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 PEN TABLET PC

Store the Stylistic ST4000P Series pen tablet PC in the

Off state with a fully charged battery installed. You can

store the pen 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 pen 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 techni-

cians.

AVOIDING OVERHEATING

The pen tablet PC monitors its internal temperature. As

the internal temperature approaches the tolerable limits

of heat-sensitive components, system functions are

automatically limited or turned off to prevent damage.

To avoid overheating the pen tablet PC, do not obstruct

the air vents on the top and bottom edges of the pen

tablet PC.

CLEANING THE DISPLAY SCREEN

To clean the pen tablet PC display screen, wipe the

screen surface gently using a soft cotton cloth slightly

dampened 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 pen tablet PC that you cannot solve by taking

the actions described, contact your local help desk or

your reseller 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 pen 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 pen tablet PC cools off to a tolerable temperature.

Move the pen tablet PC to a cooler location.

Display Screen Blank or Difficult to Read

If the display screen on your pen 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.

• An external monitor may be selected. Press the Fn

and Display Select buttons to determine whether the

pen tablet PC display screen is selected.

• 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 “To Calibrate 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 pen tablet PC “see” the
