Installation
Note
The transceiver is held in the
universal mounting bracket by
two thumbscrews which allow
for adjustment at a convenient
angle.
Location
Plan a location of the transceiver and microphone
bracket before starting the installation.
Select a location that is convenient for operation, yet
does not interfere with the driver or the passenger.
The transceiver is usually mounted to the underside of
the dash with the microphone bracket beside it.
Mounting and Connection
1
Hold the radio with the mounting bracket in the
exact desired location. If there is no interference,
remove the bracket and use it as a template to
mark the location for the mounting screws.
Installation
ANT
EXT MIC EXT. PTT EXT.SP.
+POWER–
The bracket includes two
self-tapping screws and star
washers. The mounting must
be mechanically strong and
conveniently located.
2
Drill the pilot and secure the bracket.
3
Connect the antenna cable plug to the receptacle
marked “ANT” on the back of the unit.

Note
Before installing the CB
radio, visually check the
vehicle’s battery connection
to determine which terminal
is positive or negative. A
negatively grounded vehicle
has its negative lead grounded
to the chassis.
Note
Connecting to an accessory
fuse prevents the unit from
being left on accidentally, and
also permits operating the unit
without running the engine
when the ignition is set to the
accessory position.
Note
When connected to an
accessory fuse, unit will self test
the emergency weather alert
automatically when ignition is
turned on. Turns itself on & off.
Note
The Clock/Timer feature needs
to be reset when connected to
a switched accessory fuse.
4
Connect the red lead of the DC power cord to an
accessory 12 volt fuse or directly to the battery.
Connect the black lead to the negative side of the
vehicle electrical system. This is usually the chassis.
5
Any convenient location with a good electrical
contact (remove paint) may be used.
Installation

6
Plug the power cable into the back of the unit
marked “Power”. Be sure to observe polarity
markings.
Mount the microphone

unit (driver’s left) using the

The bracket should be
placed under the dash so
the microphone is readily
accessible.

Antennas
Ignition Noise Interference
Note
For optimum performance
in passenger cars the ideal
antenna location is on the
center of the roof.
Second choice is on the center
of the trunk.
Note
Because many newer trucks
feature fiberglass door skins,
the outside mirror must be
grounded to the chassis via a
ground strap, if the antenna is
mounted on the mirror bracket.
Note
3-way Combination Antennas
are also available which allow
operation of all three bands
(AM-FM & CB), using a single
antenna. However, this type
of antenna usually results in
less than normal transmit and
receive range when compared
to a standard-type “Single
Band” CB antenna.
Call 773-889-3087 for further
information.
CB Antenna
Since the maximum allowable power output of the
transmitter is limited by the FCC, the antenna is critical
in affecting the transmission distance. Only a properly
matched antenna system will allow maximum power
output. Loaded type antenna models are highly recommended for most installations. For models with Weather
Feature (WX), a Dual Band (Center Load/Base Load)
antenna is recommended. Consult your Cobra dealer for
further details, or call 773.889.3087 and speak to a Cobra
representative.
ANT
1
A standard antenna connector is provided
on the transceiver for easy connection.
EXT MIC EXT. PTT EXT.SP.
+POWER–
Use of a mobile receiver at low signal levels is normally
limited by the presence of electrical noise. The primary
source of noise in automobiles is from the alternator
and ignition system. Typically, when the signal level is
adequate, the background noise does not present a serious problem. Also, when extremely low level signals are
being received, the transceiver may be operated with the
vehicle’s engine turned off. The unit requires very little
current and therefore will not significantly discharge the
vehicle’s battery.
Even though the Cobra 29 LX MAX has an automatic noise
limiter, in some installations ignition interference
may be
high enough to make good communications challenging.
Many possibilities exist and variations between vehicles
require different solutions. Consult with your Cobra
dealer or radio technician for help in locating the source
of severe noise.
Marine Installation
The transceiver will not operate at maximum
efficiency in a boat without a ground plane, (unless it has
a steel hull). Before attempting installation , consult your
dealer for information regarding an adequate grounding
system and prevention of electrolysis between fittings in
the hull and water.

Calibrate for SWR (Standing Wave Ratio)
SWR calibration is done to properly adjust the length of
the antenna and to monitor the quality of the coaxial
cable and all RF connections.
This calibration is critical in order to achieve optimum

What You Should Know About Weather
If threatening weather is nearby, the National Weather
Service may broadcast a 10 second alert tone. This
tone will be heard through the CB, even if the CB/WX
Control is in the CB mode or the unit is turned off.
This enables you to monitor CB frequencies and still be
warned by the National Weather Service Emergency
Alert. When you hear the alert, press the CB/WX button in the WX mode. You will then be able to hear the
Weather Warning Broadcast.
Your 29 LX MAX has a special auto squelch circuit for
weather transmission which disables your squelch
control.

FCC regulations permit only “transmissions”
(one party to another) rather than “broadcasts”
(to a wide audience). Thus, advertising is not
allowed on CB Channels because that is “broadcasting.”
FCC Warnings
All transmitter adjustments other than those
supplied by the manufacturer as front panel
operating controls, must be made by, or under
the supervision of, the holder of an FCC-issued
General Radio-Telephone Operator’s License.
Replacement or substitution of transistors, regular diodes or other parts of a unique nature, with
parts other than those recommended by Cobra,
may cause violation of the technical regulations
of Part 95 of the FCC Rules, or violation of Type
Acceptance requirements of Part 2 of the Rules.
You should read and understand Part 95 (included
with this unit) of the FCC Rules and Regulations,
before operating your Cobra radio, even though
the FCC no longer requires you to obtain an operator’s license.
