• Do not force the unit’s power-supply cord to share
an outlet with an unreasonable number of other
devices. Be especially careful when using extension
cords—the total power used by all devices you
have connected to the extension cord’s outlet must
never exceed the power rating (watts/amperes) for
the extension cord. Excessive loads can cause the
insulation on the cord to heat up and eventually
melt through.

• Before using the unit in a foreign country, consult
with your retailer, the nearest Roland Service
Center, or an authorized Roland distributor, as
listed on the "Information" page.

• The unit should be located so that its location or
position does not interfere with its proper venti-
lation.
..........................................................................................................
• Always grasp only the plug on the power-supply
cord when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
• Try to prevent cords and cables from becoming
entangled. Also, all cords and cables should be
placed so they are out of the reach of children.
..........................................................................................................
• Never climb on top of, nor place heavy objects on
the unit.
..........................................................................................................
• Never handle the power cord or its plugs with wet
hands when plugging into, or unplugging from, an
outlet or this unit.
..........................................................................................................
• Before moving the unit, disconnect the power plug
from the outlet, and pull out all cords from external
devices.
..........................................................................................................
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet (Mainte-
nance p. 5).
..........................................................................................................
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out of
the outlet.
..........................................................................................................
• Should you remove the optical connector caps,
make sure to put them in a safe place out of
children's reach, so there is no chance of them
being swallowed accidentally.
