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 (15 on
the rear panel. Make sure, that all plugs are firmly tightened and properly sol-
dered. Insufficient connections can damage the radio and will reduce the range
of operation.
The antenna should be configured with the radio, otherwise a part of the transmit
power will be reflected at the antenna and will not be radiated. This reduces the
range of operation. The configuration of an antenna to a radio, is performed by a
length adjustment of the antenna’s radial for a minimal 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.
Installation in the car
When you want to install the radio in your vehicle, use either the included under-
dash or radio compartment mounting kit. Always mount the transceiver in a location
where the buttons are easily accessible. Other important points to consider for a
correct mounting position are:
> roadworthiness,
> good access to the controls of the car,
> sufficient air circulation to prevent overheating of the radio in transmit mode.
Please consider your point of view onto the display while driving. Starting
xtensive solar irradiation can also affect the readability of the diXsplay. So it is
recommended to check the best position before the final installation.
Microphone
Included in the scope of delivery is the VOX microphone DM-6006. The VOX fea-
ture offers voice operated signal transmission which is useful in the application of
communication while driving a vehicle. It allows to switch between the operation
modes VOX and PTT which stands for push-to-talk.
The DM-6006 is equipped with the following elements:

VOX-Sensitivity
The required signal strength to trigger automatic transmission is set with VOX
sensitivity.
There are four levels available.
A
long push
of the key [
] ( 17 ) activates the set mode for VOX-Sensitivity. It
is confirmed by a long tone and blinking of the LED.
A
short push
of the key selects the next level. The four different levels are distin-
guished by the number of tones that are emitted. For the greatest sensitivity select
the level 1 (one tone is emitted).
A confirmation of the setting is not required.
VOX-Delay
The gap between the signal end and the end of the transmission can be
changed with the setting VOX-Delay. There are four levels available.
A
long push
of the key [
] ( 18 ) activates the set mode for VOX-Delay. It is
confirmed by a long tone and blinking of the LED.
A
short push
of the key selects the next level. The four different levels are distin-
guished by the number of tones that are emitted. For the greatest sensitivity select
the level 1 (one tone is emitted).
A confirmation of the setting is not required.
Plug the microphone plug (20) into the 6pin socket (15), located on the front
panel, and thighten the union nut. Pay attention to proper placement. No trans-
mission nor reception is possible without the microphone.
Power source
Before connecting the unit to a suitable power source via the fused DC power
cable, the device must be switched off by turning the volume control (1) [
VOL
]
counterclockwise to the very end, beyond the threshold, until you hear a click.
Then, connect the two naked leads at the end of the cable with the supply vol-
tage of the vehicle’s battery. The unit is designed to operate with 12 V or 24 V
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 the + PLUS of the vehicle’s battery.
After proper connection of the aerial and the power source, radio operation can
be started.
