3.1 Where and how to mount your mobile CB radio
① You should choose the most appropriate setting from a simple and
practical point of view.
② Your CB radio should not interfere with the driver or the passengers.
③ Remember to provide for the passing and protection of different
wires (e.g, power ,antenna, accessory cabling) so that they do not
interfere in any way with the driving of the vehicle.
④To install your equipment, use the cradle ❶ and the self-tapping
screws ❷ provided (drilling diameter 3.2mm). Take care not to
damage the vehicle's electrical system while drilling the dash
board.
⑤Do not forget to insert the rubber joints ❸between the CB and
it's support as these have a shock-absorbing effect which permits
gentle orientation and tightening of the set.
⑥Choose where to place the microphone support and remember
that the microphone cord must stretch to the driver without
interfering with the controls of the vehicle.

Choosing your antenna
• For CB radios, the longer and matched antenna is the better
results.
Mobile antenna
• Must be fixed to the vehicle where there is a maximum of metallic
surface (ground plane), away from windscreen mountings.
• If you already have a radio-telephone antenna installed, the CB
antenna should be higher than this.
• For an antenna which must be fixed by drilling, you will need a
good contact between the antenna and the ground plane.
• To obtain this, you should lightly scratch the surface where the
screw and tightening star are be placed.
• Connect the antenna .
Fixed antenna
• A fixed antenna should be installed in as clear space as possible,
If it is fixed to a mast, it will perhaps be necessary to stay it,
according to the laws in force (you should seek professional
advice).
Connecting an external antenna
3.2 Antenna installation
WARNING!
The antenna used for this radio must be installed at least 25
inches (63 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.
SECTION 3
INSTALLATION
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.
• Tune your antenna using a Standing-Wave Ratio (SWR) meter: set
the radio to channel 20, and adjust the antenna until the SWR is as
close as 1:1 as possible.
3.3 Power connection
Your LEGEND II PLUS is protected against an inversion of polarities. Your
equipment must be supplied with a continued current of 12 volts .
① Check that the battery is of 12 volts.
② Locate the positive and negative terminals of the battery (⊕ is red
and ⊖ is black).
③ It is necessary to connect your CB to a permanent ⊕and ⊖.
④Connect the red wire ⊕ to the positive terminal of the battery and
the black ⊖ wire to the negative terminal of the battery.
⑤Connect the power cable to your CB radio.
INSTALLATION
CAUTION!
NEVER Make sure the SWR is less than 2:1 before using the radio.
The SWR higher than 2:1 can damage the transmitter.
* Your dealer can help you select the antenna that is best for your needs. Consult
the specifications in the back of this manual for detailed transmitter and antenna
information.
WARNING!
NEVER replace the original fuse (3 Amp.) by one of a different value.

3.4 Basic operations before using your set for the first time
* Without transmitting and without using the [PTT] switch on the
microphone
① Connect this microphone.
② Check the antenna connections.
③ Turn the volume knob clockwise to power ON the device.
④ Adjust the volume to a comfortable level.
⑤ Go to channel 20 using either the [UP]/[DN] key on the microphone.
3.5 Adjustment of SWR (Standing Wave Ratio)
INSTALLATION
WARNING!
This must be carried out when you use your CB radio for the first time
(and whenever you re-position your antenna). The adjustment must
be carried out in an obstacle-free area.
* Adjustment with an external SWR meter.
To connect the SWR meter:
• Connect the SWR meter between the CB radio and the antenna
as close as possible to the CB.
To adjust the SWR meter:
• Set the CB to channel 20 in FM.
• The reading on the Meter should be as near as possible to 1. If
this is not the case ,re-adjust your antenna to obtain a reading
as close as possible to 1. (The SWR reading between 1 and 1.8 is
acceptable).
• It will be necessary to re-calibrate the SWR meter after each
adjustment of the antenna.

4.3 ASQ (Automatic Squelch Control)/ SQL
Suppresses undesirable background noises when there is no
communication. Squelch does not affect neither sound nor
transmission power, but allows a considerable improvement in
listening comfort.
4.2 Volume control
Increase the volume
Turn the volume knob clockwise until the
display comes on to on the radio.
Turn the SQL switch knob
counterclockwise to ASQ position.
Turn the SQL switch knob clockwise to
increase the squelch level to filter out
weaker signals and background noise.
Turn the volume knob clockwise to
increase the volume.
Turn the volume knob counterclockwise
until the display off to off the radio.
Turn the volume knob counterclockwise
to decrease the volume.
