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. Installation Mounting and Connection Note The transceiver is held in the universal mounting bracket by four 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. 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. 3 Connect the antenna cable plug to the receptacle marked "ANT" on the back of the unit. 2 Drill the holes and secure the bracket. continued 2 3 148 NW ST manual 3.3 6/15/99 3:12 PM Page 4 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 t wo) to the engine block (or chassis).A negatively grounded vehicle has its negative lead grounded to the chassis. Installation 6 Plug power cable into back of unit mar ked "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. 7 4 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. 5 8 Attach the 4-pin microphone cable to receptacle on front of unit and Install unit in bracket securely. 5 4 148 NW ST manual 3.3 6/15/99 3:12 PM Page 6 Antennas CB Antenna Note Ignition Noise Interference CB Antenna 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 148 NW ST 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. Since the maximum allowable power output of the transmitter is limited by the FCC,the antenna For optimum performance in is critical in affecting transmission distance. Only passenger cars the ideal anten- a properly matched antenna system will allow na location is on the center of maximum power output. Cobra loaded type the roof. Second choice is on the antenna models are highly recommended for center of the trunk. most installations. Consult your Cobra dealer for further details, or call 773.889.3087 and speak to Note a Cobra representative. 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 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 7 148 NW ST manual 3.3 6/15/99 3:12 PM Page 8 Operation Turning On Turning On Make sure the power cord, antenna and microphone are connected to their proper connectors before starting. Operation Setting Channel Selector Setting Channel Selector 1 1 The CB/PA button should be in the CB position. Select one of forty channels and adjust volume. The selected channel is indicated by the LED readout directly above the channel selector knob 2 Rotate the On/Off Volume knob a normal listening level. clockwise to 8 9 148 NW ST manual 3.3 6/15/99 3:12 PM Page 10 Operation To Receive To Receive The SoundTracker TM System While previous systems only "blanket out" or limit noise in higher sound frequencies, the revolutionary new SoundTrackerTM System actually reduces noise while leaving the signal intact in the reception mode. In the transmission mode, it actually strengthens the signal,providing you with a significant reduction in noise on reception and transmission. Operation Note SoundTrackerTM gives you clearer, cleaner reception to improve CB communications while on the air. 1 Rotate the On/Off Volume knob clockwise the green RT/TX LED will be illuminated. Sound clarity is measured by the ratio of the signal level to the noise level. The higher the signal-to-noise ratio, the better the sound. How SoundTracker TM Works On Reception - "Cuts noise coming in" With a normal CB, distant signals fall below the squelch level and are unintelligible. With a SoundTrackerTM CB, the noise level is cut up to 90%,which increases the signal-to-noise ratio and dramatically improves signal clarity. This also allows you to significantly reduce the squelch level,which greatly expands your listening range. On Transmission - "Strengthens signals going out" A SoundTrackerTM CB strengthens the transmit signal by more effectively using the available RF power output of the CB. The result is improved transmission signal clarity and an expanded transmission range. S-Meter S-Meter Swings proportionately to strength of incoming signal when receiving. 1 The S/RF-SWR-CAL switch must be in the S/RF position to read the meter. 10 11 148 NW ST manual 3.3 6/15/99 3:12 PM Page 12 Operation Activating SoundTrackerTM Activating SoundTrackerTM NB-ANL/ANL/OFF (Noise Blanker/Automatic Noise Limiter) Switch Operation NB-ANL/ANL/ OFF (Noise Blanker / Automatic Noise Limiter) Switch Note The RF Noise Blanker is very effective in reducing repetitive noises such as ignition interference. The Automatic Noise Limiter helps reduce noise created by the vehicle's electronics. 1 Push and release the ST button. Red LED is illuminated when SoundTrackerTM is turned on. 1 When switched to ANL the Automatic Noise Limiter is activated. This helps reduce noise created by the vehicle's electronics. When switched to NB/ANL position the RF Noise Blanker is also activated, providing increased noise filtration. When switched to OFF position all noise filtration will be turned off.

Gate set to Desired Squelch Setting (DSS) 3 1 Full clockwise rotation closes the gate allowing only very strong signals to enter. To achieve the Desired Squelch Setting (DSS), turn the Squelch control counterclockwise until you hear noise. Now turn the control clockwise just until the noise stops. This is the DSS setting. Gate open 2 Full counterclockwise rotation opens the "gate" allowing all signals in. 16 17 148 NW ST manual 3.3 6/15/99 3:12 PM Page 18 Operation Calibrate For SWR (Standing Wave Ratio) Note 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. Operation Calibrate for SWR (Standing Wave Ratio) 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). 4 1 Select channel 20. While holding mic button adjust the SWR CAL knob so the meter needle swings to the CAL w mark on the meter (located on the right). If optimum signal is not achieved (less than 3) a slight adjustment to the length of the antenna must Note be made. Recalibrate. The reading will be slightly highRepeat the same steps on Channel 1 and 40. er on Channels 1 and 40 compared to Channel 20. 5 6 2 Switch to the CAL position. Continue holding the mic button and turn the Note SWR CAL knob to the SWR position for SWR When switched to SWR position measurement. the meter needle should ideally be as far to the left as possible. Anything over 3 is not acceptable. A slight antenna height adjustment (higher or lower) may be required.

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.) 1 2 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 3 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. 4 What's Included with Your 148 NW ST 5 1. 2. 3. 4. 5.
