Installation  
Note  
Connecting to an accessory fuse  
prevents the unit from being left  
on accidentally, and also  
permits operating the unit  
without running the engine.

Plug power cable into back of unit marked  
“Power. Be sure to observe polarity markings.  
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  
In positive ground vehicles the  
red wire goes to the chassis and  
the black wire is connected to  
the ignition switch.

In a negative grounded vehicle, connect the  
red lead of the DC power cord to an accessory  
12 volt fuse.  
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  
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.

Antennas  
CB Antenna  
Note  
Ignition Noise Interference  
Use of a mobile receiver at low signal levels is  
CB Antenna  
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.  
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  
maximum power output. Cobra loaded type  
antenna models are highly recommended for  
most installations. Consult your Cobra dealer for  
further details, or call 773.889.3087 and speak to  
a Cobra representative.  
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.  
Even though the Cobra 29 LTD CHR 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.  
Note  
Because many newer trucks  
feature fiberglass door skins, the  
outside mirror must be  
grounded to the chassis via a  
ground strap when antenna is  
mounted on the mirror bracket.  
1
A standard antenna connector is provided  
on the transceiver for easy connection.  
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-typeSingle BandCB  
antenna. Call 773-889-3087 for  
further information.  
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.

Calibrate for SWR (Standing Wave Ratio)  
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 performance.  
Note  
Calibration must be made in an  
open area (never in a garage).  
Vehicle doors must be closed.  
No one should be standing near  
the antenna. (See your antenna  
directions for more complete  
information).  
Note  
Antenna Indicator LED  
will illuminate when TX if  
SWR is high.
