RISK OF ELECTRIC SHOCK
DO NOT OPEN
Cautions and Warnings
Warning: To reduce the risk of electric shock, do not remove the cover or back
of this unit.
The lightning ash with arrowhead symbol in an equilateral triangle is to
alert the user to the presence of uninsulated “dangerous voltage” within the
product’s enclosure, that may be of sufcient magnitude to constitute a risk of
electric shock.
The exclamation point in an equilateral triangle is intended to alert the user to
the presence of important operating and maintenance instructions.
This product utilizes a Class 1 laser to read Compact Discs. This unit is
equipped with safety switches to avoid exposure when the CD door is open
and safety interlocks are off. Invisible laser radiation is present when the CD
player’s lid is open and the interlock has failed or is off. Important: Avoid direct
exposure to the laser beam at all times. Do not attempt to defeat or bypass the
safety switches.
