Safetyinformation
The construction of the IBM Aptiva Personal Computer provides
extra protection against the risk of electrical shock. The IBM Aptiva
PC has a power cord with a three-prong plug that is required to
ground metal parts. It is the responsibility of the person installing
the computer to connect it to a properly grounded electrical outlet.
Seek professional assistance before using an adapter or extension
cord; these devices could interrupt the grounding circuit.
If the computer is connected to an electrical outlet that is incorrectly
connected to the building wiring, serious electrical shock could
result.
FOR CONTINUED PROTECTION AGAINST THE RISK OF
ELECTRICAL SHOCK:
Connect your computer only to an electrical outlet of the
correct voltage. If you are unsure about the voltage of the
electrical outlet you are using, contact your local power
company.
If your computer has cables other than the power cords, you
must connect them before plugging the power cords into an
electrical outlet. Before removing these cables, you must first
unplug the power cords from the outlet.
Note:
In the UK, by law, the telephone line cable must be
connected after the power cord.
In the UK, by law, the power cord must be
disconnected after the telephone line cable.

If your computer has a telephone connection, do not touch the
telephone cords when there is lightning in the area.
Do not use or store the computer in an area where it can
become wet.
Make sure all replacement parts have characteristics identical
or equivalent to the original parts. Other parts may not have
the same safety features.
Personal injury or electrical shock may result if you undertake
actions other than those specifically described in this book.
This is particularly true if you try to service or repair the power
supply, monitor, or built-in modem. Always refer service or
repairs to qualified service personnel.
Ergonomicinformation
Arranging a comfortable and
productive work area
Caution:
Your computer uses lithium batteries. There may be a
risk of fire, explosion, or burns if the batteries are
handled incorrectly. To ensure safety:
• Do not recharge, disassemble, heat, or incinerate a
lithium battery.
• Replace the battery with an identical or equivalent
type lithium battery.
• Discard used lithium batteries according to local
country dispositions.
v65xahb.book : notices.fm Page xii Friday, January 16, 1998 4:27 PM

Arranging your work area
When you arrange your computer, position your monitor and
keyboard directly in front of you. Try to position the mouse to the
side of the keyboard. The keyboard and mouse should be close to
your body. Avoid reaching too far to use the keyboard and mouse.
The tower is usually kept on the floor under or beside your desk. Be
sure to place it in an area that will not block the space you need to
put your legs under the work surface.
Remember to allow space in your work area for other items you
might use such as reference books, document holders, notebooks,
and diskette or CD-ROM holders.
Choosing a chair
Use a chair that gives you good back support.
When you sit, make sure your thighs are parallel to the floor
and your feet are resting flat on the floor or on a footrest. Your
knees should form a 90-degree angle.
Positioning the monitor
Place the monitor at a comfortable viewing distance, usually
20 to 24 inches away. You can use the length of your arm to
determine a comfortable viewing distance.
Adjust your monitor so the top of the screen is at, or slightly
below, eye level.
Keep the screen clean. For cleaning instructions, refer to the
documentation that came with your monitor.
If you place the monitor near a window, consider using curtains
or blinds to minimize glare from sunlight. Also be sure to keep
the monitor perpendicular to the windows to reduce glare
when the curtains or blinds are open. Try to avoid placing the
monitor directly in front of a window.
Use dim room lighting. If you need more light on your work,
you should position the light so it shines on your work surface
but not onto the monitor screen.
Use the monitor controls to adjust the screen’s brightness and
contrast levels to a comfortable level. You may have to do this
more than once a day if the light in the room changes. For
monitor control adjustment instructions, refer to the
documentation that came with your monitor.
When your eyes focus on a specific object for a long period of
time, they may become tired. If you spend a lot of time looking
at your screen, remember to take frequent breaks. Look up
periodically and focus on an object that is further away. This
will give the muscles in your eyes a chance to relax.
v65xahb.book : notices.fm Page xiii Friday, January 16, 1998 4:27 PM

xiv Notices
Positioning the keyboard
Make sure the keyboard height is comfortable for typing.
When you type, keep your forearms parallel to the floor and
relax your upper arms. Your elbows should form a 90-degree
angle.
Type with a light touch, keeping your hands and fingers
relaxed. Your wrists should also be straight.
If your computer came with a wristrest and you choose to use
it, do not rest your hands on the wristrest or desktop while you
are typing. Instead, use the wristrest only when resting. If you
prefer not to use the wristrest, you may remove it and use the
keyboard without it.
Positioning the mouse
Position your mouse on the same surface as your keyboard so
that they are at the same level. Allow enough space so that
you can use your mouse without stretching or leaning over.
When you use the mouse, hold it lightly with all your fingers
and click gently. Move the mouse with your entire arm instead
of only using your wrist.

computer, refer to the tutorials on your computer or visit the IBM

UnitedStatesmodemregulations
FCC and telephone company
requirements
If your IBM Aptiva Personal Computer comes with a modem
already installed, the following Federal Communications
Commission (FCC) and telephone company requirements apply:
1. The modem adapter card is located inside the back of the
tower. It complies with Part 68 of the FCC rules. A label is
affixed to the built-in modem that contains, among other
things, the FCC registration number, USOC, and Ringer
Equivalency Number (REN) for this equipment. If these
numbers are requested, slide the tower cover forward to see
the label, and provide this information to your telephone
company.
2. The REN is useful to determine the quantity of devices you
may connect to your telephone line and still have those
devices ring when your number is called. In most, but not all
areas, the sum of the RENs of all devices should not exceed
five (5.0). To be certain of the number of devices you may
connect to your line, as determined by the REN, you should
call your local telephone company to determine the maximum
REN for your calling area. The REN for the factory installed
modem in your computer is 0.8B.
3. If the built-in modem causes harm to the telephone network,
the telephone company may discontinue your service tempo-
rarily. If possible, they will notify you in advance; if advance
notice isn’t practical, you will be notified as soon as possible.
You will be advised of your right to file a complaint with the
FCC.
4. Your telephone company may make changes in its facilities,
equipment, operations, or procedures that could affect the
proper operation of your equipment. If they do, you will be
given advance notice so as to give you an opportunity to main-
tain uninterrupted service.
5. If you experience trouble with this built-in modem, check the
“FCC and Telephone Company Requirements” section of the
IBM Statement of Limited Warranty , IBM Program License
Agreement
, and Limited Warranty for Programs document for
informationonobtaining service.Thetelephonecompanymay
ask you to disconnect this equipment from the network until
the problem has been corrected, or until you are sure the
equipment is not malfunctioning.
6. No customer repairs are possible to the modem.
7. The modem may not be used on coin service provided by the
telephone company. Connection to party lines is subject to
state tariffs. Contact your state public utility commission or
corporation commission for information.
8. When ordering network interface (NI) service from the Local
Exchange Carrier, specify service arrangement USOC RJ11C.
9. The Telephone Consumer Protection Act of 1991 makes it
unlawful for any person to use a computer or other electronic
device to send a message via a telephone fax machine unless
such message clearly contains, in a margin at the top or
bottom of each transmitted page, or on the first page of the
transmission, the date and time it is sent and an identification
of the business, or other entity, or other individual sending the
message and the telephone number of the sending machine
ofsuch business, otherentity,or individual.Inordertoprogram
this information into your computer, you should be sure to
follow the installation instructions for your fax software
package.

Canadianmodemregulations
Canadian Department of
Communications certification
label
Notice: The Canadian Department of Communications label
identifies certified equipment. This certification means that the
equipment meets certain telecommunications network protective,
operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is
permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be
installed using an acceptable method of connection. In some
cases, the company’s inside wiring associated with a single line
individual service may be extended by means of a certified
connector assembly (telephone extension cord). The customer
should be aware that compliance with the above conditions may not
prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications
company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical
ground connections of the power utility, telephone lines, and
internal water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.
