Location
Plan the location of the transceiver and microphone bracket before
starting the installation. Select a location that is convenient for
operation and does not interfere with the driver or passengers in the
vehicle. In automobiles, the transceiver is usually mounted to the
underneath of the dash panel, with the microphone bracket beside it.
Mounting Connection
The transceiver is held in the universal mounting bracket by two
thumb screws, permitting adjustment at the most convenient angle....

CB Antenna
Since the maximum allowable power output of the transmitter is
limited by the FCC, the antenna is one important factor affecting
transmission distance. Only a properly matched antenna system will
allow maximum power transfer from the 50-ohm transmission line to
the radiating element. In mobile installations (cars, trucks, boats, etc.),
an antenna system that is non-directional should be used.
Avertically polarized, quarter-wavelength whip antenna provides the
most reliable operation and...

ambient background noise is eliminated. Adjust until...

B. Rear Panel1.
ANTENNA CONNECTOR:This SO-239 connector permits
connection of the transmission line cable male connector to the
transceiver.
2.
PUBLIC ADDRESS:An external 8-ohm 4.0 watt PA speaker may be
connected to the PA Speaker Jack when this unit is used as a public
address system. The speaker should be directed away from the 
microphone to prevent acoustic feed-back. Physical separation or
isolation of the microphone and speaker must be employed when
operating the PA at high output levels.

Your COBRA CB transceiver is specifically designed for the
environment encountered in mobile installations. The use of all solid
state circuitry and its light weight result in high reliability. Should a
failure occur, however, review the following, then if necessary replace
parts only with identical parts. Do not substitute. Refer to the
schematic diagram and parts list.1.
Check connections to the source of power and make sure it is the
13.8 VDC required to operate your radio.
2.
Check the fuse in the DC...
