and
3,
please
read
and
observe
the
following:
Power
Supply
Do
not
use
this
unit
on
the
same
power
circuit
with
any
device
that
will
generate
line
noise
(such
as
an
electric
motor
or
variable
lighting
system).
Before
connecting
this
unit
to
other
devices,
turn
off
the
power
to
all
units.
This
will
help
prevent
malfunctions
and/or
damage
to
speakers
or
other
devices.
Placement
Using
the
unit
near
power
amplifiers
(or
other
equipment
containing
large
power
transformers)
may
induce
hum.
To
alleviate
the
problem,
change
the
orientation
of
this
unit;
or
move
it
farther
away
from
the
source
of
inter-
ference.
This
device
may
interfere
with
radio
and
television
reception.
Do
not
use
this
device
in
the
vicinity
of
such
receivers.
Do
not
expose
the
unit
to
direct
sunlight,
place
it
near
devices
that
radiate
heat,
leave
it
inside
an
enclosed
vehicle,
or
otherwise
subject
it
to
temperature
extremes.
Excessive
heat
can
deform
or
discolor
the
unit.
To
avoid
possible
breakdown,
do
not
use
the
unit
in
a
wet
area,
such
as
an
area
exposed
to
rain
or
other
moisture.
Maintenance
For
everyday
cleaning
wipe
the
unit
with
a
soft,
dry
cloth
or
one
that
has
been
slightly
dampened
with
water.
To
remove
stubborn
dirt,
use
a
cloth
impregnated
with
a
mild,
non-abrasive
detergent.
Afterwards,
be
sure
to
wipe
the
unit
thoroughly
with
a
soft,
dry
cloth.
Never
use
benzine,
thinners,
alcohol
or
solvents
of
any
kind,
to
avoid
the
possibility
of
discoloration
and/or
deformation.
Additional
Precautions
(
€
This
product
complies
with
the
requirements
of
European
Directives
EMC
89/336/EEC
and
LVD
73/23/EEC.
Unfortunately,
it
may
be
impossible
to
restore
the
contents
of
data
that
was
stored
on
a
floppy
disk
once
it
has
been
lost.
Roland
Corporation
assumes
no
liability
concerning
such
loss
of
data.
Use
a
reasonable
amount
of
care
when
using
the
unit's
buttons,
sliders,
or
other
controls;
and
when
using
its
jacks
and
connectors.
Rough
handling
can
lead
to
malfunctions.
When
connecting
/
disconnecting
all
cables,
grasp
the
connector
itself—never
pull
on
the
cable.
This
way
you
will
avoid
causing
shorts,
or
damage
to
the
cable's
internal
elements.
A
small
amount
of
heat
will
radiate
from
the
unit
during
normal
operation.
To
avoid
disturbing
your
neighbors,
try
to
keep
the
unit’s
volume
at
reasonable
levels.
You
may
prefer
to
use
headphones,
so
you
do
not
need
to
be
concerned
about
those
around
you
(especially
when
it
is
late
at
night).
When
you
need
to
transport
the
unit,
pack
it
in
shock-
absorbent
material.
Transporting
the
unit
without
doing
so
can
cause
it
to
become
scratched
or
damaged,
and
could
lead
to
malfunction.
