1. Important notes

Power Supply

•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).

•Before connecting the HP-1 to other devices, turn off the power to all units. This will help prevent malfunc- tions and/or damage to speakers or other devices.

Placement

•Using the unit near power ampliﬁers (or other equip- ment containing large power transformers) may induce hum. To alleviate the problem, change the ori- entation of this unit; or move it farther away from the source of interference.

•This device may interfere with radio and television reception. Do not use this device in the vicinity of such receivers.

•Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicin- ity of this unit. Such noise could occur when receiving or initiating 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.

•Do not expose the instrument to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehicle, or otherwise subject it to tempera- ture 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 spot- lights to shine upon the same area of the unit for extended periods of time. Excessive heat can deform or discolor the unit.

•To avoid possible breakdown, do not use the HP-1 in a wet area, such as an area exposed to rain or other moisture.

•Do not allow rubber, vinyl, or similar materials to remain on the HP-1 for long periods of time. Such objects can discolor or otherwise harmfully affect the ﬁnish.

•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.

•Do not allow objects to remain on the keyboard. This can be the cause of malfunction, such as keys ceasing to produce sound.

•Do not paste stickers, decals, or the like to this instru- ment. Peeling such matter off the instrument may damage 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.

•Never use benzine, thinners, alcohol or solvents of any kind, to avoid the possibility of discoloration and/or deformation.

Additional Precautions

•Use a reasonable amount of care when using the HP-1’s buttons, sliders, or other controls; and when using its jacks and connectors. Rough handling can lead to malfunctions.

•When connecting/disconnecting 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.

•A small amount of heat will radiate from the unit dur- ing normal operation.

•To avoid disturbing your neighbors, try to keep the unit’s volume at reasonable levels. You may prefer to use headphones.

•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.

•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 information on cable speciﬁcations, con- tact the manufacturer of the cable.
