1. Important notes

KR-3–

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY”, please read and observe the following:

❏Power supply

•Before connecting the KR-3 to other devices, turn off the power to all units. This will help prevent malfunctions and/or damage .

•Do not use the KR-3 on the same power circuit with any device that will generate line noise; an electric motor or variable lighting system for example.

❏Placement

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

•Do not place the instrument near devices that produce a strong magnetic field (e.g., loudspeakers).

•Install the instrument on a solid, level surface.

•Do not move the instrument or subject it to vibration while the disk drive is operating.

•Do not expose the KR-3 to direct sunlight, place it near devices that radiate heat, leave it inside an enclosed vehi- cle, or otherwise subject it to temperature extremes. Excessive heat can deform or discolor the unit.

❏Maintenance

•For everyday cleaning wipe the instrument with a soft, dry cloth or one that has been slightly dampened with water. To remove stubborn dirt, use a mild, non-abrasive detergent. Afterwards, be sure to wipe the instrument thoroughly with a soft, dry cloth.

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

❏Repairs and data backup

•Please be aware that data contained in the KR-3’s mem- ory may be lost when the instrument is sent for repairs. Important data should always be backed up on a floppy disk, or written down on paper (if possible). During repairs, due care is taken to avoid the loss of data. How- ever, 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 instrument. To protect yourself against the risk of losing important data, we recommend that you periodically save a backup copy of important data to a high-quality floppy disk. Bear in mind, however, that it may be impossible to restore the contents of data that was stored on a floppy disk. Roland Corporation assumes no liability concerning such loss of data.

•Use a reasonable amount of care when operating the instrument’s buttons, sliders other controls. Rough han- dling can lead to malfunctions.

•Never strike or apply strong pressure to the display.

•When connecting/disconnecting all cables, grasp the con- nector itself—never pull on the cable. This way you will avoid causing shorts, or damage to the cable wires.

•A small amount of heat will radiate from the instrument during normal operation.

•To avoid disturbing your neighbors, try to keep the instrument’s volume at a reasonable level. At times, it may be preferable to use headphones.

•When you need to transport the KR-3, package it in the box (including padding) that it came in or use a hard or soft case.

Before using floppy disks

❏Floppy disk drive

•Avoid using the KR-3 immediately after it has been moved to a location with a significantly higher or lower level of humidity. Rapid changes in the environment can cause condensation to form inside the drive, which will adversely affect the operation of the drive and/or damage floppy disks. When the instrument has been moved, switch it on and wait at least one hour before using the disk drive.

•To insert a disk, push it gently but firmly into the drive— it will click into place. To remove a disk, press the EJECT button.

•Never attempt to remove a floppy disk from the drive while the drive is operating (the indicator is brightly lit); damage could result to both the disk and the drive.

•Remove any disk from the drive before powering up or down.

•To prevent damage to the disk drive’s heads, always try to hold the floppy disk in a level position (not tilted in any direction) while inserting it into the drive.

❏Handling floppy disks

•Floppy disks contain a plastic disk with a thin magnetic coating. Microscopic precision is required to enable stor- age of large amounts of data on such a small surface area. To preserve their integrity, please observe the following when handling floppy disks:

•Never touch the magnetic medium inside the disk.

•Do not use or store floppy disks in dirty or dusty areas.

•Do not subject floppy disks to temperature extremes (e.g., direct sunlight in an enclosed vehicle). Recom- mended temperature range: 10 to 50° C (50 to 122° F).

•Do not expose floppy disks to strong magnetic fields, such as those generated by loudspeakers.
