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 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.
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 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 temper-
ature 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 a SD card or on your personal 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.
