FCC Statement (For U.S.A. Only)
vi
The Federal Communications Commission (in 47 CFR
15.105) has specified that the following notice be brought to
the attention of the users of this product.
FEDERAL COMMUNICATIONS COMMISSION RADIO
FREQUENCY INTERFERENCE STATEMENT
Note: This equipment has been tested and found to comply
with the limits for a Class A digital device,
pursuant to Part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference
when
the equipment is operated in a commercial environment.
This equipment generates, uses, and can radiate radio
frequency energy and,
if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful
interference in which case
the user will be required to
correct the interference at his own expense.
The end user of this product should be aware
that any
changes or modifications made to this equipment without
the approval of Hewlett-Packard could result in
the product
not meeting the Class A limits, in which case the FCC
could void the user's authority to operate the equipment.

HERSTELLERBESCHEINIGUNG
Hiermit wird bescheinigt,
daB das Gerat in
Ubereinstimmung mit den Bestimmungen von
PostverfUgung 1046/84 funkentstort ist. Der Deutschen
Bundespost wurde das Inverkehrbringen dieses Gerates
angezeigt
und die Berechtigung zur Uberpriifung der Serie
auf Einhaltung der Bestimmungen eingera.umt.
Wird das Gerat innerhalb eines Systems betrieben,
so muS bei Inanspruchnahme der Allgemeinen
Genehmigung FTZ 1046/84 das gesamte System der
oben genannten Genehmigung entsprechen. Wird das
Gera.t innerhalb eines Systems betrieben das mit einer
FTZ-SerienprUfnummer gekennzeichnet ist, und fUr
welches eine Betriebsg~nehmigung vorliegt oder beantragt
wird, so sind in der Regel keine weiteren Schritte
notwendig.

REGULATIONS FOR GERMANY
MANUFACTURER'S DECLARATION
This is to certify
that the equipment is in accordance
with
the Radio Interference Requirements of Directive
FTZ 1046/84. The German Bundespost was notified
that
this equipment was put into circulation and the right to
check
the series for compliance with the requirements was
granted.
If this equipment is to be operated with a system, and if the
General License is being claimed, the complete system must
comply with the General Licensing requirements. If this
equipment is to be operated with a system which has its
own FTZ-Serial-License, and for which
an operating license
has been submitted
or applied, usually no further steps are
necessary.

This apparatus is a class 2 ITE (information apparatus
which may be used in residential and adjacent areas) which
meets the VCCI standards to prevent radio interference in
residential and adjacent areas. However, this apparatus
may become a source of radio interference if used within
close range of radio or television receivers. To ensure
compliance, this apparatus must be operated according to
instructions included with the product.
Communications Statement (For Canada Only)
viii
This digital apparatus does not exceed the Class A limits
for radio noise emissions from digital apparatus as set
out
in the radio interference regulations of the Canadian
Department of Communications.
Le present appareil numerique n'emet pas de bruits

appareils numeriques de Classe A prescrites dans Ie
reglement sur Ie brouillage radioelectrique edicte par Ie
Ministere des Communications du Canada.

HP Series 6000 Models 330S and 660S
Laser Safety Statement (For U.S.A. Only)
This mass storage system is certified as a Class 1 laser
product
under the U.S. Department of Health and Human
Services (DHHS) Radiation Performance Standard
according to
the Radiation Control for Health and Safety
Act of 1968.
This means
that the mass storage system does not produce
hazardous laser radiation. Since laser light emitted inside
the mass storage system is completely confined within
protective housings and external covers,
the laser beam
cannot escape from
the machine during any phase of user
operation.
CDRH Regulations (For U.S.A. Only)
The Center for Devices and Radiological Health (CDRH)
of
the U.S. Food and Drug Administration implemented
regulations for laser products on August
2, 1976. These
regulations apply to laser products manufactured from
August
1, 1976. Compliance is mandatory for products
marketed in
the United States. The label shown below
indicates compliance with CDRH regulations, and
must be
attached to laser products marketed in
the United States.
Made in U.S.A.
This product conforms with CDRH Radiation
Performance Standard,
21 CFR Chapter 1 Subchapter J.
ix

Models 330S and 660S
HP Series 6000
CDRH Regulations Continued (For U.S.A. Only)
x
Use
of controls, adjustments, or performing procedures
other than those specified in this manual may result in
hazardous invisible
laser radiation exposure. None
of the mechanisms within the mass storage system
contain customer or field-replaceable parts.
The CD-ROM drive
becomes a Class 38 laser
mechanism when disassembled. If the CD-ROM disk
drive is disassembled, exposure to the invisible laser
beam and hazardous invisible laser radiation could
result in blindness. Do NOT disassemble the CD-ROM
drive for any reason.
The rewritable optical
disk drive becomes a Class
38 laser mechanism when disassembled. If the
rewritable optical
disk drive is disassembled, exposure
to the invisible laser beam and hazardous invisible
laser radiation could result in blindness. Do NOT
disassemble the rewritable optical disk drive for any
reason.
Please
observe the following warning label, which is
located on the top of the rewritable optical disk drive:
DANGER -Invisible laser radiation when open. Avoid
direct exposure to beam.
