ANT/®®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 openedin 1959. (CB also includes a Class A citizens bandand 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 WarningsAll transmitter adjustments other than thosesupplied by the manufacturer as front paneloperating controls, must be made by, or underthe 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 regulationsof 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.What’s Included with Your 29 LTD BT1.

InstallationInstallationLocation32Mounting andConnectionMounting and ConnectionHold the radio with the mounting bracketin the exact desired location. If there is nointerference, remove the bracket and useit as a template to mark the location forthe mounting 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 inthe universal mounting bracketby two thumbscrews whichallow for adjustment at aconvenient angle.The bracket includes twoself-tapping screws and starwashers.The mounting mustbe mechanically strong,conveniently located.continuedDrill the holes and secure the bracket.21Connect the antenna cable plug to thereceptacle marked “ANT” on the backof the unit.329LTDBT_MANL.qxd:29 LTD BT 2/20/08 2:19 PM Page 8
InstallationInstallation54NoteConnecting to an accessoryfuse prevents the unit frombeing left on accidentally, andalso permits 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).A negatively groundedvehicle has 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 sideof the vehicle.This is usually the chassis. Anyconvenient location with a good electricalcontact (remove paint) may be used.45Plug power cable into back of unit marked“Power”. Be sure to observe polarity markings.Mount the microphonebracket on either sideof the unit (driver’s left)using two screwssupplied. Bracket shouldbe placed under the dashso microphone is readilyaccessible.67Attach the 6-pin microphone cable toreceptacle, on the front of unit and install uniton bracket securely.829LTDBT_MANL.qxd:29 LTD BT 2/20/08 2:19 PM Page 10
Ignition Noise InterferenceAntennasUse 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 BT 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 speakto a 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 Antenna7NoteFor optimum performancein passenger cars the idealantenna location is on thecenter of the roof. Secondchoice is on the centerof the trunk.NoteBecause many newer trucksfeature fiberglass door skins,the outside mirror must begrounded to the chassis via aground strap when antenna ismounted on the mirror bracket.Note3-way CombinationAntennas 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”CB antenna. Call 773-889-3087for further information.61A standard antenna connector is providedon the transceiver for easy connection.29LTDBT_MANL.qxd:29 LTD BT 2/20/08 2:19 PM Page 12
