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.

29WXNWBT_MANL.qx:29WXNWBT_MANL.qx 1/7/09 4:26 PM Page 4 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. Note 6 Plug power cable into back of unit marked “Power”. Be sure to observe polarity markings.
