Uninstalling plug-in cards
After disconnecting the cable connections, lift out the
plug-in cards with the supplied plug-in card removal
tool. Place the lever between the card and the alumi-
num frame and press down. This disconnects the plug
contacts of the card from the mainboard (Fig. 11).
IMPORTANT NOTE:
Installing of plug-in cards only after disconnecting
the mains supply of the base unit!

Configuration of all plug-in cards
Detailed information about setting the individual plug-
in cards is available in the supplied operating instruc-
tions.
7
Level adjustment
The optimal output level (measured at the output of the
base device) is as follows:
•
100 dBµV for PAL channels
•
90 dBµV for QAM channels
•
96 dBµV for radio (FM) channels
To enable the setting, the level regulators of the indivi-
dual plug-in cards are set accordingly (Fig. 12).
Note:
Under no circumstances should a skewed position be
set to compensate outgoing cable attenuation by means
of different level adjustments of the plug-in cards! For
this purpose use output coupling field
U-901
(order no.
380 190) or
VZN 8
(order no. 380 191).
