Mounting andConnection

Mounting and ConnectionHold the radio with the mounting bracket inthe exact desired location. If there is nointerference, remove the bracket and use it asa template to mark the location for themounting screws.

LocationPlan location of transceiver and microphonebracket 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 theunderside of the dash with the microphonebracket beside it.

NoteThe transceiver is held in the universal mounting bracketby two thumbscrews whichallow for adjustment at aconvenient angle.

The bracket includes two self-tapping screws and starwashers. The mounting must bemechanically strong,conveniently located.

Connect the antenna cable plug to thereceptacle marked “ANT” on the back of the unit.

InstallationInstallation

NoteConnecting to an accessory fuseprevents the unit from being lefton accidentally, and alsopermits operating the unitwithout running the engine.

NoteIn positive ground vehicles thered wire goes to the chassis andthe black wire is connected tothe ignition switch.

NoteBefore installing the CB radio,visually check the vehicle’sbattery connection todetermine which terminal,positive or negative, isgrounded (positive is thelarger of the two) to theengine block (or chassis). Anegatively grounded vehiclehas its negative leadgrounded to the chassis.

In a negative grounded vehicle, connect thered lead of the DC power cord to an accessory12 volt fuse.

Connect the black lead to the negative side ofthe vehicle. This is usually the chassis. Anyconvenient location with a good electricalcontact (remove paint) may be used.

5

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

Mount the microphonebracket on either side ofthe unit (driver’s left)using two screwssupplied. Bracket shouldbe placed under the dash so microphone is readilyaccessible.

Attach the 4-pin microphone cable to receptacle, on the front of unit and install uniton bracket securely.

Ignition Noise InterferenceAntennas

Use of a mobile receiver at low signal levels isnormally limited by the presence of electricalnoise. The primary source of noise in automobilesis from the alternator and ignition system.Typically, when signal level is adequate, thebackground noise does not present a seriousproblem. Also, when extremely low level signalsare being received, the transceiver may beoperated with the vehicle’s engine turned off. Theunit requires very little current and therefore willnot significantly discharge the vehicle’s battery.

Even though the Cobra 29 LTD CHR has anautomatic noise limiter, in some installationsignition interference may be high enough tomake good communications impossible. Manypossibilities exist and variations between vehiclesrequire different solutions. Consult your COBRAdealer or a 2-way radio technician for help inlocating the source of a severe noise.

CB AntennaSince the maximum allowable power output ofthe transmitter is limited by the FCC, the antennais critical in affecting transmission distance. Onlya properly matched antenna system will allowmaximum power output. Cobra loaded typeantenna models are highly recommended formost installations. Consult your Cobra dealer forfurther details, or call 773.889.3087 and speak toa Cobra representative.

Marine InstallationThe transceiver will not operate at maximumefficiency in a boat without a ground plate,(unless it has a steel hull). Before attemptinginstallation , consult your dealer for informationregarding an adequate grounding system andprevention of electrolysis between fittings in thehull and water.

CB Antenna

7

NoteFor optimum performance inpassenger cars the idealantenna location is on thecenter of the roof. Secondchoice is on thecenter of the trunk.

NoteBecause many newer trucks feature fiberglass door skins,the outside mirror must begrounded to the chassis via aground strap when antenna ismounted on the mirror bracket.

Note3-way Combination Antennas are also availablewhich allow operation of allthree bands (AM-FM & CB),using a single antenna.However, this type of antennausually results in less thannormal transmit and receiverange when compared to astandard-type “Single Band” CBantenna. Call 773-889-3087 forfurther information.

Calibrate for SWR (Standing Wave Ratio) SWR calibration is done to properly adjust thelength of the antenna and to monitor the qualityof the coaxial cable and all RF connections.This calibration is critical in order to achieveoptimum performance.

Select channel 20.

When switched to ANL the Automatic Noise Limiter is activated. This helps reduce noisecreated by the vehicle’s electronics.

When switched to NB/ANL position the RFNoise Blanker is also activated, providingincreased noise filtration.

Full clockwise rotation closes the gate allowing only very strong signals to enter.

Full counterclockwise rotation opens the“gate” allowing all signals in.

To achieve the Desired Squelch Setting (DSS),turn the Squelch control counterclockwiseuntil you hear noise. Now turn the controlclockwise just until the noise stops. This is theDSS setting.

The Citizens Band lies between the shortwavebroadcast and 10-meter Amateur radio bands,and was established by law in 1949. The Class Dtwo-way communications service was opened in1959. (CB also includes a Class A citizens band and Class C remote control frequencies.)

FCC RegulationsFCC regulations permit only “transmissions” (one party to another) rather than “broadcasts” (to a wide audience). Thus, advertising is notallowed 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-issuedgeneral Radio-Telephone Operator’s License.

Replacement or substitution of transistors, regulardiodes or other parts of a unique nature, withparts other than those recommended by Cobra,may cause violation of the technical regulations of Part 95 of the FCC Rules, or violation of TypeAcceptance requirements of Part 2 of the Rules.

You should read and understand Part 95 (includedwith this unit) of the FCC Rules and Regulations,before operating your Cobra radio, even thoughthe FCC no longer requires you to obtain anoperator’s license.
