Placement precautions
Do not put anything on top of the unit.
o
Avoid placing the unit in direct sunlight or close to any
o
source of heat, such as a radiator, heater, open fireplace
or amplifier. Also avoid locations that are subject to vibrations or exposed to excessive dust, cold or moisture.
Place the unit in a stable location near the audio sys-
o
tem that you will use with it.
As the unit could become warm during operation,
o
always leave sufficient space around it for ventilation.
When installing this unit, leave a little space (at least
3 cm or 1.2") between it and walls and other devices
in order to allow good heat dissipation. When placing
it in a rack, for example, leave at least 5 cm (2") open
above it and 10 cm (4") open behind it. Failure to provide these gaps could cause heat to build up inside and
result in fire.
You may stack this unit with a PD-501HR or other 501
o
series units. However, if heat should cause the protection circuit to be activated and sound output stops
suddenly, place this unit on top and with sufficient distance between it and walls and other devices in order
to improve heat dissipation.
Do not move the unit during use.
o
The voltage supplied to the unit should match the volt-
o
age printed on the rear panel. If you are in any doubt
regarding this matter, consult an electrician.
Do not open the body of the unit as this might result
o
in damage to the circuitry or cause electric shock. If a
foreign object should get into the unit, contact your
dealer or TEAC customer service.
When removing the power plug from the wall outlet,
o
always pull directly on the plug; never yank on the cord.
Depending on the electromagnetic waves of television
o
broadcasts, interference might appear on television
screens when this unit’s power is on. This does not
mean that this unit or the TV is malfunctioning. If this
occurs, turn this unit’s power off.
If the surface of the unit becomes dirty, wipe it with a
soft dry cloth. If the unit becomes very dirty, dampen a
soft cloth slightly with a diluted neutral cleanser and thoroughly wring out any excess fluid before using the cloth
to wipe the unit.
Q For your safety, disconnect the power cord from
the socket before cleaning.
Never spray liquid directly on the unit.
o
Do not use thinner or alcohol as they could damage
o
