• 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.

 

351

 

• Using the unit near power amplifiers (or 

other equipment containing large power 
transformers) may induce hum. To alleviate 
the problem, change the orientation of this 
unit; or move it farther away from the source 
of interference.

 

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 communi-

cations 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.

 

354a

 

• 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 temperature extremes. Excessive 
heat can deform or discolor the unit.

 

355

 

• To avoid possible breakdown, do not use the 

unit in a wet area, such as an area exposed to 
rain or other moisture.

 

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.

• 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.

 

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.

• 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.
