Installation Installation Location 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.
PAGE 3
Installation Installation 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. 6 Plug the power cord into the jack marked “Power” on the back of the unit. Be sure to observe polarity markings.
PAGE 4
Antennas Ignition Noise Interference CB Antenna 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. For models with Weather Feature (WX), a Dual Band (Center Load/Base Load) antenna is recommended.
PAGE 5
Operation Operation Turning On Turning On Setting Channel Selector Setting Channel Selector Make sure the power cord, antenna and microphone are connected to their proper connectors before starting. Note Press CB/WX to select CB, weather channels mode. 3 8 1 Rotate the On/Off Volume knob clockwise to turn unit on and adjust to a normal listening level. 2 Press the CB/WX button to change modes. Select one of forty channels and adjust volume.
PAGE 6
Operation Calibrate For SWR (Standing Wave Ratio) Operation Calibrate for SWR (Standing Wave Ratio) SWR meter calibration is required to accurately measure the SWR of the connected antenna system. Careful adjustment is critical to obtain best accuracy. PUSH & HOLD Note 3 1 Push and hold mic button. Note The reading will be slightly higher on Channels 1 and 40 compared to Channel 20. Select channel 20. 4 2 Calibration must be made in an open area (never in a garage). Vehicle doors must be closed.
PAGE 7
Operation Operation Calibrate for SWR continued Selecting A Channel Selecting A Channel Note When switched to SWR mode the meter reading 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. Repeat recalibration steps. To Receive 5 6 Release the PTT button, press and release the S/RF-SWR CAL button to the SWR position. Then press the PTT button to read the SWR reading.
PAGE 8
Operation To Transmit Operation To Transmit Setting Dynamike® Setting Dynamike® This controls the microphone sensitivity (outgoing audio level). Caution! Be sure the antenna is properly connected to the radio before transmitting. Prolonged transmitting without an antenna, or a poorly matched antenna, could cause damage to the transmitter. Be sure to read the F.C.C. Rules and Regulations included with this unit before transmitting. 1 Select desired channel.

Operation Operation Setting the Alarm continued Note Default snooze time length is 10 minutes. Note Press Dim/Escape button to return to CB standby mode. Note Default alarm length is 60 seconds and is set in 10 second increments. Setting the Count Down Timer Once alarm settings are complete, rotate Menu/Enter knob clockwise to Set Snooze and press to select. Allows testing of important radio functions. Test 1- Battery Level: Confirms that battery voltage level is between 10.8 V to 15.8 V.

Operation Operation Weather Information Weather Alert What You Should Know About Weather Note To see a full listing of NOAA Weather Radio stations and locations, please visit: weather.gov/nwr/station_listing If threatening weather is nearby, the National Weather Service may broadcast a 10 second alert tone. This tone will be heard through the CB, even if the CB/WX Control is in the CB mode or the unit is turned off.
PAGE 13
Operation Weather Alert Mode Note Press Dim/Escape button to return to CB mode. Setting Weather Alert Scan Note If an alert is detected the unit will activate WX mode on the channel with the alert. Use Menu/Enter knob to select On/Off and press to set. Operation Setting Weather Alert Mode Turns WX Alert On/Off. Default is Off. Press Menu/Enter knob to select Set WX Alert. If Weather is On, WX Alert Icon will be displayed.

Press and hold Scan/MemScan button. Memory icon will appear. Select second channel, press and hold Scan/MemScan button again until Memory icon appears. Repeat above steps to enter up to 10 channels in memory. Program Memory Channels Note The radio should be squelched before scan features are activated.
PAGE 15
Operation Scan CB Channels Operation Setting Squelch Scan CB Channels Setting Squelch To scan all 40 CB channels, the unit must be squelched. Press and release Scan/Mem Scan button once. Squelch is the “control gate” for incoming signals. Gate closed MEDIUM SIGNALS WEAK SIGNALS Scan Memory Channels Scan Memory Channels To scan memory channels, press and release Scan/Mem Scan button twice. 1 Full clockwise rotation closes the gate allowing only very strong signals to enter.

Home And Office Set-Up Base Station Operation (From 120V AC House Current) Temporary Mobile Set-Up Base Station Operation (From 120V AC House Current) To operate your transceiver from home or office you will need a 13.2 volt DC Power Supply rated at a minimum of 2 amps, and a properly installed base station antenna. Warning! Do not attempt to operate this transceiver by connecting it directly to 120V AC. 2 Plug power cable into back of unit marked “Power”. Be sure to observe polarity markings.
