IMPORTANT NOTES

291b

In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2 and 4, 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).

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.

354a

•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.

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.

353

•Observe the following when using the unit’s CD-RW drive. For further details, refer to “Before Using CD-RW drive” (p. 184, 233).

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

•Install the unit on a solid, level surface.

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

Maintenance

401a

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

the unit thoroughly with a soft, dry cloth.

402

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

Repairs and Data

452

•Please be aware that all data contained in the unit’s memory may be lost when the unit is sent for repairs. Important data should always be backed up on a storage device (e.g., CD-R/RW disc or Zip disk) or DAT recorder, 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.

Memory Backup

501b

•This unit contains a battery which powers the unit’s memory circuits while the main power is off. When this battery becomes weak, the message shown below will appear in the display. Once you see this message, have the battery replaced with a fresh one as soon as possible to avoid the loss of all data in memory. To have the battery replaced, consult with your retailer, the nearest Roland Service Center, or an authorized Roland distributor, as listed on the “Information” page.

Additional Precautions

551

•Please be aware that the contents of memory can be irretrievably 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 periodically save a backup copy of important data you have stored in the unit’s memory on a storage device

(e.g., CD-R/RW disc or Zip disk), or DAT recorder.

552

•Unfortunately, it may be impossible to restore the contents of data that was stored on a storage device (e.g., CD-R/ RW disc or Zip disk), or DAT recorder 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.

554

• Never strike or apply strong pressure to the display.

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.
