●

 

Do not connect this unit to the 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.

●

 

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.

 

308

 

●

 

Although the LEDs are switched off when the POWER switch is 
switched off, this does not mean that the unit has been 
completely disconnected from the source of power. If you 
need to turn off the power completely, first turn off the 
POWER switch, then unplug the power cord from the power 
outlet. For this reason, the outlet into which you choose to 
connect the power cord’s plug should be one that is within 
easy reach and readily accessible.

 

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 temper-
ature 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.

●

 

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.

 

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 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.

 

553

 

●

 

Use a reasonable amount of care when using the unit’s switch 
and when using its jacks and ports. 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.

 

557

 

●

 

A small amount of heat will radiate from the unit during 
normal operation.

 

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.
