Installation
Location
Location
Plan location of transceiver and microphone
bracket before starting the installation.
Select a location that is convenient for operation,
yet does not interfere with the driver or passenger.
The transceiver is usually mounted to the underside of the dash with the microphone bracket
beside it.
Mounting and
Connection
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.
2
Drill the holes and secure the bracket.
Note
The transceiver is held in the
universal mounting bracket by
two thumbscrews which allow
for adjustment at a convenient
angle.
The bracket includes two selftapping screws and star washers. The mounting must be
mechanically strong, conveniently located.

Installation
3
Connect the antenna cable plug to the receptacle marked “ANT” on the back of the unit.

Installation
Note
Before installing the CB radio,
visually check the vehicle’s
battery connection to determine which terminal, positive
or negative, is grounded (positive is the larger of the two)
to the engine block (or chassis). 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.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
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.
4
4
In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
5
Connect the black lead to the negative side
of the vehicle. This is usually the chassis. Any
convenient location with a good electrical
contact (remove paint) may be used.
Installation
6
Plug power cable into back of unit marked
“Power”. Be sure to observe polarity markings.
7
Mount the microphone
bracket on either side
of the unit (driver’s left)
using two screws supplied. Bracket should be
placed under the dash .
so microphone is readily
accessible.
Note
If microphone is not
connected, audio will not
be heard at speaker.
8
Attach the 4-pin microphone cable to .
receptacle on front of unit and install unit .
in bracket securely.

Antennas
CB Antenna
CB Antenna
Since the maximum allowable power output of
the transmitter is limited by the FCC, the antenna
is critical in affecting transmission distance. Only a
properly
matched antenna system will allow maxiNote
mum power output. Cobra loaded type antenna
For optimum performance in
models are highly recommended for most instalpassenger cars the ideal anten- lations. For models with Weather Feature (WX),
na location is on the center of
a Dual Band (Center Load/Base Load) antenna
the roof. Second choice is on the is recommended. Consult your Cobra dealer for
center of the trunk.
further details, or call 773.889.3087 and speak to a
Cobra representative.
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 773889-3087 for further information.
1 A standard antenna connector is provided .
on the transceiver for easy connection.
Marine Installation
The transceiver will not operate at maximum .
efficiency in a boat without a ground plate,
(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.
6
Ignition Noise Interference
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 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 LE has an automatic noise limiter, in some installations ignition
interference may be high enough to make good
communications impossible. Many possibilities
exist and variations between vehicles require .
different solutions. Consult your Cobra dealer or
a 2-way radio technician for help in locating the
source of a severe noise.

What You Should Know About Weather
Note
If you wish to receive a listing of NOAA ‘Weather Radio
Transmitter locations, contact
your nearest National Weather
Service Office.
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/PA button in the WX mode. You
will then be able to hear the Weather Warning
Broadcast.
Your 29 LX LE has a special auto squelch circuit
for weather transmission which disables your
squelch control.

What is Weather Radio?
NOAA Weather Radio (NWR) is a
service of the National Oceanic
and Atmospheric Administration
(NOAA), of the U.S. Department
of Commerce. 380 NWR stations are in operation by the
U.S. Government in addition to
several NWR stations that are
maintained by private interest
groups. The capability is to supplement warnings by sirens and
by commercial radio and television. The 10 National Weather
Channels provide full coverage to keep you informed of
weather conditions, 24 hours a
day, 7 days a week.
