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 inst allation. 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 ( 12 ) on the front p anel. Note it will only go in
one way round. No transmission and receiving is possible without the microphone.
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 st andard microphone DM-106S, which is equipped with channel selection and signal
tone, is included with the MX-8. This microphone is the best selection for the MX-8.
5) Power source
Before connecting the unit to a suitable power source via the fused DC power cable (16), the
device must be switched off by turning the volume control ( 11 ) [ Vol / Off ] anticlockwise as
far as the stop and hearing a switching sound.
Then, connect the two naked leads at the end of the cable with the supply volt
car/lorry battery. The unit is designed to operate with 12 volt
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.

For base-station operation use a suit able power supply ( 13.2 V / 2.5 A, e. g. TEAM LabNT
series ). The power supply should be designed for operation with a transceiver
interference from the mains or over-volt age may occur.
After proper connection of the microphone, the aerial and power source, radio operation can

1) Switching on [ Vol / Off ]
Before switching the unit set the squelch control ( 10 ) [ SQ / Asq ] to the counterclockwise stop
but without activating the internal switch. The device is switched on by turning the volume con-
trol ( 11 ) [ 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 disruption of the sup-
ply source the unit works on channel number 9 in FM mode and the LCD back-light is illuminat-
ed 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 memorized after the
unit is switched off, as long as the power supply is not disrupted.
2) Scrolling Text
The pin
The scrolling text in the display informs about the selected norm - operation mode (AM / FM),
number of channels, frequency ranges and tx powers - and the currency ( 12 / 24 V ) that is
present.
These information are displayed for appr . 50 sec. when the radio get s turned on and are
repeated every minute. In transmission and reception mode, the scrolling text is aborted and
starts again after one minute after the signal ends.
There is no scrolling text available when the squelch is open, see point 3) Squelch [ SQ / Asq ].
3) 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 ( 10 ) [ 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 st ations.
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 of
the squelch threshold is set to default.
4) Channel selection [
All channels can be selected by pushing the channel selector keys ( 2 ) [
at the microphone, or by turning the rot a ry channel selector ( 9 ) [ Channel ] on the front panel
to the desired channel. The channel will be displayed on the LCD ( 6 ) with big digit s and the
frequency with small digit s. No channel selection is possible while the radio is in
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 p artner CB st ation, both trans-
ceivers must be adjusted to the same channel and the same modulation type.
5) Receipt Tone selection Hi / Lo [ Mode ]
The receipt tone selection is only available in the radio version MX-8 c and the norm 4000.
To toogle between the receipt tone high and low , press the receipt tone key ( 7 ) [ Mode ].
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 receipt tone key
( 7 ) [ Mode ] the receiving tone is changing to a bright sound in the loudspeaker. This is indi-
cated in the LCD window by the symbol " HI".
