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 condi-
tioner), 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.
307
• Before connecting this unit to other devices, turn off
the power to all units. This will help prevent malfunc-
tions 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 initiating 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.
360
• Depending on the material and temperature of the
surface on which you place the unit, its rubber feet
may discolor or mar the surface.
You can place a piece of felt or cloth under the rubber
feet to prevent this from happening. If you do so,
please make sure that the unit will not slip or move
accidentally.
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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, 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 your
computer, 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
503
• If the unit's power is not turned on for several days the
contents of certain items you've set, such as the date
and time, will be lost.
