Do not force the unit’s power-supply cord to share  
an outlet with an unreasonable number of other  
devices. Be especially careful when using extension  
cords—the total power used by all devices you  
have connected to the extension cord’s outlet must  
never exceed the power rating (watts/amperes) for  
the extension cord. Excessive loads can cause the  
insulation on the cord to heat up and eventually  
melt through.

The unit and the AC adaptor should be located so  
• Remove the batteries whenever the unit is to  
remain unused for an extended period of time.  
their location or position does not interfere with  
their proper ventilation.  
• If a battery has leaked, use a soft piece of cloth  
or paper towel to wipe all remnants of the  
discharge from the battery compartment. Then  
install new batteries. To avoid inflammation of  
the skin, make sure that none of the battery  
discharge gets onto your hands or skin. Exercise  
the utmost caution so that none of the discharge  
gets near your eyes. Immediately rinse the  
affected area with running water if any of the  
discharge has entered the eyes.  
................................................................................................  
102d  
Always grasp only the output plug or the body of  
the AC adaptor when plugging into, or

At regular intervals, you should unplug the AC  
adaptor and clean it by using a dry cloth to wipe  
all dust and other accumulations away from its  
prongs. Also, disconnect the power plug from the  
power outlet whenever the unit is to remain  
unused for an extended period of time. Any  
accumulation of dust between the power plug and  
the power outlet can result in poor insulation and  
lead to fire.

Important Notes  
291a  
In addition to the items listed under “USING THE UNIT SAFELY” on page 2-3, please read and observe the following:  
Power Supply  
Placement  
301  
352a  
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.  
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 initi-  
ating 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.  
302  
354a  
The AC adaptor will begin to generate heat after long  
hours of consecutive use. This is normal, and is not a cause  
for concern.  
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.  
303a  
The use of an AC adaptor is recommended as the unit’s  
355b  
power consumption is relatively high. Should you prefer to  
use batteries, please use the alkaline type.  
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.  
304a  
When installing or replacing batteries, always turn off the  
power on this unit and disconnect any other devices you  
may have connected. This way, you can prevent  
malfunction and/or damage to speakers or other devices.  
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.  
358  
Do not allow objects to remain on top of the keyboard. This  
can be the cause of malfunction, such as keys ceasing to  
produce sound.  
Maintenance  
401a  
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 defor-  
mation.  
Repairs and Data  
452  
Please be aware that all data contained in the unit's  
memory may be lost when the unit is sent for repairs.  
Important data should always be written down on paper.  
During repairs, due care is taken to avoid the loss of data.  
However, in certain cases (such as when circuitry related to  
memory itself is out of order), we regret that it may not be  
possible to restore the data, and Roland assumes no  
liability concerning such loss of data.  
4
 
Additional Precautions  
551  
Please be aware that the contents of memory can be  
irretrievably lost as a result of a malfunction, or the  
improper operation of the unit. To protect yourself against  
the risk of losing important data, we recommend that you  
periodically write down important data you have stored in  
the unit's memory on paper.  
552  
Unfortunately, it may be impossible to restore the contents  
of data that was stored in the unit’s memory once it has  
been lost. Roland Corporation assumes no liability  
concerning such loss of data.  
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.  
558b  
To avoid disturbing your neighbors, try to keep the unit’s  
volume at reasonable levels (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.  
561  
Use only the specified expression pedal (EV-5; sold  
separately). By connecting any other expression pedals,  
you risk causing malfunction and/or damage to the unit.  
Handling CD-ROMs  
801  
Avoid touching or scratching the shiny underside  
(encoded surface) of the disc. Damaged or dirty CD-ROM  
discs may not be read properly. Keep your discs clean  
using a commercially available CD cleaner.
