Ideally you want to play the same music that you listened to earlier and go for a ride on your own
(between 0mph and your typical maximum speeds) and assess how the music level reacts at various
speeds, which depends on how you adjust the auto volume pre-set sensitivity control to compensate
for the ANS position relative to helmet noise.
Connect the 3 pole end of the music lead supplied into your music systems headset socket and plug
the 4 pole end into the hubs Aux 4 socket. Set the music to a comfortable level while stationary and
then go for a ride to see how the auto volume responds to varying speeds. Do not attempt to speak
during this test as we have deliberately set the VOX levels very high to prevent helmet noise from
accidently tripping the VOX so that it does not mute the music during this test.
If the automatic volume level goes up too high, too soon
then you need
reduce the sensitivity
by adjusting the Auto Volume pre-set sensitivity control
clockwise
by about
1
⁄
8
th turn at a time, and
try again.
If you end up with the auto volume pre-set sensitivity control set fully clockwise and the music level
still rises too high, too soon, then you need to reposition the ANS in the riders helmet so that it has
more protection from the wind/helmet noise (i.e. bury it deeper into the helmet lining) then start again
with the auto volume pre-set sensitivity control set in its central position and go for another ride and
adjust as required.
If the automatic volume level does not go up enough, or goes up too late
then you need to
increase the sensitivity
by adjusting the auto volume pre-set sensitivity control
anti-clockwise
by
about
1
⁄
8
th turn at a time, and try again.
If you end up with the auto volume pre-set sensitivity control set fully anti-clockwise and the music
level still does not go up enough, or goes up too late, then you need to reposition the ANS in the riders
helmet so that it is more exposed to helmet noise, then start again with the auto volume pre-set
sensitivity control set in its central position and go for another ride and adjust as required.
When you are happy with the way the auto volume control is working you should
note its position for
later reference
and can then set each users VOX controls as follows;
Setting the riders VOX pre-set sensitivity control
Start with the riders VOX sensitivity control turned all the way clockwise
(soft/easy/sensitive)
and go for a ride to see if the helmet noise at speed can false trigger the VOX. If it does, then slightly
turn the VOX control knob anti-clockwise (say about
1
⁄
8
of a turn at a time) and try it again. Keep doing
this until you have set the VOX such that helmet noise will not accidentally turn it on at speed when
you are not speaking.
Top Tips (9)
If the riders VOX activates while you are not speaking
, first check that you have blocked the
vents on the inside of the chin-bar of your full face helmet, as this not only prevents wind from
blowing directly onto the back of the microphone, it also forces more airflow up into the visor area
and so helps with demisting your visor. If using an open face helmet, ensue you have fitted the
optional Open Face Conversion Kit (OFCK) properly to the microphone. If so then the riders VOX pre-
set sensitivity control is set too low (too far clockwise) so please turn it
1
⁄
8
th turn anticlockwise at a
time (to set the VOX threshold higher) and go for another ride. If required keep doing this until the
riders VOX reliable stays off when not speaking.
If the riders VOX is hard to operate
, first check that you are properly positioning the microphone
and are using the LOUD-SPOT. (If using an open face helmet, ensue you have fitted the Open Face
Conversion Kit (OFCK) properly and the right way round to the microphone). If so then please turn
the rider VOX pre-set sensitivity control
1
⁄
8
th turn clockwise (to set the VOX threshold lower) and go
for another ride. If required keep doing this until the riders VOX is easy to speak to, without helmet
noise activating it when not speaking.
Please repeat this process with the passenger VOX pre-set sensitivity control
If after setting the rider and passenger VOX sensitivity controls you ever want to make any adjusts to
the Auto Volume pre-set sensitivity control, you will need to rebalance the rider and passengers VOX
pre-set sensitivity controls to suit.
Top Tips (10)
Remember to use the microphone loud spot. It is a good idea to set the VOX about 20mph (32kmh)
faster than you would normally travel so that head winds do not cause it to false trigger. A wind/draft
excluder is sometimes fitted under the chin bar of some helmets and this can help reduce excessive
wind noise at higher speeds thus allowing for a lower VOX setting. If your helmet does not have one
you can either buy them from some shops of make one. See www.autocom.co.uk for tips on how to
do this.
A low VOX setting will cause the music to keep muting and/or bike to bike transceiver to keep
transmitting when not speaking at speed, and this would prevent you from being able to receive bike
to bike communications. This is why it is very important to correctly set the VOX and why you must
find and use the microphone LOUD SPOT rather than reduce the VOX level to compensate. Remember
not having the master volume controls set any higher that required helps you to naturally speak louder
and so operate a higher VOX setting with less effort.
You may notice that you have to set the VOX sensitivity slightly higher for the passenger. This is normal
because the passenger receives more helmet noise, plus gets turbulence off the rider’s shoulders and
so normally requires a slightly higher VOX setting.
