authorized Roland distributor, as listed on
the “Information” page.
..................................................................................................

008c
• 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.

• Do not excessively twist or bend the power
cord, nor place heavy objects on it. Doing
so can damage the cord, producing severed
elements and short circuits. Damaged cords
are fire and shock hazards!

material, coins, pins); or liquids of any kind
(water, soft drinks, etc.) to penetrate the
unit.
