USING THE UNIT SAFELY
015
•
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.

your retailer, the nearest Roland Service Center, or an
authorized Roland distributor, as listed on the
“Information” (separate leaflet).

this unit.

•
At regular intervals, you should unplug the power
plug and clean it by using a dry cloth to wipe all dust
and other accumulations away from its prongs. Also,
disconnect the power plug from the power outlet
whenever the unit is to remain unused for an
extended period of time. Any accumulation of dust
between the power plug and the power outlet can
result in poor insulation and lead to fire.

keep them in a safe place out of children's reach, so
there is no chance of them being swallowed
accidentally.
