INSTALLATION INSTRUCTIONS Your new MCB-100 WXD is designed to be installed in-dash, under/over the dash or anywhere INSIDE your vehicle. Safety and convenience should be your primary considerations in deciding exactly where to locate your CB radio. CAUTION: Be sure the unit is located where it will not interfere with the driver or impair access to any controls necessary for the safe driving of the vehicle.
The in-dash CB unit requires a rear support. Use the provided metal mounting strap (fig. 4) or a rear support bushing (not included). DO NOT remove the factory pre-installed screws from the sides of the radio (fig. 1). They lock the CB unit securely into the mounting collar. fig. 1 1. Before inserting the mounting collar into the dash, push the side tabs inward with a slight pressure (fig. 2a). Insert the mounting collar into the dashboard opening (fig. 2b).
2. Connect power plug, external speaker, and mobile antenna cable and slide the CB unit into the mounting collar. The side tabs will expand and lock the CB unit into place. Secure rear support with provided metal mounting strap (fig. 4) or use a rear support bushing (not included). fig. 4 3. Install the front faceplate trim ring around the face of the CB unit. Insert the faceplate trim ring tabs into the grooves on the bottom of the CB unit.
2. Use the provided tools for removal of the CB. Place one on each side of the unit with the notches and part numbers on the tools facing toward the CB. Insert the tools and push in until they click and lock, then gently but firmly pull the CB unit forward (fig. 5). fig. 5 Under/Over Dash Installation Under/over dash installation requires the following provided hardware: U-shaped mounting bracket, locking washers, retention knobs, microphone hanger bracket and self-tapping screws. 1.
3. Determine the mounting location of the radio. 4. Use the U-shaped mounting bracket as a template for marking the location of the screw holes. CAUTION: Extreme care should be exercised when drilling up into the dash to avoid damage to in-dash electronic ignition wiring, cruise control, instruments, air lines or accessory wiring. 5. Drill the necessary holes and secure the U-shaped mounting bracket with self-tapping screws (fig. 8). 6. Position the CB unit between the mounting bracket arms (fig.
DC Power Supply Connection The MCB-100 WXD is designed for 12V DC operation in vehicles with negative (-) or positive (+) ground electrical systems. NOTE: Check your vehicle's ground requirements before you begin the radio installation. Trace the battery cable (attached to the vehicle's frame) to the battery terminal post. If the battery terminal post is marked with a minus (-) sign, it is a negative ground system. If the battery terminal post is marked with a plus (+) sign, it is a positive ground system.
ignition switch, such as a spare accessory terminal in your vehicle's fuse box. 3. Connect the orange (Batt +) Negative Ground System RED ORANGE BLACK (GROUND) wire to your vehicle's battery positive (+) terminal or to a point in the vehicle's fuse box that provides a continuous (BATT) (GROUND) source of 12 Volts even when the ignition is turned off. This connection provides last channel memory feature. Positive Ground System Connection 1.
MOBILE ANTENNA INFORMATION Your Maxon MCB-100 WXD requires a vehicle mount CB/weather antenna for operation. An antenna is not included with your MCB-100 WXD because of varying vehicle applications, individual needs, and owner cost preferences. You may use any standard 50 Ohm vehicle mount CB/weather antenna system with a PL-259 connector. Maxon antenna model WTA-4WP may be obtained from your local Maxon CB distributor/retailer.
Antenna Tuning/SWR Meter Operation Refer to the antenna manufacturer's installation manual for the recommended installation procedure and tuning specifications. Most antennas are factory tuned, however the radio's performance can usually be improved by slightly lengthening or shortening the antenna mast. Optimum CB performance is obtained by tuning your antenna system to the actual frequency of the RF signal transmitted. Refer to the Standing Wave Ratio chart (following) to interpret the SWR meter readings.
Prolonged antenna exposure to the elements (salt spray, humidity, corrosion, etc.) or vehicle vibration can cause degradation in performance. This may be indicated by a rise in the SWR meter's normal reading. Check the antenna's condition and the coaxial cable, RF electrical connections, etc. if a problem is indicated.
Standing Wave Ratio Chart The ideal SWR reading is a 1:1 ratio, or a meter reading of 1 on the SWR meter's top scale (this is obtainable mostly under radio laboratory test conditions). A 1.5:1 to 2:1 SWR ratio is excellent for most mobile CB antenna applications. Antenna installations in-thefield will probably show higher SWR meter readings. SWR RATIOS PERFORMANCE RATING DESCRIPTION 1:1 to 1.5:1 Superior Perfect match between the antenna and cable length to the CB radio transmitter's RF output power.
OPERATING INSTRUCTIONS Having properly installed and wired your new CB and connected the antenna, you are now ready to adjust your radio for optimum reception and voice transmission. For proper operation, the radio's microphone must be connected to the unit. Insert the microphone plug into the microphone jack (MIC). Push inward and tighten the plug's locking nut.
NOTE: When the squelch is set properly, the speaker will remain quiet until a signal is received. In order to receive weak signals, do not set the squelch too high. 4. Adjust the RF gain control to the desired level. In congested urban areas where reception interference is the greatest, reduce the RF gain. In rural or open country, increase the RF gain to improve the receiving sensitivity of incoming signals. To Transmit/To Receive Press and hold the push-to-talk bar.
Using The Weather Receiver There are several special radio frequencies used by the National Weather Service throughout the United States to provide continuous reports of the local weather conditions and forecasts. Taped weather messages are repeated every four to six minutes on a 24-hour basis, and are routinely revised every one to three hours, or more frequently if needed. During severe weather, the routine weather broadcasts will be interrupted with weather warning messages.
to the NOAA Weather Radio Frequency card to locate the proper weather channel for your current geographic location. The WX LED will glow green when the weather receiver is active. Re-adjust the volume if necessary. To resume normal CB operation, simply turn the CB/WX selector to the CB position.
RADIO COMMUNICATION CODES Citizens Band Radio operators have universally adopted the "10" Code for standard questions and answers. It enables them to communicate faster, easier and more understandably in noisy surroundings. When using the code 10-1, you would say "Ten one" not "One zero one". The following are some of the most common codes and their descriptions.
