of
the
PUX-020.
Special
attention
should
be

After
setting
the

switch
the

raise
the

a
swift
manner.
(3)
By
adjusting
VR1

CAUTION
1.
Never
switch
off
power
until
the
idling

adjustments
for
Class-A
operations
have
been
completed.
2.
Special
attention
should
be
paid
in
handling
the
variable
resistors
used
for
adjustments,
i.e.,
VR3
and
VR4,
and
VR5
and
VR6,
as
they
can
be
easily
mistaken
for
one
another.
lf
by
mistake,
VR5,
or
VR6
has
been
used
for
the
idling
current
adjustment
for
A-class
operations,
readjustment
must
be
carried
out
(after
confirming
that
the
radiator
of
the
power
amplifier
has
cooled
down)
for
B-class
operations,
since
the
mistake
will
cause
a
deviation
in
the
adjustment
for
B-class
operations.
On
completion
of
this,
carry
out
adjustments
for
A-class
operations
again.
