REPARATION
:
To connect the amplifier to coaxial cables, you must first fit them
with F connectors 75
Ohm. F connectors are available in various
designs, so that direct connection of different cable diameters is
possible. The following describes how to connect the amplifier and
coaxial cables:

ASK
1.
Plug the F connector into both the input and output connection
sockets of the amplifier and screw the outer ring of the F
connector tight.
2.
Make sure the coaxial cables are laid with a sufficient bending
radius.
3.
Connect the device to the mains voltage by inserting the mains
plug.

The device is now ready for operation. The power indicator [3] (see
picture left) lights up.
Configuration and start-up
The default configuration for the amplifier is as follows:
The jumpers for activating the interstage attenuation and the
interstage slope are set to 0 dB
First configure the amplifier for the transmission of forward signals:
T
ASK
1.
Remove the housing cover by loosening the cover
screw.
2.
The HV 433-85 Vario amplifier has an attenuator (0...15 dB) [1]
and a tilt equaliser (0...15 dB) [2] in the input (see left). They
can be used to set the desired attenuation and equalisation by
inserting the appropriate pad.
