Troubleshooting
Before
concluding
that the
amplrfier
is
defective,
ensure
that
all
connections
and
operating
procedures
conform to
the
instruc-
tions of this
manual.
Possible trouble
sources:
-
Check
cabling
-
ls the SEPARATED
switch
(rear
panel) pressed
or
released?
-
ls the speaker
selector
in
the
correct
position?
-
Has
the correct
source been
selected?
-
Gain
too
low:
is
the
-20dB
button
pressed?
-
Sound
distorted:
is
the
-20
dB button
pressed
and the
amplifi-
er
set
for very
high output
volume?
-
No output
f rom PHONO
input:
is the PHONO switch
[10]
in M C
position
or the
corresponding
capacitance?
-
lf the amplif
ier can
no longer
be operated,
disconnect
amplifi-
er
from AC supply
and
reconnect
it to force
reinitialization
of
microprocessor.
