capable of following all the rules essential for the 
safe operation of the unit.

• 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” sheet.

the AC adaptor when plugging into, or

..........................................................................................................
 
103b
 
• Any accumulation of dust between the AC 
adaptor and the power outlet can result in poor 
insulation and lead to fire. Periodically wipe away 
such dust with a dry cloth. Also, disconnect the 
power plug from the power outlet whenever the 
unit is to remain unused for an extended period of 
time.
..........................................................................................................
 
104
 
• 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.

111: Selection
 
• If used improperly, batteries may explode or leak 
and cause damage or injury. In the interest of 
safety, please read and observe the following 
precautions (p. 22 ).
 
1
 
• Carefully follow the installation instructions for 
batteries, and make sure you observe the correct 
polarity.
 
2
 
• Avoid using new batteries together with used 
ones. In addition, avoid mixing different types 
of batteries.
 
3
 
• Remove the batteries whenever the unit is to 
remain unused for an extended period of time.
 
5
 
• If a battery has leaked, use a soft piece of cloth 
or paper towel to wipe all remnants of the 
discharge from the battery compartment. Then 
install new batteries. To avoid inflammation of 
the skin, make sure that none of the battery 
discharge gets onto your hands or skin. Exercise 
the utmost caution so that none of the discharge 
gets near your eyes. Immediately rinse the 
affected area with running water if any of the 
discharge has entered the eyes.
 
6
 
• Never keep batteries together with metallic 
objects such as ballpoint pens, necklaces, 
hairpins, etc.
..........................................................................................................
 
112
 
• Used batteries must be disposed of in compliance 
with whatever regulations for their safe disposal 
that may be observed in the region in which you 
live.
..........................................................................................................
 
118
 
• Should you remove screws, make sure to put them 
in a safe place out of children’s reach, so there is 
no chance of them being swallowed accidentally.
