USING THE UNIT SAFELY
WARNING
Concerning the Auto O function
The power to this unit will be
turned o automatically after
a predetermined amount of
time has passed since it was
last used for playing music, or
its buttons or controls were operated
(Auto O function). If you do not want
the power to be turned o automatically,
disengage the Auto O function (p. 16).
Use only the supplied AC adaptor and
the correct voltage
Be sure to use only the AC adaptor
supplied with the unit. Also,
make sure the line voltage at the
installation matches the input
voltage specied on the AC adaptor’s
body. Other AC adaptors may use a
dierent polarity, or be designed for a
dierent voltage, so their use could result
in damage, malfunction, or electric shock.
WARNING
IMPORTANT NOTES
Placement
• Depending on the material and
temperature of the surface on which you
place the unit, its rubber feet may discolor
or mar the surface.
Repairs and Data
• Before sending the unit away for repairs,
be sure to make a backup of the data
stored within it; or you may prefer to
write down the needed information.
Although we will do our utmost to
preserve the data stored in your unit
when we carry out repairs, in some
cases, such as when the memory section
is physically damaged, restoration of
the stored content may be impossible.
Roland assumes no liability concerning
the restoration of any stored content that
has been lost.
Additional Precautions
• Any data stored within the unit can be
lost as the result of equipment failure,
incorrect operation, etc. To protect
yourself against the irretrievable loss
of data, try to make a habit of creating
regular backups of the data you’ve
stored in the unit.
• Roland assumes no liability concerning
the restoration of any stored content
that has been lost.
• Never strike or apply strong pressure to
the display.
• Use only the specied expression pedal
(FV-500H, FV-500L, EV-30, and Roland
EV-5; sold separately). By connecting any
other expression pedals, you risk causing
malfunction and/or damage to the unit.
• Do not use connection cables that
contain a built-in resistor.
• Depending on the circumstances of a
particular setup, you may experience
a discomforting sensation, or perceive
that the surface feels gritty to the touch
when you touch this device, the metal
portions of other objects, such as guitars.
This is due to an innitesimal electrical
charge, which is absolutely harmless.
However, if you are concerned about
this, connect the ground terminal (see
gure) with an external ground. When
the unit is grounded, a slight hum may
occur, depending on the particulars of
your installation. If you are unsure of the
connection method, contact the nearest
Roland Service Center, or an authorized
Roland distributor, as listed on the
“Information.”
Unsuitable places for connection
• Water pipes (may result in shock or
electrocution)
• Gas pipes (may result in re or
explosion)
• Telephone-line ground or lightning
rod (may be dangerous in the event
of lightning)
CAUTION
Keep small items out of the reach of
children
To prevent accidental ingestion of
the parts listed below, always keep
them out of the reach of small
children.
• Included Parts
Rubber feet (p. 18)
Handle the ground terminal carefully
If you remove the screw from the
ground terminal, be sure to replace
it; don’t leave it lying around where
it could accidentally be swallowed
by small children. When refastening the
screw, make that it is rmly fastened, so it
won’t come loose.
