IMPORTANT NOTES
291b
In addition to the items listed under “IMPORTANT
SAFETY INSTRUCTIONS” and “USING THE UNIT
SAFELY” on pages 2 – 4, please read and observe the
following:
Power Supply
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.
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.
308
• Although the LEDs are switched off when the POWER
switch is switched off, this does not mean that the unit has
been completely disconnected from the source of power. If
you need to turn off the power completely, first turn off
the POWER switch, then unplug the power cord from the
power outlet. For this reason, the outlet into which you
choose to connect the power cord’s plug should be one
that is within easy reach.
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.
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 backed up on a DATA
card, 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
501a
• A battery inside the unit powers the internal clock. Once
this battery gets weak, the clock is reset when the unit
turns off. The estimated life expectancy of a battery is
about five years. (The life of a battery changes depending
on the condition.)
When it is time to change the battery, consult with your
retailer, the nearest Roland Service Center, or an autho-
rized 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 DATA card.
552
• Unfortunately, it may be impossible to restore the contents
of data that was stored on a storage device (e.g., hard disk
or DATA card) 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.
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.
