• 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.

 

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.

 

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.

 

921

 

• To prevent malfunction and/or damage to speakers or 

other devices, always turn down the volume, and turn off 
the power on all devices before making any connections.

• Wrap the power cord around the cord hook when trans-

porting or storing the unit.

• To prevent injury caused by the unit overturning or being 

dropped, use two or more people to carry the unit 
whenever possible.
