301

 

• Do not use this unit on the same power circuit with any 

device that will generate line noise (such as an electric 
motor or variable lighting system).

 

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 LCD and 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.

 

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 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.

 

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 temperature 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.

 

355

 

• To avoid possible breakdown, do not use the unit in a wet 

area, such as an area exposed to rain or other moisture.

 

356

 

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

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

 

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.

 

359

 

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

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

 

401b

 

• To clean the unit, use a dry, soft cloth; or one that is 

slightly dampened. Try to wipe the entire surface using an 
equal amount of strength, moving the cloth along with the 
grain of the wood. Rubbing too hard in the same area can 
damage the finish.

 

402

 

• Never use benzine, thinners, alcohol or solvents of any 

kind, to avoid the possibility of discoloration and/or 
deformation.

• The pedals of this unit are made of brass.

Brass eventually darkens as the result of the natural 
oxidization process. If the brass becomes tarnished, polish 
it using commercially available metal polisher.

 

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 tho

 

559b

 

•  When you need to transport the unit, pack it in shock-

absorbent material. Transporting the unit without doing so 
can cause it to become scratched or damaged, and could 
lead to malfunction.

 

560

 

• Do not apply undue force to the music stand while it is in 

use.(HP-7)

 

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.

 

565

 

• Before opening or closing the keyboard lid, always make 

sure that no pets or other small animals are located on top 
of the instrument (in particular, they should be kept away 
from the keyboard and its lid). Otherwise, due to the struc-
tural design of this instrument, small pets or other animals 
could end up getting trapped inside it. If such a situation is 
encountered, you must immediately switch off the power 
and disconnect the power cord from the outlet. You should 
then consult with the retailer from whom the instrument 
was purchased, or contact the nearest Roland Service 
Center.
