IMPORTANT NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 2–3, please read and observe the
following:
Power Supply: Use of Batteries
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).
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.
304b
• Batteries should always be installed or replaced before
connecting any other devices. 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 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.
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 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 written down on paper,
”Setting Memo.” 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 you
periodically save a backup copy of important data you
have stored in the unit’s memory written down on paper,
”Setting Memo.”
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. 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.
