Stylistic ST4000 Series Tablet PC User’s Guide – Section Three

7. Clean any residue left behind by the protective

coating from the exposed surface of the screen

protector by wiping gently with a soft cotton cloth

dampened with isopropyl alcohol. Wipe the screen

protector with a soft dry cloth to remove any low-

tack adhesive; this will help prevent the pen tip from

squeaking.

The screen protector is now installed.

STORING THE TABLET PC

Store the Stylistic ST4000 Series Tablet PC in the Off

state with a fully charged battery installed. You can store

the Tablet PC in the Off state for about 30 days with a

fully charged battery installed. After this period, the

battery should be recharged or replaced with a charged

battery.

If you intend to store the Tablet PC for a longer period of

time, the small battery that maintains system time may

need to be replaced. Replacement of the clock battery

should only be performed by authorized technicians.

AVOIDING OVERHEATING

The Tablet PC monitors its internal temperature. As the

internal temperature approaches the tolerable limits of

heat-sensitive components, system functions are auto-

matically limited or turned off to prevent damage.

To avoid overheating the Tablet PC, do not obstruct the

air vents on the top and bottom edges of the Tablet PC.

CLEANING THE DISPLAY SCREEN

To clean the Tablet PC display screen, wipe the screen

surface gently using a soft cotton cloth slightly damp-

ened with water or isopropyl alcohol.

TROUBLESHOOTING

Solutions to some common problems are described in

the following sections. If you are experiencing a problem

with your Tablet PC that you cannot solve by taking the

actions described, contact your local help desk or

reseller, or call Fujitsu Service and Support at 1-800-

8Fujitsu (1-800-838-5487) for further assistance.

System Will Not Resume Operation

If the system will not resume operation after system

operation has been suspended, check the following

possible causes:

• The battery may either be defective, or discharged to

a critically low level. When the battery reaches a

critically low level, the system is forced into Suspend-

to-RAM mode to avoid a total system power failure.

To correct this problem, either connect an external

power supply (such as the AC adapter), or install a

charged battery in the Tablet PC.

• The system may be at the critical thermal limit. To

avoid damage to heat-sensitive components, the

system enters Suspend-to-RAM mode when it gets

too hot. System operation cannot be resumed until

the Tablet PC cools off to a tolerable temperature.

Move the Tablet PC to a cooler location.

Display Screen Blank or Difficult to Read

If the display screen on your Tablet PC appears blank or

is unreadable, confirm that the system is running (the

Power icon is displayed continuously on the Status

display), and check the following:

• The system brightness may be set too low, causing

the screen to appear too dark. To change system

brightness, press the Fn button twice to open the

Fujitsu menu. Brightness can be adjusted from the

menu.

• The video timeout may have expired. Tap on the

display screen to reactivate the display. Note that this

is a normal, power-saving feature.

Cursor Is Not Tracking Pen

If the cursor on the screen appears to be misaligned with

the pen or is not accurately tracking the pen, calibrate

the pen. See “Calibrating the Pen” on page 23 for more

information.

Infrared Data Transfer Is Not Working

If you are experiencing problems transferring data over

the system’s infrared interface, note the following:

• Can the IrDA port on the Tablet PC “see” the IrDA

port on the other device? A direct line-of-sight path

must exist between the IrDA port on the Tablet PC

and the IrDA port on the other device.

• The distance between the two devices must not be

more than 3 feet.

• The viewing angle from the IrDA port on the Tablet

PC must not be more than 15 degrees from a center

line between the IrDA port on the Tablet PC and the

IrDA port on the other device.

• The device with which you are trying to

communicate must be compliant with the IrDA

Standard Revision 1.1 (or 1.0).

• It may be necessary for both computers to be using

the same network connection protocols.

CAUTION

The Stylistic ST4000 Series Tablet PC is not waterproof.

Do not pour liquids on the Tablet PC or wash the Tablet

PC with a heavily soaked cloth.
