Note
Make certain that nothing will
interfere with the installation of
mounting screws, before drilling
holes.
Installation
Location
Mount your Cobra 75 ST EU Transceiver in a convenient location,
away from moisture and direct sunlight, in a location that will not
interfere with driving.
Cobra suggests mounting it either under the front seat or on the
fire wall.

Installation
1 Connect to 12V Dashborad Connection.
2For constant 12 volt source power, remove the cigarette lighter
plug and connect the red wire marked “BATT(+)” directly to the
positive side of the battery or to a connection on the fuse block
that is always on.
3Connect the black wire “Ground” to the negative side of the
car, usually the chassis. Any other location with good electrical
contact (paint removed) will also work.
Mounting and
Connections
Caution
Leavingthe75STEUonafter
your car is turned off can drain
your car battery when connected to
a constant 12 volt source. When
connected to an accessory 12 volt
source the unit will turn off when
vehicle is turned off.
Installation
Mounting and Connections
The Transceiver is held by two screws, permitting mounting in the
manner most convenient for your installation.
Mounting hardware is supplied for mounting the Transceiver. The
mounting must be mechanically strong and also provide a good
electrical connection to the chassis of the vehicle. Proceed as
follows to mount junction box:
1After you have determined the most convenient location in your
vehicle, hold the Cobra 75 ST EU Transceiver in the exact
location desired. If nothing will interfere with mounting it in the
desired position, use the Transceiver as a template to mark
the location for the mounting screws. Before drilling the holes,
make sure nothing will interfere with the installation of the
mounting screws.
2Connect the antenna cable connector to the antenna
receptacle on the unit. Most CB antennas are terminated with
a type PL-259 plug and mate with the receptacle.
3Connect the control unit to the front connector.

CB Antenna
For the most reliable operation and
maximum range, Cobra recommends using
a vertically polarized, quarter wave length
whip antenna (illustration A).
Shorter, loaded-type whips are adequate
when maximum range is not required
(illustration B).
CB Antenna
Installation
Note
Mobile installations (cars, trucks,
boats, etc) should be made only
with a non-directional antenna
system.
A standard antenna connector
(Type SO-239) is provided on the
ConnectorBoxforeasyconnection
to a standard PL-259 cable
termination.
Cobra antenna models are
recommended; see your local CB
dealer or order directly from Cobra
(see page 32).
Formaximumefficiencyinboat
installations, a ground plate is
required, unless the vessel has
a steel hull. Consult your CB
dealer for information regarding an
adequate grounding system.

Installation
External Speaker Installation
1Mount external speaker in desired location.
2Plug jack into the back of the Transceiver labeled EXT.
*The external speaker should have 4-8 ohms impedance and
be able to handle at least 4 watts.

Note
Internal speaker is muted when

Ignition Noise Interference
The alternator and ignition system in your vehicle may limit your
ability to receive low signal levels. Other noise interference can
be the result of several different installation variables. Consult
your Cobra dealer or a 2-way radio technician to help locate and
correct the source of severe noise interference.

Selecting a
Channel
Note
Sound clarity is measured by the
ratio of the signal level to the noise
level. The higher the signal-to-
noise ratio, the better the sound.
To Program Radio to Country of Usage
1Press and hold the ST (SoundTracker®)button.
2Turn power on to the radio. Release the SoundTracker®
button. The band ID will flash on default ID “EU” (first
use only).
3Press and release the Channel UP button for you ID
selection.

5 Press and release the SoundTracker® button again to set and
exit. The 75 ST EU will remember this setting after power
is turned off.
CB Antenna
Only a properly matched Antenna system will allow maximum
power output. In mobile installations (cars, trucks, boats, etc.), an
Antenna system that is non-directional should be used. When
installed in a boat, the transceiver will not operate at maximum
efficiency without a ground plate unless the vessel has a steel hull.
Before installing the transceiver in a boat, consult your dealer for
information regarding an adequate grounding system.

1Turn CB on by turning the volume control clockwise. Adjust
the volume to a comfortable level.
2 Before setting the squelch control on your radio, you must
select a channel that is not in use.
3 Turn on SoundTracker®.
4 To achieve the Desired Squelch Setting (DSS): Think of
your Squelch Control as a gate for incoming signals. If you
turn the Squelch Control fully clockwise, it raises the “squelch
gate” so high that no signals get through.

Setting Squelch
5 If you turn the squelch control fully counter-clockwise, it
lowers the “squelch gate” so low that everything gets through
- noise, weak signals and strong signals.
6 To set the “squelch gate” to the DSS-Desired Squelch
Setting, turn the squelch control counterclockwise until you
hear noise. Then turn the squelch control back clockwise just
until the noise stops. Now only strong signals get through.
The Desired Squelch Setting, (DSS) only allows actual
transmissions to come through. This effectively blocks out
unwanted noise.
