> no interference of the roadworthiness,
> good access of the controls of the car,
> sufficient air circulation to prevent overheating of the radio in transmit mode.
Please take into account that the LC display ( 6 ) is only good readable from a certain angle.
An intensive solar irradiation can also affect the readability of the display. So it is recommen-
ded to check the best position before the final installation. The unit can easily be fixed onto
different positions in the car by using the enclosed mounting bracket.
4) Microphone DM-106S
Plug the microphone ( 1 ) into the 6 pin socket ( 10 ) on the front panel. Note it will only go in
one way round. No transmission and receiving is possible without the microphone. The pin
assignment of the GDCH standard microphone plug is given below:
PIN 1 Modulation
PIN 2 Loudspeaker
PIN 3 PTT
PIN 4 Up/Down
PIN 5 Ground
PIN 6 +12 Volt
Solder side view of the microphone connector or top view of the microphone plug.
The standard microphone DM-106S, which is equipped with channel selection and signal
tone, is included with the RoadCom-FS. This microphone is the best selection for the Road-
Com-FS. If you want to use instead another microphone than the supplied DM-106S, you
have to ensure that the microphone capsule remains also in released PTT key position con-
nected with the modulator input of the transceiver. Otherwise the VOX function ( voice acti-
vated control of the transmitter ) of the RoadCom-FS cannot work.
5) Power source
Before connecting the unit to a suitable power source via the enclosed fused DC power cable,
the device must be switched off by turning the volume control ( 7 ) [ Vol / Off ] anticlockwise
as far as the stop and hearing a switching sound. Now connect the power cable to the con-
nector ( 22 ) on the rear panel. To protect the transceiver against wrong polarity, the cable
plug fits only in one way into the connector ( 22 ).
Then connect the two naked leads at the other end of the cable with the supply voltage of the
car/lorry battery. The unit is designed to operate with 12 volts or 24 volts and a negative
ground electrical system. Lay the cable as far as possible away from aggregates which can
cause interference. Watch for the correct polarity during the connection.
BLACK connect to - MINUS / ground of the car battery.
RED connect to 12/24 volts + PLUS of the car/lorry battery.
If the power source is not disconnected after putting the engine off, the last settings will
remain stored, after the unit and the car are switched off.
For base-station operation use a suitable power supply ( 13.2 V / 2.5 A ). The power supply
should be designed for operation with a transceiver, otherwise interference from the mains or
over-voltage may occur.
After microphone, aerial and power source have been correctly connected, radio operation
can be undertaken.

Operation of the Conrad RoadCom-FS
1) Switching on [ Vol / Off ]
Before switching the unit set the squelch control ( 8 ) [ SQ / Asq ] to the counterclockwise
stop but without activating the internal switch. The device is switched on by turning the vol-
ume control ( 7 ) [ Vol / Off ] clockwise to the centre position. The symbols are shown at the
LC display ( 6 ) and the LCD backlight is illuminated. When being switched on after a disrup-
tion of the supply source the unit works on channel number 9 in FM mode and the LCD back-
light is illuminated in orange or blue. Adjust the receiver sound with the volume control to the
desired level.
All settings, which are made during operation of the transceiver, remain memorised after the
unit is switched off, as long as the power supply is not disrupted.
2) Squelch [ SQ / Asq ]
The strong background noise, which occurs always on free channels, can be suppressed by
the squelch function. By turning the squelch control ( 8 ) [ SQ / Asq ] slowly clockwise you
will find a point where the noise disappears. The squelch control should only be turned up far
enough to stop the background noise on an unused channel. Turning the control further clock-
wise will increasingly suppress stronger interfering signals as well as weak stations.
The automatic squelch [ Asq ] can be activated by turning the squelch control counterclock-
wise until the control clicks. In this position the normal squelch function is switched off and
the squelch threshold is set to default.
3) Confirmation tones
In reception mode all entries made by the keys, except the VOX function On/Off switch ( 13 ),
the PTT key ( 4 ) [ PTT ] and the call tone key ( 5 ) [ SIGNAL ] will be confirmed with a short
receipt tone. If you want to switch off the tones, press the channel scanning key ( 15 )
[ Scan ] for about 2 to 3 seconds, until a second, short receipt tone comes from the speaker.
Now, the unit will be silent, if any keys are pressed.
In the same way, the receipt tones can be reactivated.
4) Channel selection [ ] [ ]
All channels can be selected by pushing the channel selector keys ( 2 ) [
at the microphone, or by turning the rotary channel selector ( 9 ) [ Channel ] on the front panel
to the desired channel. The channel will be displayed on the LCD ( 6 ) with big digits and the
frequency with small digits. No channel selection is possible while the radio is in TX mode.
The channels step in a ring like system. That means you go from the highest channel num-
ber to channel 1 and vice versa. For communication with a partner CB station, both trans-
ceivers must be adjusted to the same channel and the same modulation type.
5) Audio reproduction sound selection [ Hi / Lo ]
The RoadCom-FS is equipped with an audio reproduction sound toggle key ( 18 ) [ Hi / Lo ].
When being switched on after a disruption of the supply source the receiving sound is set to
mellow, which is indicated in the LCD by the symbol "LO". By pushing the audio reproduction
sound key ( 18 ) [ Hi / Lo ] the receiving tone is changing to a bright sound in the loudspeak-
er. This is indicated in the LCD window by the symbol "HI". By pushing the sound key again,
the receiving tone is changed back to mellow, indicated by the symbol "LO".
