Remove the battery cover and batteries (disconnect power lead)
Remove the two Pozi-Drive screws from the back cover (A), and
carefully lift it off. This then reveals the white 9 pin AUX
connector on the main circuit board (B).
Carefully break off the blanking tab from inside the lid (C),
which previously covered the slot in the front panel. Then
orientate the interface lead’s white connector so that the
exposed crimp side of the connector faces forward as per picture
(D). Carefully align and press the connector plug into the white
9 pin Aux connector.
Carefully position the interface lead around the nearby black
fixing pillar and push the interface lead into the front panel slot.
Before replacing the lid, push the wires down so that they will
not be trapped between the black pillar and lid when it is
replaced. With the lid on and in place, check alignment around
the front panel etc before replacing the two Pozi-Drive screws
(A). refit the batteries (or bike power lead)
Connect the interface leads plug to the radio, making sure it is
fully plugged all the way in (fit the retaining clamp if one is
provided with the radio) and turn the radio on to about 50%
volume (E).
Count to 20 into your microphone and activate your VOX (your
own side-tone confirms this for you) the other radio should
receive your speech and they can then adjust their hand held
radios volume to a suitable level. Please use this setting as a
guide to set the volume on the radio connected to your hub,
BEFORE getting the other person to transmit back to you using
their hand held radio, and then when they transmit back to you,
you can readjust your radios volume if required.
You will notice two important things happening which you
have to understand and get used to working with in order to
perfect using the system.
1) When you speak and activate your VOX it instantly switches
on (as confirmed by your own side-tone) and the VOX
simultaneously switches your bike to bike radio from receive
mode (or standby) into transmit mode. (If your radio has a
transmit LED or indicator you will notice this activates almost
instantly when you speak and operate your VOX).
There is unfortunately a short delay between when this happens
and when your speech is actually heard through the other radios
speaker. This is because after receiving your transmission, the
other radio has to switch between battery saving/standby mode
into receive mode and then check and except the anti-
interference tone code before allowing the sound to be amplified
through the speaker. The result of this short delay is that when
you say something like “left at the lights” it may be heard as
“at the lights” to which the reply is “what about at the
lights”, which is heard as “about at the lights”, I think you get
the message (which is that you won’t) so to get over this you
must get used to always using a KEY WORD, (like you will hear
professionals such as the police use) for example; “OK… turn
left at the lights, OVER” this key word and a short pause will
ensure that your intended radio transmissions are heard in full,
likewise by saying the word OVER allows the other person to
know you have ended your communication and after a second
or two your VOX will then switch your radio from transmit back
to receive, so that they can then speak back to you.
2) When you stop speaking there is a (deliberately designed)
short delay before your VOX switches the radio back from
transmit mode to receive mode. This delay is the best
compromise between; staying on as long as possible to help
prevent any pauses during normal conversations causing the
system to think you have stopped speaking and returning the
radio back to receive mode halfway through your conversations
and; as short as possible so that when you do actually stop
speaking, the delay time for your radio to stop transmitting and
return to receive mode is minimal, so that the other bike/s can
then transmit back to you as quickly as possible.
It is often very beneficial to have an experienced third person
(with radio) about to monitor your first bike to bike use, so that
they can listen for any mistakes either of you make and help guide you with proper use. They will also
be able to hear if anyone is transmitting any electrical interference and help identify which bike is the
cause, and so help speed up any fault finding processes.
Top Tips (12)
When two metallic objects are struck (or rubbed) together near to a transmitting radio, it can
sometimes induce a electrical interference that is transmitted to the receiving radio. If you hear any
interference over the bike-to-bike radios, try removing your tool kit from the bike and make sure that
your bike drive chain is well lubricated to see if the interference is eliminated. If replacing the tool kit
re-introduces the interference, it is a good idea to individually wrap each tool in cling film etc. to stop
them rattling together while riding. You may experience a similar problem if you carry a lock and chain
under the bikes seat, especially if it is in close proximity to the bike to bike transceiver.
