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 connected to
it, such as guitars. This is due to an innitesimal
electrical charge, which is absolutely harmless.
However, if you are concerned about this,
connect the ground terminal (see gure) 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” page.
Unsuitable places for connection
• Water pipes (may result in shock or electrocution)
• Gas pipes (may result in re or explosion)
