Installation
Always mount the transceiver where the switches are easy accessible. Important points of
view for the correct mounting position are:
☛
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 LED-display is only good readable from a certain angle. An
intensive solar radiation can also affect the readability of the display. So it is recommended
to check the best position before the final installation. The unit can easily be fixed onto dif-
ferent positions in the car by using the enclosed mounting bracket.
Microphone DM-106S or DM-106VOX
Plug the microphone into the 6 pin socket ( 19 ) 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 assignment
PIN 2 Speaker
PIN 3 PTT
PIN 4 UP/DOWN
PIN 5 Ground
PIN 6 +12 Volt
The MC-8 is available with 2 different microphones, i.e. either the standard microphone
DM-106S equipped with channel selection and signal tone or the VOX microphone
DM-106VOX with channel selection and VOX function. The VOX function is a on/off switch-
able voice activated control of the transmitter. When the VOX function is switched on the
transmitter will be activated automatically by speaking in the microphone without pressing the
push to talk key at the microphone anymore. The delay time ( on air time while speaking
breaks ) and sensitivity ( adjustment to your personal voice volume ) of the VOX function is
individually adjustable. While transmitting the TX control LED at the microphone lights up.
Power source
Before connecting the power source to the fused DC power cable ( 23 ) [ DC 13.2V ] the device
must be switched OFF by turning the volume control ( 17 ) [ VOL / OFF ] anticlockwise as far
as the stop and hearing a switching sound. The transceiver is designed to operate from a power
source of 13.8 volts DC, employing negative ground electrical system. For base-station opera-
tion use a suitable power supply ( 13,2 V / 2,0 A, e. g. TEAM LabNT ). The power supply should
be designed for operation with a transceiver, otherwise interference from the mains may occur.
Lay the cable as far as possible away from aggregates which can cause interference.
Watch for the correct polarity of the DC power cable.
BLACK connect to - MINUS / ground of the car battery.
RED
connect to 12 volts + PLUS of the car battery.
After microphone, aerial and power source have been correctly connected, radio operation
can be undertaken.

Installation of a CB-antenna
The antenna is one of the most important parts of the equipment. The type of antenna and
its location has a great effect on the range of operation. Please consider the following crite-
ria for selecting the best location and installation of your antenna:
❐
Make sure that the antenna is designed for radio operation on 27 MHz.
❐
The location of the antenna should be as high as possible without any obstacles nearby.
❐
The aerial cable should not be damaged and the plugs should be satisfactory connected.
❐
Make sure that the antenna cable is not bent too strong.
❐
The bigger the mechanical size of the antenna, the higher the range of operation.
When you install a mobile antenna please note the following advice:
❐
The antenna should be fixed in the centre of a bigger part of the coachwork.
❐
The mobile antenna coil should have the closest possible contact with a conducting metal-
lic surface of the bodywork of the car.
There are also some other possibilities to fix the antenna onto the car without the necessity
to drill a hole into the bodywork of your car, for example mounting the antenna onto the gut-
ter, mounting the antenna onto a holder on the cover of the boot or using an antenna with a
magnetic foot or using a windscreen antenna.
For base-station operation we recommend a stationary antenna on the roof, for example the
TEAM ECO 050 or ECO 200.
❐
Please don’t mount the CB antenna nearby a radio or TV antenna to prevent interference
of radio or TV reception.
❐
Keep an eye on power lines running along nearby when mounting the antenna on the roof.
" DANGER "
❐
The base-station antenna has to be connected via a lightning arrester.
❐
All connected cables including the antenna cable must not exceed a length of 3 m.
Aerial Connection
Before pressing the transmit key, a suitable aerial must be connected. The PL259 plug of the
aerial cable ( coax ) is connected to the SO239 socket ( 22 ) [ANT] on the rear panel. Make
sure, that all plugs are firmly tightened and properly soldered. Unsatisfactory connections can
damage the radio and will reduce the range of operation.
The antenna should be matched with the radio, otherwise a part of the transmit power will be
reflected at the antenna and will not be radiated. This causes also a drop in the range of oper-
ation. The matching can be carried out by a length adjustment of the antenna radial for a min-
imal SWR ratio which can be measured by a SWR meter ( e. g. TEAM SWR 1180P ). After
the measurement the SWR meter should be removed from the antenna line.
