FCC NOTICES
Notice to Users of Radios and Television
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 that is
on a different circuit than the receiver.
• Consult the dealer or an experienced radio/
TV technician for help.
Shielded interconnect cables must be employed
with this equipment to ensure compliance with
the pertinent RF emission limits governing this
device.
Notice to Users of the US Telephone Network*
Your Stylistic maybe supplied with an internal
modern which complies with Part 68 of the FCC
rules. On this Tablet PC is a label that contains
the FCC Registration Number and the Ringer
Equivalence Number(REN) for this equipment
*For model with modern only
among other information. If requested the user
must provide their telephone company with the
following information:
1. The telephone number to which the
Tablet PC is connected.
2. The Ringer Equivalence Number(REN)
for this equipment.
3. That the equipment requires a standard
modualar jack type USOC RJ-11C which
is FCC Part 68 compliant.
4. The FCC Registration Number.
This equipment is designed to be connected
to the telephone network or premises wiring
using a standard modular jack type USOC
RJ-11C which is FCC Part 68 68 compliant
and a line cord between the modem and the
telephone network with a minimum of 26AWG.
The REN is used to determine the number
of devices that you may connect to your
telephone line and still have all of those
devices ring when your number is called. Too
many devices on one line may result in failure
to ring in response to an incoming call. In
most, but not all, areas the sum of the RENs
of all of the devices should not exceed ve(5).
To be certain of the number of devives you
may connect to your line, as determined by the
RENs, contact your local telephone company.
If this equipment causes harm to the
telephone network your telephone company
may discontinue your service temporarily. If
possible, they will notify you in advance. If
advance notice is not practical they will notify
you as soon as possible. You will also be
advised of your right to file a complaint with
the FCC.

ENERGY STAR®
Compliance
Notice to Users of Radios and
Television
(The following is pending
certicationattime o f publication). Your Fujitsu
system is an ENERGY STAR® quali ed
mobile PC. By choosing a computer with
the latest energysaving technology, you’re
helping to preserve our environment for future
generations.ENERGY STAR is a joint program
of the U.S. Environmental Protection Agency,
U.S. Department of Energy, Natural Resources
Canada, and other governments around the
world helping us save money while protecting
the environment through energy ef cient
products and practices. With energy costs and
global warming top-of-mind for consumers,
Fujitsu is committed to offering solutions that
help consumers conserve energy and improve
the quality of our environment.
Sleep Mode:
You will notice that your computer is initially set
so that the display turns off after 15 minutes
of user inactivity, and the computer goes into
Sleep mode after 20 minutes of user inactivity.
When going into Sleep mode, the computer
also reduces the speed of any active Ethernet
network links. To “wake” the computer from
Sleep mode, press the Suspend/ Resume
Button.
Energy saving benefits:
Fujitsu ENERGY STAR quali ed mobile PCs
use about half as much electricity as standard
equipment – saving half in utility costs. But
more than that, ENERGY STAR also makes a
difference for the environment. Did you know
that the average house can be responsible for
twice the greenhouse gas emissions as the
average car? Thats because every time you ip
on a light switch, run your dishwasher, or turn
on your PC, you use energy, which means more
greenhouse gas emissions from power plants.
So the more energy we can save through
energy ef ciency, the more we help to reduce
greenhouse gases and the risks of global
warming. To learn more about the important
ENERGY STAR program,

WARNING
FOR SAFETY REASONS, ONLY CONNECT
EQUIPMENT WITH A TELECOMMUNICATIONS
COMPLIANCE LABEL. THIS INCLUDES
CUSTOMER EQUIPMENT PREVIOUSLY
LABELLED PERMITTED OR CERTIFIED.
Connection of Non Certified/ Approved
peripherals may result in the equipment
operating outisde the Australian EMI
Standards.
Modems connected to the Australian
telecommunications network must be operated
in accordance with the Labelling Notice. This
modem has benn specifically configured to
ensure compliance with the ACMA standards.
Do not adjust your modem or software outside
the values indicated below. To do so would
result in your modem being operated in a non-
compliant manner.
The unit shall be connected to Telecommunications
Network through a line cord, which meets the
requirements of ACMA AS/ ACIF S008:2006.
The equipment shall be powered through an
Australian Approved mains cord set. When the
Secondary Landscape Orientation of the Tablet
PC is held close to the body, the antenna must
be in closed condition to avoid physical damage
to the Antenna.
Call Attempts / Retries:
Applications software shall be configured so
that no more than 3 attempts are made to
establish a connection to a given number(Note:
if the modern can detect serice tones, up to 10
attempts can be made). If the call sequence is
unsuccessful, there shall be a delay of at least
30 minutes before attempting to call the number
again.
Failure to set the modem and any application
so f tw a re u s ed wi th th e mod e m, t o t he
values shown above will result in the modem
being operated in a non-compliant manner.
Consequently, this would be in violation of the
Labelling Notice for 1997 prescribes penalties

Using Your LIFEBOOK
RUNNING LIFEBOOK
ON ITS BATTERY
Recharging the battery
•
•
Before using the supplied battery
pack fo r th e ve ry  rst time a fte r
purchase, remember to charge it fully.
If a charged battery has not been
recharged for more than a month,
charge it fully before using it.
When the battery is fully charged while
the notebook is in power off mode, the
Battery Charging Indicator turns off.
•
•
•
•
•
When the battery is 90% or more
charged, it cannot be recharged even if
the AC adapter is connected. The battery
can be recharged when its power level(i.e.
remaining battery life) is 89% or less. This
is a mechanism to protect and extend the
battery life.
When a notebook is turned off, the Battery
Level LED indicator goes off immediately
if the battery is completely charged.
The chargeability of the battery degrades
when it is used in an extremely hot or cold
place.
When the battery is very hot, for
example, immediately after long usage
of the notebook, the battery protection
feature may be activated to prevent the
battery from being recharged. When the
temperature decreases, the notebook
automatically begins to charge the battery.
When an optional modular bay battery
is installed, it is charged along with
the internal standard battery. (Optional
modular bay battery is applicable to
selected models only.)
Connect the AC adapter to your notebook
The moment you connect an AC adapter
to your notebook, the notebook begins to
charge the internal standard battery pack.
When the battery level indicator turns off
after the battery is completely charged,
(while the notebook is in off mode)
disconnect the AC adapter from the
notebook.
