10. Ground terminal
In some cases, depending on the environment in which the
unit is installed, the surface of the panel may sometimes feel
rough and grainy. 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” page.
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)
