Laser Safety Statement (For U.S.A. Only)
(F
or computers with aCD ROM disk driv
e installed.)
The CD R
OM mass storage system is certied as a Class 1laser pro duct
under the U.S. Departmen
tof Health and Human services (DHHS) Radiation
P
erformance Standard according to the
R
adiation Contr
ol for He
alth and Safety
A
ct of 1968.
This means that the mass storage system does not pro duce hazardous
laser radiation. Since laser ligh
temitted inside the mass storage system is
completely conned within protectivehousings and external co
v
ers, the laser
beam cannot escapefrom the mac
hine during an
yphase of user operation.
W
arning
Use of controls, adjustments, or performing procedures
different from those specified in this manual mayresult in
hazardous invisible laser radiation exposure. None of the
mechanisms within the mass storage system contain customer
or field-replaceable parts.
The CD ROM driv
ebecomes aClass 3B laser mechanism
when disassembled. If the CD ROM driv
eis disassembled,
exposure to the invisible laser beam and hazardous invisible
laser radiation could result in blindness.
Do NOT disassemble
the CD R
OM drive for any r
e
ason.
