Nothing operates.
Check the output transformer voltage between SEC terminals: it should have 12 to 17Va.c. If
not, disconnect the transformer from the installation and measure again. If it's correct now,
it means there is a short circuit in the installation: disconnect the transformer from mains
and check the installation.
Inappropriate audio level.
Adjust the level volumes as shown on page 44. In case of feedback, reduce the audio levels
until feedback fade out.
Door open function no operates.
Disconnect the lock release from the sound module and short-circuit terminals ' ' and 'P': at
that moment the output voltage between terminals 'CV' and '~2' of the sound module
should be 12Va.c. If it's so check the lock release, its wiring and the wiring of the terminal
'P' from the sound module to the telephones. If these tests don't solve the problem, replace
the sound module.
Check that the introduced code is a valid code to activate the relay connected to the lock
release.
No telephones receive the call or acknowledgement call signal is not reproduced.
Check that the push buttons common terminal are correctly connected to the 'CP' terminal of
the sound module.
