Introduction
The
COM is an in ter COM system designed to allow communication
between both the driver, passengers and other cars through the Push To
Talk (PTT) and allow connection to a variety of equipment for off-road
recreation or racing.
The COM has engineered this model to provide greater audio quality
and provide a better experience for the user by eliminating background
engine noise and preventing excessive sound levels in the headsets.
Additionally, greater connectivity has been provided to accommodate
the increasing use of mobile phones and other audio devices in the car.
Thank you for purchasing this product, with care the unit should
give you good service. Please read these instructions carefully, by
doing so you will get full use of the unit and save a great deal of
frustration!

Fitting the headset parts to your helmet
Speakers – Carefully fit the speakers inside the helmet so that they align
exactly with your ear canal. The Velcro should stick to the helmet lining
or if not, you can glue or stitch the Velcro loop fabric in place. (See
helmet headset install video @ https://utvcom.com/thecom-tips-ticks/ )
Microphone (Full face helmets) – Place the mic in the mouth guard
as close to your lips as possible. The mic may be fastened by glue or
stitching the Velcro loop fabric in place.
Microphone (Practice headsets & boom mics) – Practice headset
and boom mics should be adjusted so that the mic is in line with your lips
and no more than half an inch from your lips for the greatest audio
performance. Note the further the mic is from your lips the more distant
your voice will be and the less amplified it will be to the co-drivers.
Microphone (Open face) – Shape the microphone arm base to the
shape of the helmet. Make sure that there are no gaps between the
microphone arm base and the helmet. Set the boom and mic up inside the
helmet so that the mic will be in-line with your lips. Note where the zip
tie clips will secure the boom to the inside hard surface of the helmet.
Wipe and clean the inside surface with a cloth to remove any dust and
make sure that the helmet is clean. Fasten the microphone arm base in
position on the helmet using the adhesive pad provided. The microphone
MUST NOT be more than ½ inch from your lips. For right hand drive
cars make sure that the driver’s microphone is fastened to the left side of

6
the helmet and the co-driver’s microphone is fastened to the right. (vice
versa for left hand drive cars).
All headsets IMPORTANT – The white clip should be fastened to the
side of the helmet to alleviate strain on the cables. If not used, premature
failure of the headset may occur.

7
Installing
The COM
Amplifier Unit – Mount The COM bracket between the driver and co-
driver on the rear roll bar, position so that cables and the headsets do not
obstruct operation of the vehicle and are kept clear of the steering wheel.
The unit should be fastened to a roll bar with the provided clamps or in
the case of an in-dash unit it should be mounted securely in the dash.
Connect the 12-volt power cord to a correct 12-volt power port. If you
decide to hardwire the unit it is recommended that both the hot and
ground wires be connected directly to the battery terminals to avoid
interference and the cables should NOT be run together with other vehicle
wiring. The hot wire should be fused with a 10 amp in-line fuse when
snipping the S2 power receptacle. In-dash units do not require an
additional in-line fuse.
Avoid proximity to pedals and other moving parts and use cable
grommets to avoid chaffing where cables pass through the bulkhead. You
must fit the fuse in the positive lead, directly after the positive terminal
.

Power switch – The right-hand switch on The COM switches
the unit on and off, push to the left to switch on.
Volume control –
The volume control on the Radio affects the
overall volume to Th
e COM users. It is very sensitive and should
be adjusted from minimum volume while someone else is
broadcasting. For best results we suggest setting the radio to the
local weather channel (see below common channels for weather
frequency) and slowly turn the radio volume clockwise until
desired volume is clear. Sometimes backing the volume on the
radio slightly will give a clearer communication from outside
signals. After the radio is set, fine tune the volume with the
individual volume controls found on the Int
er COM ( see below)
and the aviator headsets if purchased.
Individual Intercom Volume controls –
The driver’s side
volume control affects the overall volume to the driver’s side
headset plug and the co-driver (passenger) side volume control
affects the overall volume to the co-driver’s side headset plug.
Set these controls individually to give a comfortable level.

Automatic Volume Control
– The COM is equipped with
an automatic volume control or “limiter”. This will raise normal
speech levels to a constant level and prevent excessive volume in
the headset. This can be disabled if not required by switching off
the DIP switch marked LIMITER on the rear panel.
Rear Jumper Wire – There is one jumper wire on T he COM .
The rear jumper wire must be plugged in to communicate with
the intercom (amplifier).
If you would like to use the radio hand mic and the radio
independently of the intercom, you will need to unplug the rear
jumper wire from the radio and remove the front dust plug from
the front then plug in the hand mic. Once the rear jumper wire is
removed the internal speaker on the radio will automatically turn
on. Note that the volume on the radio will need to be increased
when operating the radio independently of the intercom. You
will need to re-connect the rear jumper wires before The
COM
will properly function as one unit.
The rear jumper wire is directional. Make sure the tip of the
jumper wire marked as “Radio” is plugged into the 25-watt
radio 3.5mm port that shows a headset symbol (the other port
is marked “Data” and is plugged with a dust protector from
the factory to prevent plugging the jumper wire in the wrong

12
port). The other end of the jumper wire is marked “Intercom”
and should only be plugged into the intercom. TheCOM will not
work properly unless the jumper wire is properly installed.
Noise Reduction - The COM is equipped with a noise
reduction system that will eliminate amplification of
background engine noise. The threshold at which this
discriminates between background noise and your voice can be
adjusted with the control on the rear panel marked NOISE
REDUCTION. Rotating this adjuster clockwise will require a
higher speech level to activate the microphone. Noise
reduction can be disabled if not required by switching off the
DIP switch marked “1” on the rear panel to the down position.
The noise reduction switch is switched off from the factory. To
turn it on switch the DIP switch marked “1” up then adjust the
control dial to the desired setting.
Switch on Forehead of The COM assembly –
The toggle
switch on the front is for the lights. “I” is for the single cargo
light in the back simply rock the switch to the “I” position. “II”
is for the dual cabin lights in the front and “O” is for off. To turn
off the lights rock the switch to the center position.

13
Transmit level setting - Make a call to another radio and
confirm that your voice can be heard in the remote radio. The
level of your voice can be adjusted by inserting a screwdriver in
the slot marked RADIO TX LEVEL, this can be reduced if your
voice is received at a particularly high or distorted level or it can
be increased if you voice is faint. (Note turning the TX up to
high may cause distortion on the receiving end of your
transmission).

Audio output – The 3.5mm socket marked AUDIO OUT on the
rear of the amplifier can be connected to a tape/mp3 recorder. The
speech of both crew members can then be recorded along with any
auxiliary input.
Audio input –The 3.5mm socket marked AUDIO IN on the
rear of the amplifier can be connected to auxiliary equipment
such as GPS
Mobile phone connection / Level setting – The 3.5mm
jack socket on the back of the amplifier marked “TEL” can be
connected to your mobile phone. (Suitable leads and adapters
can be purchased from Th
e COM or your local dealer). Adjust the
amplifier for normal operating levels and then make a call with
your phone and set the volume on the phone to give the required
level in the headsets. The small “DIP” switch marked
“Telephone RX” on the rear panel can be set to reduce or
increase the received level if required. A similar switch marked
“Telephone TX” can be used to set the microphone level into the
mobile phone. This can be switched ON to reduce the mic level
if excessive background noise or distortion is heard at the remote
phone and should be left OFF if your voice is too faint.

transmitting outside the
vehicle

15
Frequency coordination –
The radio has been programmed
with numerous frequencies (channels). Channels 1-7, 15-22 are
GMRS frequencies and are commonly used across the nation.
We ask you to be courteous and use good practices before
selecting a channel for your area. Listen first to see if someone
is using that channel. Do not interrupt or use offensive
language. For more local information seek out your local
frequency coordinator.
