About the Power Supply

Connecting the AC Adaptor

Connect the AC Adaptor as shown in the figure below.
Place the AC adaptor so the side with the indicator (see illustration) faces upwards and the side
with textual information faces downwards.
The indicator will light when you plug the AC adaptor into an AC outlet.
Ground terminal
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, or the
metal portions of other objects. This is due to an infinitesimal electrical charge, which is absolutely
harmless. However, if you are concerned about this, connect the ground terminal (see figure)
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" leaflet.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
