008c
NOTE
Be sure to use only the AC adaptor supplied with the unit.
Also, make sure the line voltage at the installation matches
the input voltage specified on the AC adaptor’s body.
Other AC adaptors may use a different polarity, or be
designed for a different voltage, so their use could result
in damage, malfunction, or electric shock
924
NOTE
To prevent the inadvertent disruption of power to your unit
(should the plug be pulled out accidentally), and to avoid
applying undue stress to the AC adaptor jack, anchor the
power cord using the cord hook, as shown in the
illustration.
Even if the cord is fastened, strong tension applied to the
cord may cause it to be damaged or broken. Be careful
not to pull the cord accidentally, or to apply strong
pressure to it.
927
NOTE
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. 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)
