HP109-PE – Important notes

Important notes

In addition to the items listed under “Important safety instructions” and “Using the unit safely” (p. 2), please read and

observe the following:

Power Supply

• 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 elec-

trical outlet.

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 com-

pletely, 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 and readily

accessible.

Placement

• 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 interfer-

ence.

352a

• This device may interfere with radio and television recep-

tion. Do not use this device in the vicinity of such receiv-

ers.

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 ini-

tiating 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 vehi-

cle, 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. Exces-

sive heat can deform or discolor the unit.

355b

• When moved from one location to another where the

temperature and/or humidity is very different, water

droplets (condensation) may form inside the unit. Dam-

age 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.

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

on the unit for long periods of time. Such objects can dis-

color 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 instru-

ment. Peeling such matter off the instrument may dam-

age the exterior finish.

Maintenance

• 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 oxi-

dization process. If the brass becomes tarnished, polish it

using commercially available metal polisher.

Repairs and Data

• Please be aware that all data contained in the unit’s mem-

ory may be lost when the unit is sent for repairs. Impor-

tant data should always be backed up in another MIDI

device (e.g., a sequencer), or written down on paper

(when possible). 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.

Additional Precautions

• Please be aware that the contents of memory can be irre-

trievably lost as a result of a malfunction, or the improper

operation of the unit. To protect yourself against the risk

of loosing important data, we recommend that you peri-

odically save a backup copy of important data you have

stored in the unit’s memory in another MIDI device (e.g.,

a sequencer).

552

• Unfortunately, it may be impossible to restore the con-

tents of data that was stored in the unit’s memory and

another MIDI device (e.g., a sequencer) 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 mal-

functions.
