This unit should be used only with a stand that is 
recommended by Roland.
When using the unit with a rack or stand recommended by 
Roland, the rack or stand must be carefully placed so it is 
level and sure to remain stable. If not using a rack or stand, 
you still need to make sure that any location you choose for 
placing the unit provides a level surface that will properly 
support the unit, and keep it from wobbling.
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 specified on the AC adaptor’s body. Other 
AC adaptors may use a different polarity, or be designed 
for a different voltage, so their use could result in damage, 
malfunction, or electric shock.
Use only the attached power-supply cord. Also, the supplied 
power cord must not be used with any other device.
Do not excessively twist or bend the power cord, nor 
place heavy objects on it. Doing so can damage the cord, 
producing severed elements and short circuits. Damaged 
cords are fire and shock hazards!
This unit, either alone or in combination with an amplifier 
and headphones or speakers, may be capable of producing 
sound levels that could cause permanent hearing loss. Do 
not operate for a long period of time at a high volume level, 
or at a level that is uncomfortable. If you experience any 
hearing loss or ringing in the ears, you should immediately 
stop using the unit, and consult an audiologist.
Do not place containers containing liquid (e.g., flower vases) 
on this product. Never allow foreign objects (e.g., flammable 
objects, coins, wires) or liquids (e.g., water or juice) to enter 
this product. Doing so may cause short circuits, faulty 
operation, or other malfunctions.
Immediately turn the power off, remove the AC adaptor 
from the outlet, and request servicing by your retailer, the
