POWER-CORD CAUTION
Handle the power cord by the plug. Do not pull out the plug by tugging
the cord and never touch the power cord when your hands are wet as
this could cause a short circuit or electric shock. Do not place the unit,
a piece of furniture, etc., on the power cord, or pinch the cord. Never
make a knot in the cord or tie it with other cords. The power cords
should be routed such that they are not likely to be stepped on. A
damaged power cord can cause fire or give you an electrical shock.
Check the power cord once in a while. When you find it damaged, ask
your nearest PIONEER authorized service center or your dealer for a
replacement. .
MAINTENANCE OF EXTERNAL
SURFACES
* Use a polishing cloth or dry cloth to wipe off dust and dirt.
* When the surfaces are very dirty, wipe with a sof cloth
dipped in some neutral cleanser diluted five or six times with
water, and wrung out well, and then wipe again with a dry
cloth. Do not use furniture wax or cleaners.
Never use thinners, benzine, insecticide sprays and other
chemicals on or near this unit, since these will corrode the
surfaces.
