IMPORTANT NOTES

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.

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.
