Power Supply: Use of Batteries
301
•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
electrical outlet.
302
•The AC adaptor will begin to generate heat after long hours of consecutive use. This is normal, and is not a
cause for concern.
303a
•The use of an AC adaptor is recommended as the unit’s power consumption is relatively high. Should you prefer
to use batteries, please use the alkaline type.
304a
•When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way, you can prevent
malfunction and/or damage to speakers or other devices.
306b
•Batteries are supplied with the unit. The life of these batteries may be limited, however, since their primary
purpose was to enable testing.
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.
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. Damage 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.
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 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
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
important data should always be written down on paper.
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. BOSS/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.
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.
