Do not ground the M-480 to locations such as the following:
•
Water pipe (doing so may cause electrical shock)
•
Gas pipes (doing so may cause fire or explosion)
•
Telephone ground or lightning rod (hazardous if
lightning occurs)

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, microphones connected to it, or the metal portions
of other objects, such as guitars. 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.

If the battery runs down, you’ll need to replace it. For details on
replacing the battery, refer to “About the internal lithium battery”
