IMPORTANTS NOTES
291a
In addition to the items listed under “USING THE UNIT SAFELY” on page 5, 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.
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
• Since this device draws a relatively large
amount of electrical current, we recommend
that you use it with the AC adaptor unless AC
power is unavailable. 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 malfunctions and/or damage to
speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other
equipment containing large power trans-
formers) 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 communi-
cations 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.
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.
