– If a CA module is used, check that the plug contacts of the CA module are
tightly seated in the terminal strip on the digital module and make sure there
is a reliable contact.
– Always position modules which belong together next to each other. The
digital module must be installed to the left of the modulator module.
– When installing the digital module, make sure that it is inserted in a long
numbered groove in front of a contact strip on the board at the rear wall of
the housing.
The shorter not numbered grooves without a contact strip on the board at
the rear wall of the housing are for add-on modules only.
