It is very important to properly set up and use these products as designed. Please do not make any

modifications or try to use these products with any non recommended products or in any other way than

described. DO NOT CUT OR MODIFY YOUR HELMETS

It is common sense and the law in some countries that the rider of a vehicle be in control at all times, which

includes the ability to hear other road users warnings. As such the rider should not have the music volume so

loud as to prevent this. SAFETY

should always be your first priority and is ultimately the responsibility of the

rider. Mounting the Pro-7-Sport on the bike is safer than having it on your person. Make sure that the quick

release connectors are free to quick release in the event of an emergency. Do not fix or tape them together.

You should set the VOX and/or make any other adjustments while stationary, never while in motion. Always

focus your attention to the riding and safety and do not use the Pro-7-Sport in such a way as to interfere with

this. The added ability to communicate with your fellow riders can improve safety, so become familiar with

using the system to provide warnings etc. Follow the instructions carefully and if in doubt consult your supplier.

The boom microphone has a critical loud spot, which the systems are tuned to and so this loud spot must

be understood and used properly, especially with our voice-activated systems (VOX).

Positioning of the two high quality speakers is critical for maximum performance and sound quality,

especially when using earplugs. Some earplugs can over attenuate the systems sound, especially if the

microphones and/or speakers are not correctly positioned or used as designed.

The Pro-7-Sport is splash resistant. NOTE in order to allow it to vent the unit is not completely waterproo

and so reasonable care should be used to protect it. As a portable it should be safe in a pocket or in the

Autocom carry case. When mounted on a bike it will normally sit under the back seat, near to the brake light.

void mounting it in places like the front fairing or by the wheels where water may be forced in at high speeds,

or direct spray from jet washers, (cover with plastic bag then remove afterwards such that the product can

breath).

The Pro-7-Sport battery lead is designed for 9 volts only. The battery clip is designed for a PP3 battery.

More than 9 volts will cause damage to the Pro-7-Sport. Less that 7.5 volts will cause the Pro-7-Sport not to

function correctly. For 12-volt operation use part 152 (when mounting the Pro-7-Sport on a bike), or part 155

when mounting the Pro-7-Sport in a tank bag etc, with either part 135 or part 156 mounted on the bike. DO

NOT ATTEMPT to make any other type of 12-volt connection to the Pro-7-Sport. Please ask your dealer for

more details.

Practise makes perfect and it’s much easier to practice while close together and not riding and worrying about

other things going on.

VOX, or voice activation, gives you several advantages. Apart from turning the microphones off when you are not

speaking. The VOX can automatically mute the music or make your transceiver transmit when you speak, giving

you hands free and safer operation.

Correct VOX

settings will make all the difference to a flowing two way conversation (one way at a time with bike-

bike) as the higher the VOX setting the quicker the switching off of the microphones which allows for faster return

transmissions. To help get reliable speech with the highest VOX setting one MUST set up and use the

microphones loud spot. Speaker positioning is also very important as with the speakers out of position the sound

level will be much lower, this will tend to make you turn the transceivers receive volume up and if too loud it will

cause VOX bounce to warn you that something is wrong and protect the speakers. VOX bounce is where the VOX

switches in and out during conversation normally because the incoming speech is set too loud (normally

associated with excessive transceiver volume, to compensate for incorrect speaker positioning or over attenuating

earplugs) To test this hold the speakers over your ears, turn the transceiver volume down and slowly turn it back

up to a comfortable level, then the VOX should not bounce.

Typical problems

are due to misunderstanding the importance of correct setting up; some users turn the VOX

setting too low (clockwise) to compensate for not properly using the microphone loud spot. With the VOX set too

low the microphone may accidentally switch on at higher speeds, causing your transceiver to transmit, which of

course you don't want to happen when trying to receive a transmission from the other bike.

Obviously the faster you go the more likely the helmet noise is to false trigger the VOX, which can cause you to

have break-up in conversations, but with a correct (higher anticlockwise) VOX setting, which is easily activated

when using the microphone LOUD SPOT, you will avoid false VOX operations at higher speeds

With correctly positioned speakers you will find you can turn the transceiver receive volume down, which will avoid

VOX bounce.

With practice your radio discipline will get better and you will avoid clipping the first part of the sentence by using a

key word such as OK, then educate the other users to not return comments until you have said OVER, Plus then

also allow a one or two second delay to allow your transceiver to switch back to receive before they return the

speech, remembering that they must start with a keyword or OK and again end with OVER.

DO NOT increase the transceiver, phone or music volume levels to compensate for incorrectly positioned

speakers, as doing so will impair quality and performance and may cause distortion and/or damage to the

speakers.

A wind/draft excluder is sometimes fitted under the chin of some helmets, which can help reduce wind pick-up,

thus allowing for lower VOX settings. Some helmets have a chin vents that blow straight through, as well as

sending some of the air to the inside of the visor. By blocking/taping the inside chin vent it helps prevent wind

blowing on the back of the microphone, allowing for a lower VOX setting and can also improve visor demisting.

Earplugs. Depending on how well you set the speaker positioning and use the microphone loud spot will depend

on how much sound level you will have at the ears. Extreme ear plugs, or earplugs that have high attenuation

levels will make it hard to hear even the best set-up, but low to average attenuation earplugs will work reasonably

well if your installation and use is good. Remember that for each decibel or dB of attenuation you effectively halve

the sound, so if its very good to start with you can afford to reduce it some. We recommend that you do not use

earplugs with more than 20dB attenuation, as much above this will be likely to cause you to want more volume,

which you cannot have. Remember it is already set to the optimum level.
