Installation Location 2 Mounting and Connection Mounting and Connection Hold the radio with the mounting bracket in the exact desired location. If there is no inter- ference, remove the bracket and use it as a template to mark the location for the mount- ing screws.
Installation 3 continued Connect the antenna cable plug to the recep- tacle marked “ANT” on the back of the unit. 3.
Installation 4 Note Before installing the CB radio, visually check the vehicle’s battery connection to deter- mine which terminal, positive or negative, is grounded (pos- itive is the larger of the two) to the engine block (or chas- sis). A negatively grounded vehicle has its negative lead grounded to the chassis.
5 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 sup- plied. Bracket should be placed under the dash so microphone is readily accessible.
Antennas CB Antenna Since the maximum allowa ble power output of the transm itter is limited by the FCC, the antenn a is critica l in affect ing transmissi on dist ance. Only a proper ly matched antenna system will allow maxi- mum power outp ut. Cobra loaded type ante nna models are highly recomm ended for most instal- lation s.
Ignition Noise Interference Use of a mobile receiver at low signal levels is normally limited by the presence of electrical noise. The primary source of noise in automo- biles is from the alternator and ignition system. Typically, when signal level is adequate, the back- ground noise does not present a serious problem.
Press the CB/PA/WX button to change modes.

Operation Calibrate For SWR (Standing Wave Ratio) 10 Press SWR/CAL button to select CAL. 2 1 Calibrate for SWR (Standing Wave Ratio) 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.
While holding mic button adjust the SWR CAL knob so the meter swings to the CAL mark on the meter (located on the right). Operation 11 continued 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.
Rotate the On/Off Volume knob clockwise. The RX icon will be displayed. Repeat the same steps two through five on Channel 1 and 40. This will check SWR for all channels. 6 While still holding down the mic button, press and release the S/RF SWR CAL button to the SWR setting, to read the SWR reading.
The S/RF-SWR-CAL switch must be in the S/RF setting to read the meter. Operation 13 1 S-Meter S-Meter Swings proportionately to strength of incoming signal when receiving. Unit should be in CB mode. Rotate channel selector clockwide or counter-clockwise to select desired channel.
PUSH & HOLD To Transmit To Transmit 14 Caution! Be sure the antenna is properly connected to the radio before transmitting. Prolonged trans- mitting without an antenna, or a poorly matched antenna, could cause damage to the transmitter. Be sure to read the F.

Operation S/RF Meter S/RF Meter This meter swings proportionately to the RF output (outgoing signal) while transmitting. The S/RF-SWR-CAL button must be in the S/RF mode. 1 28 To achieve the Desired Squelch Setting (DSS), turn the Squelch control counterclockwise until you hear noise.
Operation 29 External Speaker External Speaker The external speaker jack is used for remote receiver monitoring. Note The external speaker should have 8-ohm impedance and be rated to handle at least 4.0 watts. When the external speak- er is plugged in, the internal speaker is automatically discon- nected.
Operation 30 PA (Public Address) PA (Public Address) Connect an external PA speaker to the PA jack on the rear panel. Press CB/WX/PA button to select PA. Note Speaker should have 8-ohm impedance and be rated to handle at least 4.0 watts. Note The speaker should be directed away from the microphone to prevent acoustic feedback.
Operation 31 Push and hold microphone button and speak in a normal voice. Your voice will now transmit on the PA speaker. Adjust PA speaker volume with the Dynamike ® control.
Home And Office Set-Up 32 Base Station Operation (From 120V AC House Current) 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 Pack rated at a minimum of 2 amps, and a properly installed base station antenna.
Temporary Mobile Set-Up 33 Temporary Mobile Set-Up Temporary Mobile Operation For temporary mobile operation you may want to purchase an optional cigarette lighter adapter from your COBRA dealer. This adapter and a magnetic mount antenna allow you to quickly “install” your transceiver for temporary use.
