If you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power
outlet. Refer to Power Supply (p. 6).
Grounding terminal
13
Use this to connect the M-480 to an electrical ground.
927
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)
927
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.

replacing the battery, refer to "About the internal lithium battery"
(p. 18).
