matters only.)
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.
This equipment has 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

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 the receiver.
❑ Connect the equipment to an outlet on a
circuit different from that to which the
receiver is connected.
❑ Consult the dealer or an experienced
radio/TV technician for help.
You are cautioned that any changes or
modifications to the computer not expressly
approved in this manual could void your
authority to operate this equipment.
Only peripherals (computer input/output
devices, terminals, printers, etc.) that comply
with FCC Class B limits may be attached to this
computer product. Operation with noncompliant peripherals is likely to result in
interference to radio and television reception.
All cables used to connect peripherals must be
shielded and grounded. Operation with cables
connected to peripherals that are not shielded
and grounded may result in interference to radio
and television reception.
FCC Part 68
This equipment complies with Part 68 of the
FCC rules and the requirements adopted by the
ACTA. On the bottom of this equipment is a
label that contains, among other information, a
product identifier in the format
US:AAAEQ##TXXXX. If requested, this
information must be provided to the telephone
company.
This modem uses the USOC RJ11C telephone
jack.
A telephone plug and jack used to connect this
equipment to the premises wiring and telephone
network must comply with the applicable FCC
Part 68 rules and requirements adopted by the
ACTA.
The REN is used to determine the number of
devices which may be connected to the
telephone line. Excessive RENs on a telephone
line may result in the devices not ringing in
response to an incoming call. In most, but not
all areas, the sum of RENs should not exceed
five (5.0). To be certain of the number of
devices that may be connected to a line, as
determined by the total RENs, contact the
telephone company. For products approved
after July 23, 2001, the REN for this product is
part of the product identifier that has the format
US: AAAEQ##TXXXX. The digits represented
by ## are the REN without a decimal point
(e.g., 03 is a REN of 0.3). For earlier products,
the REN is separately shown on the label.
If this equipment causes harm to the telephone
network, the telephone company will notify you
in advance that temporary discontinuance of
service may be required. But if advance notice
is not practical, the telephone company will
notify the customer as soon as possible. Also,
you will be advised of your right to file a
complaint with the FCC if you believe it is
necessary.
The telephone company may make changes in
its facilities, equipment, operations, or
procedures that could affect the operation of the
equipment. If this happens, the telephone
company will provide advance notice in order
for you to make the necessary modifications in
order to maintain uninterrupted service.
If trouble is experienced with this equipment,
for repair or warranty information, please
contact 1-888-4-SONY-PC (1-888-476-6972),
or write to the Sony Customer Information
Service Center, One Sony Drive, Park Ridge,
NJ 07656. Repair of this equipment should be
made only by a Sony Service Center or Sony

equipment until the problem is resolved.
Connection to party line service is subject to
state tariffs. Contact the state public utility
commission, public service commission, or
corporation commission for information.
If your home has specially wired alarm
equipment connected to the telephone line,
ensure the installation of this equipment does
not disable your alarm equipment. If you have
questions about what will disable alarm
equipment, consult your telephone company or
a qualified installer.
Use a surge arrestor to protect against electrical
surges.

The available scientific evidence does not show that any heal
problems are associated with using low power wireless devices.
There is no proof, however, that these low power wireless devices
are absolutely safe. Low power Wireless devices emit low levels of
radio frequency energy(RF) in the microwave range while being used.
Whereas high levels of RF can produce health effects (by heating
tissue), exposure to low level RF that does not produse heating
effects causes no known adverse health effects. Many studies of low
level RF exposures have not found any biological effects. Some
studies have suggested that some biological effects might occur, but
such findinds have not been cnfirmed by additional research.
The PCG-481L has been tested and found to comply with the
Federal Communications Commission(FCC) guidelines on radio
frequency energy (RF) exposures. The maximum SAR levels
tested for the PCG-481L has been shown to be 0.0687 W/kg

Applying Ergonomics
Your computer is a portable device and can be used in a variety of environments.
Whenever possible, you should apply the following ergonomic considerations:
❑ Position of your computer — Place the computer directly in front of you as
you work. Keep your forearms horizontal, with your wrists in a neutral,
comfortable position while using the keyboard, touch pad, or external
mouse. Let your upper arms hang naturally at your sides. Take breaks during
sessions with your computer. Excessive use of the computer may strain
muscles or tendons.
❑ Furniture and posture — Sit in a chair with good back support and
armrests. Adjust the level of the chair so your feet are flat on the floor. A
footrest may make you more comfortable. Sit in a relaxed, upright posture
and avoid slouching forward or leaning far backward.
❑ Viewing angle of the computer’s display — Tilt the display to find the best
viewing angle. Also try adjusting the brightness setting of the display.
Following these suggestions can reduce eye strain and muscle fatigue.
❑ Lighting — Choose a location where windows and lights do not create glare
or reflection on the display. Use indirect lighting to avoid bright spots on the
display. You can purchase accessories for your display that help reduce
glare. Proper lighting adds to your comfort and work effectiveness.
❑ Placement of an external display — When using an external display, set
the display at a comfortable viewing distance. Make sure the display screen
is at eye level or slightly lower when you are sitting in front of the monitor.
