receo-
tion.
This equipment
has
been
tested
and
found to
comply
with
the
limits
for
a
Class B
computing
device
in
accordance
with
the
specifications
in Subpart
J,
of
Part
15,
of
FCC
Rules. These
rules
are
designed
to
provide
reasonable
pro-
tection
against such
an
interference
in
a
residential
installa-
tion.
However,
there is no
guarantee
that
the

will
not

If
this
equipment
does
cause
interference to
radio or

reception,
which
can be
determined
by
turning
the
equipment
on
and
off,
the

is
encouraged to
try
to
correct
the
interference
by
the
following
measure:
•
Disconnect
other
devices and
their
input/output
cables
one at
time.
If
the
interference
stops,
it
is caused
by
either
the
other
device
or
its I/O
cable.
These
devices
usually
require
Roland
designated
shielded
I/O
cables.
For Roland
devices,
you
can
obtain
the
proper
shielded
cable
from
your
dealer.
For non
Roland
devices,
contact
the
manufacturer
or dealer
for
assistance.
If
your

or
more
of the
following
measures:
•
Turn the
TV
or
radio
antenna
until
the

stops.
•
Move the
equipment to
one
side
or
the
other

father

•
Plug
the
equipment
into an
outlet
that is
on
a
different

(That
is,
make
certain
the
equipment
and
the
radio
or
television set
are
on
circuits
controlled
by
different
circuit
breakers
or fuses.)
•
Consider
installing a
rooftop
television
antenna
with
coaxial
cable
lead-in
between
the
antenna
and
TV.
If necessary,
you
should
consult
your
dealer
or
an
ex-
perienced
radio/television
technician
for
additional
sugges-
tions.
