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 ca-

bles:

ASK

Plug the F connectors into the corresponding sockets of the

amplifier (input [6] and output [5]) and screw the outer ring of

the F connector tight.

Make sure the coaxial cables are laid with a sufficient bending

radius.

Connect the device to the mains voltage by inserting the mains

plug.

ESULT

The device is now ready for operation. The power indicator lights

up.

The device is delivered with all attenuators in the forward and return

paths screwed in. To operate the amplifier, they must be set accord-

ing to the requirements of the cable network.



The jumper for setting the interstage slope is set to

0 dB

NOTE

an attenuation range greater than 15 dB, but the speci-fied

characteristics can only be provided up to an attenuation

value of 15 dB.

ATTENTION

attenuators screwed in to avoid a possible network

malfunction or the destruction of the device during

operation. This setting must not be changed in networks

that do not use a return path!

All attenuators in the forward and return paths have
