Before use
V Placement precautions
o Place the unit in a stable location near the audio system that you
will use with it.
o Do not install this unit in a location that could become hot.
This includes places that are exposed to direct sunlight or near
a radiator, heater, stove or other heating equipment. Moreover,
do not place it on top of an amplifier or other equipment that
generates heat. Doing so could cause discoloration, deformation
or malfunction.
Also avoid locations that are subject to vibrations or exposed to
excessive dust, cold or moisture.
o When installing this unit, leave a little space (at least 3 cm or 1")
between it and walls and other devices in order to allow good
heat dissipation.
If you put it in a rack, for example, leave at least 5 cm (2") open
above it and at least 10 cm (4") open behind it. Failure to provide
these gaps could cause heat to build up inside and result in fire.
o You may stack this unit with a PD-501HR, NT-505 or other
501/503/505 series units. However, if heat should cause the pro-
tection 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.
o Do not place CDs, CD-Rs, cassette tapes, other audio equipment
or other items that are susceptible to heat on top of the unit.
Doing so could damage these items.
o Do not put cloth on top of the unit or place the unit on top of
bedding or thick carpets. Doing so could cause the unit to over-
heat and damage it.
o Do not move the unit during use.
o The voltage supplied to the unit should match the voltage
printed on the rear panel. If you are in any doubt regarding this
matter, consult an electrician.
o Do not open the body of the unit as this might result in damage
to the circuitry or cause electric shock. If a foreign object should
get into the unit, contact your dealer.
o When removing the power plug from the wall outlet, always pull
directly on the plug; never yank on the cord.

Using the remote control
Precautions for use
Misuse of batteries could cause them to rupture
V
or leak, which might result in fire, injury or the
staining of nearby materials. Please carefully read
and observe the precautions on page 3.
o When using the remote control, point it toward the remote con-
trol signal receiver on the main unit from a distance of 5 m (16 ft)
or less. Do not place obstructions between the main unit and the
remote control.
o The remote control might not work if the remote control signal
receiver on the unit is exposed to direct sunlight or bright light. If
this occurs, try moving the unit.
o Beware that use of this remote control could cause the unin-
tentional operation of other devices that can be controlled by
infrared rays.
Installing batteries
Remove the cover from the back of the remote control and insert
two AAA batteries with their ¥/^ oriented as shown in the case.
Replace the cover.
When to replace batteries
If the distance required between the remote and the main unit
decreases or if the unit stops responding to the remote buttons,
replace both batteries with new ones.
Dispose of the used batteries according to the instructions on them
or requirements set by your local municipality.
