Top Tips (4)
When installing the headset into the helmet place the helmet on a soft towel etc, so as to help stop
it sliding about and/or getting scratched. If you fit one helmet first, you can then test the installation
for sound quality/level and then when you think you have the speakers correctly positioned you can
compare it to the other headset that has not been installed. When you are completely happy with
the first helmet installation you can then install the second headset into your other helmet. If ever
passing an approved Autocom dealer you can ask them if you can compare your headset installation
with their ear-defender demo/test headsets in the shop. It is a good idea to do this at least once
every six months just to check your speakers haven’t move over time through putting the helmet
on and off.
Put the helmet on and try to work out exactly where the centre of each ear hole is relative to the straps
or any seams etc in the lining, and also while doing this try to find and mark the exact location of the
centre of your lips inside the chin pad with the helmet sat in its natural position. When you have
established these positions within the helmet you are then ready to start the headset installation/s.

You may notice that most peoples ear holes are between 1” and 1

” below the top of their ears, and
that most peoples top of their ears are about in-line with their eyebrows. If you look at someone’s
face through the helmets visor area, you can reference their eyebrow position and assist them with
working out the approximate position below this for their ear holes. If they can then also feel and
then reference the approximate horizontal position of their ear holes relative to the straps etc, it will
provide a good starting point for speaker positioning.
There are two main types of typical full face helmet designs
, one is a one part chin and cheek
pad design, per the illustration shown on the top of page 10, the other and more popular type is a three
part chin/cheek pad design per the illustration shown at the bottom of page 10. Most full face helmets
do not have the cheek pads glued in and are just a compression fit, which makes them much easier to
remove (although some are quite tight).
