
rubbing alcohol prior to sticking the microphone in place.)
4. Slide the mounting clamp into the proper position on the left bottom
edge of the helmet, peel the backing off the double-sided tape, press
the clamp-on mounting plate assembly firmly into place, then Install the
BT-05 module on to the mounting-plate.
See Figure 4
.
5. Using the enclosed wooden tool, carefully push the speaker wires into
the gap between the helmet liner and shell.
