Communications Statements
The following statement applies to this product. The statement for other products
intended for use with this product appears in their accompanying documentation.
Federal Communications Commission (FCC) Statement
Note: The IBM 7043 Model 140, Model 150, and Model 240 have been tested and
found to comply with the limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult an authorized dealer or service representative for help.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. Proper cables and connectors are available from
authorized dealers. Neither the provider nor the manufacturer are responsible for
any radio or television interference caused by using other than recommended cables
and connectors or by unauthorized changes or modifications to this equipment.
Unauthorized changes or modifications could void the user's authority to operate the
equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.

European Union (EU) Statement
This product is in conformity with the protection requirements of EU Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to
electromagnetic compatibility. The manufacturer cannot accept responsibility for any
failure to satisfy the protection requirements resulting from a non-recommended
modification of the product, including the fitting of option cards supplied by third
parties. Consult with your dealer or sales representative for details on your specific
hardware.
This product has been tested and found to comply with the limits for Class B
Information Technology Equipment according to CISPR 22 / European Standard EN
55022. The limits for Class B equipment were derived for typical residential
environments to provide reasonable protection against interference with licensed
communication devices.
International Electrotechnical Commission (IEC) Statement
This product has been designed and built to comply with IEC Standard 950.
United Kingdom Telecommunications Safety Requirements
This equipment is manufactured to the International Safety Standard EN60950 and
as such is approved in the UK under the General Approval Number
NS/G/1234/J/100003 for indirect connection to the public telecommunication network.
The network adapter interfaces housed within this equipment are approved
separately, each one having its own independent approval number. These interface
adapters, supplied by the manufacturer, do not use or contain excessive voltages.
An excessive voltage is one which exceeds 70.7 V peak ac or 120 V dc. They
interface with this equipment using Safe Extra Low Voltages only. In order to
maintain the separate (independent) approval of the manufacturer's adapters, it is
essential that other optional cards, not supplied by the manufacturer, do not use
main voltages or any other excessive voltages. Seek advice from a competent
engineer before installing other adapters not supplied by the manufacturer.

Avis de conformité aux normes du ministère des Communications du
Canada
Cet appareil numérique de la classe B respecte toutes les exigences du Réglement
sur le matériel brouilleur du Canada.
Canadian Department of Communications Compliance Statement
This Class B digital apparatus meets the requirements of the Canadian
Interference-Causing Equipment Regulations.
VCCI Statement
The following is a summary of the VCCI Japanese statement in the box above.
This is a Class B product based on the standard of the Voluntary Control Council for
Interference from Information Technology Equipment (VCCI). If this is used near a
radio or television receiver in a domestic environment, it may cause radio
interference. Install and use the equipment according to the instruction manual.
When used near a radio or TV receiver, it may become the cause of radio
interference.
Read the instructions for correct handling.

Laser Safety Information
The optical drive in this system unit is a laser product. The optical drive has a label
that identifies its classification. The label, located on the drive, is shown below.
CLASS 1 LASER PRODUCT
LASER KLASSE 1
LUOKAN 1 LASERLAITE
APPAREIL A LASERDE CLASSE1
IEC 825:1984 CENELEC EN 60 825:1991
The optical drive in this system unit is 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,
the drive is certified to conform to the requirements of the International
Electrotechnical Commission (IEC) 825 (1st edition 1984) and CENELEC EN 60
825:1991 for Class 1 laser products.
CAUTION:
A class 3 laser is contained in the device. Do not attempt to operate the drive
while it is disassembled. Do not attempt to open the covers of the drive as it
is not serviceable and is to be replaced as a unit.
Class 1 laser products are not considered to be hazardous. The optical drive
contains internally a Class 3B gallium-arsenide laser that is nominally 0.14 milliwatts
at 830 nanometers. The design incorporates a combination of enclosures,
electronics, and redundant interlocks such that there is no exposure to laser radiation
above a Class 1 level during normal operation, user maintenance, or servicing
conditions.
