IMPORTANT NOTES
Power Supply: Use of Batteries
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.
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.
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.
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.
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.
Additional Precautions
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.
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
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.
