Roland F-100 ユーザーズマニュアル

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).

 

302

 

• When the AC adaptor is used for extended periods, both 

the adaptor itself, and the area around the F-100’s DC In 
connector will become somewhat warm; however, this 
does not indicate a malfunction.

 

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.

 

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 inter-
ference.

 

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.

 

357

 

• Do not put anything that contains water (e.g., flower 

vases) on the piano. Also, avoid the use of insecticides, 
perfumes, alcohol, nail polish, spray cans, etc., near the 
unit. Swiftly wipe away any liquid that spills on the unit 
using a dry, soft cloth.

 

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 these off, particularly when strong adhesives have 
been used, can damage the instrument’s exterior finish 
(the stickers provided with this instrument feature a weak 
adhesive).

 

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.

 

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.

 

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.
