►Make sure the radio and microphone are not in front of an airbag.
►Pick a solid surface that can support the weight of the bracket and the radio.
►Make sure there’s enough room. (You may want to put the radio in the bracket
when you’re choosing where to install the bracket.)
Once you choose the location, use the included, self-tapping screws to attach the
mounting bracket and the microphone bracket to your vehicle (you don’t have to
drill holes). Slide the radio into the bracket and use the included knobs to hold it
at the preferred angle.
Connecting an external antenna
WARNING! The antenna used for this radio must be installed at least 8 inches
(20 cm) away from all persons. The antenna must not be collocated or used with
any other antenna or transmitter.
CAUTION: Never operate your radio with no antenna or with a damaged antenna
cable. This can damage the radio
You will need to purchase an antenna to operate the radio. There are two basic
types of mobile CB antennas--full-length whips and loaded whips--with a wide
variety of mounts to suit different vehicle locations.
►Choose an antenna that matches the specifications of this radio.
►Follow the manufacturer’s installation instructions carefully.
