Operating Instructions for your Cobra 29 LTD HD LE

Edition

CB Radio

The Citizens Band lies between the shortwave broadcast and 10-meter Amateur radio bands, and was established by law in 1949.The Class D two-way communications service was opened in

1959. (CB also includes a Class A citizens band and Class C remote control frequencies.)

FCC Regulations

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.

Installation

Location

Mounting and Connection

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.

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.

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 self-tapping screws and star washers.The mounting must be mechanically strong, conveniently located.

continued

Drill the holes and secure the bracket.

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

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.

Note

In positive ground vehicles the red wire goes to the chassis and the black wire is connected to the ignition switch.

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.

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

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.

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.

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

Ignition Noise Interference

Antennas

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 LTD HD 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.

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 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.

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.

CB Antenna

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 when 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.

A standard antenna connector is provided on the transceiver for easy connection.

The CB/PA button should be in the CB position.

Operation

Turning On Setting Channel

Selector

Turning On

Make sure the power cord,antenna and microphone are connected to their proper connectors before starting.

Setting Channel Selector

Rotate the On/Off Volume knob clockwise to a normal listening level.
