IMPORTANT NOTES

291b
In addition to the items listed under "IMPORTANT SAFETY INSTRUCTIONS" and "USING THE UNIT SAFELY" on pages 2,
3, 4 and 5, please read and observe the following:
Power Supply
301
• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled by an
inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this unit
to malfunction or may produce audible noise. If it is not
practical to use a separate electrical outlet, connect a power
supply noise filter between this unit and the electrical outlet.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions
and/or damage to speakers or other devices.
308
• Although the LEDs are switched off when the POWER
switch is switched off, this does not mean that the unit has
been completely disconnected from the source of power. If
you need to turn off the power completely, first turn off
the POWER switch, then unplug the power cord from the
power outlet. For this reason, the outlet into which you
choose to connect the power cord's plug should be one
that is within easy reach and readily accessible.

Maintenance

401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to wipe
the unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any kind,
to avoid the possibility of discoloration and/or deformation.
109a
• Before cleaning the unit, turn off the power and
unplug the power cord from the outlet.
..........................................................................................................
110a
• Whenever you suspect the possibility of lightning
in your area, pull the plug on the power cord out
of the outlet.
..........................................................................................................
119
• The cooling vents on either side of the unit may
become hot, so take care to avoid burns.
..........................................................................................................
121
• Do not remove the speaker grille and speaker by
any means. Speaker not user replaceable. Shock
hazardous voltages and currents are present
inside the enclosure.
Additional Precautions
553
• Use a reasonable amount of care when using the unit's
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable's
internal elements.
557
• A small amount of heat will radiate from the unit during
normal operation.
558a
• To avoid disturbing your neighbors, try to keep the unit's
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.
562
• Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the
following precautions.
• Some connection cables contain resistors. Do not use
cables that incorporate resistors for connecting to this
unit. The use of such cables can cause the sound level
to be extremely low, or impossible to hear. For infor-
mation on cable specifications, contact the manufac-
turer of the cable.
• Wrap the power cord around the cord hook when trans-
porting or storing the unit.
