RISK OF ELECTRIC SHOCK

DO NOT OPEN

The exclamation point within an equilateral triangle is 
intended to alert the user to the presence of important 
operating and maintenance (servicing) instructions in 
the literature accompanying the appliance.

This symbol indicates that this product incorporates 
double insulation between hazardous mains voltage 
and user accessible parts.

The lightning flash with arrowhead symbol, within an 
equilateral triangle, is intended to alert the user to the 
presence of uninsulated “dangerous voltage” within the 
product’s enclosure that may be of sufficient magnitude 
to constitute a risk of electric shock to persons.

This product utilizes a Class 1 laser to read Compact 
Discs. This laser Compact Disc Player is equipped with 
safety switches to avoid exposure when the CD door 
is open and the safety interlocks are defeated. Invisible 
laser radiation is present when the CD Player’s lid is 
open and the system’s interlock has failed or been 
defeated. It is very important that you avoid direct 
exposure to the laser beam at all times. Please do not 
attempt to defeat or bypass the safety switches.
