• 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 condi-
tioner), 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 LED 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.

 

352a

 

• This device may interfere with radio and television 

reception. Do not use this device in the vicinity of 
such receivers.

 

352b

 

• Noise may be produced if wireless communications 

devices, such as cell phones, are operated in the 
vicinity of this unit. Such noise could occur when 
receiving or initiating a call, or while conversing. 
Should you experience such problems, you should 
relocate such wireless devices so they are at a 
greater distance from this unit, or switch them off.

 

354b

 

• Do not expose the unit to direct sunlight, place it 

near devices that radiate heat, leave it inside an 
enclosed vehicle, or otherwise subject it to temper-
ature extremes. Also, do not allow lighting devices 
that normally are used while their light source is 
very close to the unit (such as a piano light), or 
powerful spotlights to shine upon the same area of 
the unit for extended periods of time. Excessive heat 
can deform or discolor the unit.

 

355b

 

• When moved from one location to another where 

the temperature and/or humidity is very different, 
water droplets (condensation) may form inside the 
unit. Damage or malfunction may result if you 
attempt to use the unit in this condition. Therefore, 
before using the unit, you must allow it to stand for 
several hours, until the condensation has completely 
evaporated.

 

356

 

• Do not allow rubber, vinyl, or similar materials to 

remain on the unit for long periods of time. Such 
objects can discolor or otherwise harmfully affect the 
finish.

 

359

 

• Do not paste stickers, decals, or the like to this 

instrument. Peeling such matter off the instrument 
may damage the exterior finish.

 

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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, 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 information on cable 
specifications, contact the manufacturer of the 
cable.
