Part 4. (Pro-7-Sport)

Superior quality and performance, expandable rider system.

Options for PHONE, MUSIC, BIKE to BIKE & PASSENGER

Before using this product please refer to the instructions for

any optional parts that you intend to use with this product

such as the bike power lead, for their installation and use.

The unit has three leads

1 lead with black 7-pin socket, 47 ¼ " (1200mm long) for use by the rider.

1 lead with black 7-pin socket, 33 ½ " (850mm long) for use by the passenger.

1 lead with grey 5-pin-socket, 15 ¾ " (400mm long) (Aux.1) for connecting to optional accessories, such as a

bike to bike transceiver. Note: A special Y lead can be plugged into the passenger lead for a third headset.

(Sidecar)

The front panel sockets

are for optional stereo music, mobile phone, & a remote handle bar speech high/low

control. The black shaft is the voice activated (VOX) pre-set control.

The Pro-7-Sport can be used as a portable with a PP3 (9 volt) battery

(Not supplied), or bike powered using an optional bike power lead

part 152 (PSU-M2). Note you will require headset extension leads

if you mount the system on the bike.

Pro-7-Sport (Part 4) Operation & use (as a rider – passenger intercom)

Basically the Pro-7-Sport is almost fully automatic and pre set for the optimum performance. Apart from

choosing any options for bike-bike, phone, music and/or passenger, a rider only has to choose how they want it

powered, set the VOX control to suit their helmet/bike and riding style, then plug in the headset/s and enjoy.

The key to easy operation

is understanding and using the microphone loud spot. With this understood and

used properly you can set the VOX control to about 70-75% (so that the flat is almost vertical to the left). This

will effectively give you a VOX setting for about 120-150mph, ensuring that the wind should never accidentally

turns the microphone/s on. BUT the only way your voice will produce enough energy to activate such a high

VOX setting is if you understand and use the microphone loud spot.

For portable use

, ensure that a fresh PP3 9-volt alkaline battery is correctly installed, taking care not to trap o

damage the wires when replacing the lid. In this mode the Pro-7-Sport automatically switches on when an

utocom headset is connected to the riders lead. This means that the power is automatically switched off each

time you unplug the rider’s headset, to save battery wastage. Please note that when using the optional bike

power lead that the unit is switched on and off via the bikes ignition key.

Taking care

when connecting or disconnecting the headsets to the Pro-7-Sport leads will ensure many years o

reliable operation. There is a flat on each connector to help you with alignment.

With the headsets correctly installed

and used as per the instructions, speak positively into the microphones

and you should hear your own voice through your own speakers, as well as being heard by the other person. I

not, you either need to adjust the VOX control to a lower setting (clockwise) or speak more positively, or

reposition the microphone/speakers (see headset section). Please note that with the VOX control turned all the

way clockwise, the microphones will be on all the time. With the VOX turned too far anticlockwise it will be hard

to operate the microphones unless you use the microphone loud spot. Finding the best VOX position takes a

little practice and time, as does getting used to hearing your own voice (side tone). Once you have set it

correctly and become used to using the system you will find that it will perform effectively and reliably.

By finding and using the microphone loud spot and projecting your voice through the microphone, you can

easily operate a much higher VOX setting. This is because the critical loud spot produces far more sound,

which is required to give a very good signal-to-noise ratio. Moving the microphone just 2-3mm away from the

loud spot can considerably reduce sound, and make it much harder to activate a higher VOX setting. The

temptation is to turn the VOX control clockwise to make it easier to talk to, but you must not do this. You must

understand and use the LOUD SPOT.

Always speak positively through the microphone. Most first time users will try the intercom in the house and of

course when you are in a quiet location you will naturally talk quietly, especially when you hear your own voice

through the ear pieces, this tends to make you talk even quieter, until you get used to it. With the VOX set as

described above you will find it difficult to keep the microphone’s on unless you try hard, using the loud spot

helps. Once you take the intercom out on the bike and put yourself in the noisy conditions within a helmet, you

will naturally talk a lot louder and find the system naturally much easier to operate. Once you have discovered

the principles, you will be able to properly set the VOX control to suit your riding speeds/helmets/bike. It is a

good idea to properly set the VOX to a speed of about 20+mph more than you normally ride at.

This allows for overtaking and head winds etc.

So if, for example, you normally ride @ 50mph

you should test and set up the VOX so that it

does not turn the microphone’s on @ 70+mph.

If you ride with a passenger then you need to set the VOX with both rider and passenger headsets in use. Get

to the desired speed (when and were is safe to do so) and if the microphones switch on, without speech, then

you need to set the VOX higher (by turning the VOX pre-set towards anticlockwise) Note: When the VOX knob

is flat/ horizontal/parallel to the label it will be set for about 60-70mph. With the flat vertical to the left of the knob

it will be set for about 150+mph. fully anticlockwise 180+mph. Fully clockwise and the microphones will be on

all the time. Therefore somewhere between horizontally flat and vertical to the left is where the VOX

should normally be set to suit typical speeds. This of course depends on your helmet noise

Incorrect VOX settings will cause the music to keep muting and/or bike-to-bike radio to keep transmitting,

cutting out any received transmissions, so a correctly set VOX is very important.

USING TRANSCEIVERS, SETTING THE VOX AND RADIO USE.

It is to be expected for some first time users

to have some difficulties, although it seems quite simple, and it is, there are some tricks it getting it right, so lets

go through a few pointers. Before riding

, set the system up on the bikes and practice some radio disciplines. It

can help if you practice on one bike while listening on the other transceiver with the volume turned up and the

leads unplugged from the side so that the transceiver speaker works. Someone else can talk back to you on

the other transceiver by pressing the PTT button on the side of the transceiver. If they listen carefully they will

hear the short delay after you finish speaking and before your VOX switches off and you stop transmitting. It is

important that you understand this VOX delay, as it is pointless trying to transmit back to someone else if they

are still transmitting. One has to have a short VOX delay so that the system reliably stays on during normal

speech, which may have short pauses and you don't want a transceiver bouncing between transmit and

receive, with the small losses of speech that you get in between.

When you first speak

you need to draw out the first word or use a key word to get things going. I always use

"OK when you get to the lights take a left, OVER" I always use OK at the start of a conversation because

although the VOX is instant, transceivers have to go from standby to transmit and also standby to receive, the

other end. So there is a 1/2 second or so delay. DON'T TURN LEFT may come over as TURN LEFT, so its

good practice to use a key work like OK then say what you want such as OK, DON'T TURN LEFT. Its also

good practice to say OVER when you have finished speaking, as if after saying OK TURN LEFT the other

person replied with OK, OK, they may well have transmitted over you trying to say something like AND THEN

TAKE THE NEXT RIGHT. Of course if you wait to hear OVER before giving a reply you can help avoid this, but

even a well seasoned user will occasionally jam, which is when two people transmit at the same time.
