IMPORTANT NOTES
In addition to the items
listed
under Safety Precautions, on page
2,
we
request
that
you
please read and adhere
to
the following.
[Power
supply]
I
Whenever
you make
any
connections with other
devices,
always
turn off the
power
to
all
equipment
first.
This
will help
in
preventing malfunction, and damage
to
speakers.
I
Do
not force the unit to share the
same power
outlet
as
one
used
for distortion
producing
devices (such as motors, variable
lighting devices).
Be
sure
to
use a separate
power
outlet.
[Other Precautions]
9
Protect the
unit
from strong impact.
#
Never
apply strong pressure
to
the display, or
strike
it
in
any
way,
#
A
certain small
amount
of heat
will
be
radiated
from
the
unit,
and
thus should not
be considered abnormal.
[Placement]
'
Before using the unit
in
a foreign country, check
first
with your
local
Roland Service
Station.
I
Placing
the unit near
power
amplifiers or other
equipment
containing
large
transformers
may
induce
hum.
'
Should
the unit
be operated nearby
television or radio
receivers,
TV
pictures
may show
signs
of
interference,
and
static
might be
heard
on
radios. In
such
cases,
move
the unit
out of proximity with such
devices.
i
Avoid
placing the unit
where
it
may
be subject
to direct
sunlight,
or
where
near devices
that
may
emanate
heat.
Avoid
confining
it
within a
tightly
closed car or other such
places.
Otherwise, the unit
may
become deformed
or discolored.

[Maintenance]
•
For eveiyday
cleaning,
wipe
the unit with a
soft
diy
cloth,
or
one
that
is
dampened
slightly.
To
remove
dirt that is
more
stubborn,
wipe
using a mild, neutral detergent. Afterwards,
make
sure to
wipe
thoroughly with
a soft cloth.
#
Never
apply benzene,
thinners,
alcohol or
any
like
agents,
to
avoid the
risk
of
discoloration
and
deformation.
#
Within the
unit
is
contained a battery
which
serves
in
maintaining the contents of
memory
while
the
main power
is
off.
The
normal
life
of
this battery
is
5 years or more,
but
it
is
strongly
recommended
that
you change
it
every
5 years as a
rule.
When
it is
time
to
change
the battery, contact a
Roland
Service
Station.
# The
first
time
you
need
to
change the battery could occur before
5 years
have
passed.
#
Please
be aware
that the contents
of
memory may
at
times be
lost;
when
sent for repairs or
when
by
some
chance
a
mal-
function
has occurred. Important
data should be saved on
RAM
card,
or written
down on
paper.
During
repairs,
due
care
is
taken
to
avoid
the loss of data,
however,
in
certain cases, such
as
when
circuitiy related to
memory
itself
is
out of order,
we
regret that
it
may
be
impossible
to restore
the
data.
