IMPORTANT NOTES

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.
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.
309
• With the factory settings, the VC-30HD's power will
automatically be switched off four hours after the unit
stops receiving input signals. If you don't want the
power to turn off automatically, change the "AUTO
OFF" setting to "OFF" as described on p. 13.
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.
361
• Do not put anything that contains water on this unit.
Also, avoid the use of insecticides, perfumes, alcohol,
nail polish, spray cans, etc., near the unit. Swiftly wipe
away any liquid that spills on the unit using a dry, soft
cloth.
