> no interference of the roadworthiness,
> good access to the controls of the car,
> sufficient air circulation to prevent overheating of the radio in transmit mode.
Please consider that the readability of the LC display (6) depends on the angle of view. Also,
an intensive solar radiation affects the readability of the display. Please check the best posi-
tion before the final installation.
4) Microphone DM-106S
Plug the microphone (1) into the 6-pin socket (11), located on the front panel. Pay attention
to proper placement. No transmission nor reception 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 selector and signal tone
keys, is included with the MX-8. This microphone offers 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 (10) [OFF/VOL] counterclockwise
to the very end.
Then, connect the two naked leads at the 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. Pay attention to 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.
The last settings will remain stored, after the unit and the car are turned off.
For base-station operation, use a suitable power supply (13.2 V / 2.5 A, e.g. TEAM LabNT
series). The power supply should be designed for operation with a transceiver, otherwise
interference from the mains or over-voltage may occur.
After proper connection of the microphone, the aerial and power source, radio operation can
be started.

Operation of the TEAM MX-8
1) Switching on [OFF/VOL]
Before turning the radio on, set the squelch control (9) [ASQ / SQ] to SQ, to the lowest level by
turning the switch counterclockwise to the left, shortly before turning the ASQ on. The device is
switched on by turning the volume control (10) [OFF/VOL] clockwise. The LC display (6) is illu-
minated and the symbols are visible. Adjust the receiver sound with the volume control to the
desired level.
All settings are stored after the unit is switched off, as long as the power supply is not disrupted.
2) Squelch [ASQ/SQ]
The strong background noise, which occurs always on free channels, can be suppressed by
the squelch function. By turning the squelch control (9) [ASQ / SQ] slowly clockwise you will
find a point where the noise disappears. The squelch control should only be turned up far
enough to stop the constant, static noise. Turning the control further clockwise, will increas-
ingly suppress stronger interfering signals as well as weak stations.
The automatic squelch ASQ is activated by turning the squelch control counterclockwise until
the control clicks. In this position the manual SQ-squelch function is switched off and the
squelch threshold is set to default.
3) Channel selection [p] [q]
All channels can be selected by pushing the channel selector keys (2) [p] and (3) [q] at the
microphone or by turning the rotary channel selector (8) [Channel], located on the front
panel. The channel number is displayed in the center of the LCD (6). The frequency is shown
in the lower left corner.
No channel selection is possible while the radio is in TX mode. The channels are selected in
a consecutive order.
For communication with a partner CB station, both transceivers must be adjusted to the same
channel and the same modulation type.
4) Confirmation Tone [Mode]
In reception mode, all key entries - except for On/Off (10) [OFF/VOL], PTT (4) [PTT], call tone
(5) [SIGNAL] and channel selection (8) [CHANNEL] - will be confirmed with a short beep
tone. To turn on/off the confirmation tone, press the mode key (7) [MODE] for about 2 to 3
seconds, until a second short receipt tone is audible.
5) LCD background illumination [DW/B]
To switch the LCD background light between orange and blue,hold the background-light key
(12) [DW/B] for approximately 2 seconds.
