Installation
Installation
Before installing the main unit in the vehicle, check and select the most convenient location, in order
that the radio will be easy to reach and comfortable to operate, without obstructing any of the vehi-
cles controls. Use the supplied bracket and hardware to install the radio. The car mounting bracket
can be installed over or below the radio and the radio may be inclined as desired(whether under
dashboard or truck cabin roof installation).
Installation of the Main Unit
Before connecting the radio to the vehicles electric system, make sure that radio is switched off,
with the OFF/VOLUME (6) knob completely turned counter clockwise at OFF position. The DC
power cable (13) of the radio is complete with a fuse holder with fuse located on the red positive (+)
wire. Connect the DC power cable to the vehicles electric system, with special attention to correct
polarity. Connect the red wire to the positive (+) pole and the black wire to the negative (-) pole of
the vehicles electric system. Make sure that the wires and terminals are firmly and stably connect-
ed, in order to prevent cables from disconnecting or causing short circuits.
Installation of the Antenna
A specific 27MHz CB antenna must be used. Please make sure to carefully install the antenna
mount on the vehicle with a good connection to ground. Before connecting the antenna to the radio,
it is necessary to check the correct operation of the antenna with low standing wave ratio (S.W.R.),
using an SWR meter. If not, the transmitter circuit of the radio could be damaged. The antenna
should be installed on the highest part of the vehicle, free from obstacles and as far away as pos-
sible from any source of electric or electromagnetic noise. The RF antenna coaxial cable must not
be damaged or pressed on its way between antenna and the radio. The correct operation of the
antenna and the low standing wave ratio (S.W.R.) must be checked periodically. Connect the RF
antenna coaxial cable to the antenna connector (12), located on the rear side of the radio.
Checking Operation of the Radio
Once the radio has been connected to the vehicles electric system and to the antenna, the correct
operation of the system may be checked. Please proceed as follows :
1) Check that the power cable is correctly connected.
2) Check that the RF antenna coaxial cable is correctly connected.
3) Connect the microphone to the connector (1), located on the front side of the radio.
4) Rotate the SQUELCH (4) knob counter clockwise.
5) Turn the radio on using the ON/OFF/VOL (6) knob and adjust the volume to the desired level.
6) Select the desired channel, using the channel selector buttons (2 and 3, or 16 and 18 on mic).
7) Rotate the SQUELCH (4) knob clockwise, to cut the background noise.
8) Press the PTT (15) key to transmit and release it to receive.
