Laser compliance statement
Some IBM Personal Computer models are equipped from the factory with a
CD-ROM drive or a DVD-ROM drive. CD-ROM drives and DVD-ROM drives are
also sold separately as options. CD-ROM drives and DVD-ROM drives are laser
products. These drives are certified in the U.S. to conform to the requirements of
the Department of Health and Human Services 21 Code of Federal Regulations
(DHHS 21 CFR) Subchapter J for Class 1 laser products. Elsewhere, these drives
are certified to conform to the requirements of the International Electrotechnical
Commission (IEC) 825 and CENELEC EN 60 825 for Class 1 laser products.
When a CD-ROM drive or a DVD-ROM drive is installed, note the following
handling instructions.
CAUTION:
Use of controls or adjustments or performance of procedures other than those
specified herein might result in hazardous radiation exposure.
Removing the covers of the CD-ROM drive or DVD-ROM drive could result in
exposure to hazardous laser radiation. There are no serviceable parts inside the
CD-ROM drive or DVD-ROM drive. Do not remove the drive covers.
Some CD-ROM drives and DVD-ROM drives contain an embedded Class 3A or
Class 3B laser diode. Note the following statement.
Safety Informationvii
DANGER
Laser radiation when open. Do not stare into the beam, do not view directly with optical
instruments, and avoid direct exposure to the beam.
DANGER:
Certains modèles d’ordinateurs personnels sont équipésd’origine d’une unité de
CD-ROM ou de DVD-ROM. Mais ces unités sont également vendues séparément
en tant qu’options. L’unité de CD-ROM/DVD-ROM est un appareil à laser. Aux
État-Unis, l’unité de CD-ROM/DVD-ROM est certifiée conforme aux normes
indiquées dans le sous-chapitre J du DHHS 21 CFR relatif aux produits à laser de
classe 1. Dans les autres pays, elle est certifiée être un produit à laser de classe 1
conforme aux normes CEI 825 et CENELEC EN 60 825.
Lorsqu’une unité de CD-ROM/DVD-ROM est installée, tenez compte des
remarques suivantes:
ATTENTION: Pour éviter tout risque d’exposition au rayon laser, respectez les
consignes de réglage et d’utilisation des commandes, ainsi que les procédures
décrites.
L’ouverture de l’unité de CD-ROM/DVD-ROM peut entraîner un risque
d’exposition au rayon laser. Pour toute intervention, faites appel à du personnel
qualifié.
Certaines unités de CD-ROM/DVD-ROM peuvent contenir une diode à laser de
classe 3A ou 3B. Tenez compte de la consigne qui suit:
DANGER
Rayonnement laser lorsque le carter est ouvert. Évitez toute exposition directe des yeux
au rayon laser. Évitez de regarder fixement le faisceau ou de l’observer à l’aide
d’instruments optiques.

Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer
components and options.
When you add an option, do not open the static-protective package containing the
option until you are instructed to do so.
When you handle options and other computer components, take these precautions
to avoid static electricity damage:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Always handle components carefully. Handle adapters and memory modules by
the edges. Never touch any exposed circuitry.
v Prevent others from touching components.
v When you install a new option, touch the static-protective package containing
the option to a metal expansion-slot cover or other unpainted metal surface on
the computer for at least two seconds. This reduces static electricity in the
package and your body.
v When possible, remove the option and install it directly in the computer without
setting the option down. When this is not possible, place the static-protective
package that the option came in on a smooth, level surface and place the option
on it.
v Do not place the option on the computer cover or other metal surface.
