IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 2
and 3, 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 interference.
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.
355
• To avoid possible breakdown, do not use the unit in a wet
area, such as an area exposed to rain or other moisture.
Maintenance
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or defor-
mation.
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 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.
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.
“BATTERY LOW”
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 in another MIDI device (e.g., a sequencer).
552
• Unfortunately, it may be impossible to restore the contents of
data that was stored in the unit’s memory or another MIDI
device (e.g., a sequencer) once it has been lost. Roland Corpo-
ration 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.
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.
561
• Use only the specified expression pedal (EV-5; sold
separately). By connecting any other expression pedals, you
risk causing malfunction and/or damage to the unit.
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 information
on cable specifications, contact the manufacturer of the
cable.
