Roland F-100 owner manual Power Supply, Placement, Maintenance, Additional Precautions

IMPORTANT NOTES

291a

In addition to the items listed under “USING THE UNIT SAFELY” on page 2 and 3, please read and observe the following:

Power Supply

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.

Placement

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).

Maintenance

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.

Additional Precautions

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.
