Caution Regarding the Power Supply
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 connected 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” sheet.
