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.
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).
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.

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.

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.
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.

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.
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.
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).
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.
During severe weather, the routine weather broadcasts will be interrupted with weather warning messages. The MCB-100 WXD is designed to receive all seven NOAA weather frequencies as well as 3 periodic international marine weather frequencies. A frequency...

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".
