Operation
Display
Avoid using water when cleaning the panel.  Ingredients included in water may leave 
scratches and reduce readability of the screen.

zAvoid rubbing off dust/dirt with cloth since it may leave scratch on the screen. 
Sweep dust/dirt with fine brush, then wipe it with a dry soft cloth used for cleaning 
glasses.

zApply camera lens cleaner on a soft gauze and clean it with gentle force. Then, wipe  
with a dry soft cloth used for cleaning glasses. 
Areas excluding the display
Wipe these areas with a soft cloth, after applying water or detergent diluted with water 
to the soft cloth and firmly wringing out excess water.
Touch Pad (Îpage 18)
CAUTION
zDo not use benzene, thinner, or rubbing alcohol.  Doing so may adversely affect 
the surface, e.g., discoloration.  In addition, do not use commercially-available 
household cleaners and cosmetics, as they may contain components harmful to 
the surface.
zDo not directly add or spray water or detergent.  If liquid enters the inside of the 
computer, it may cause it to work improperly or be damaged.
Users are advised to purchase the latest versions of virus protection software 
and use them regularly.
We recommend you run the software:
zWhen booting your computer.
zAfter receiving data.
We recommend that you check data received on disks or from external sources, such 
as data downloaded from the Internet, e-mail, etc.  (For compressed files, uncompress 
them before running a check).
You can use the latest patches and service packs for Windows with the following 
menus. 
Do not apply “Driver Updates” even if a message to update a driver appears. If a 
driver update is required, contact Panasonic Technical Support. (Îpage 37)
[start] - [All Programs] - [Windows Update]
Pay strict attention to the following points to avoid damage to the computer, peripheral 
devices, cables, etc.  Also, in addition to following this manual and the Reference Man-
ual, carefully read the instruction manuals for the peripheral devices being used.
zUse only peripheral devices that conform to the computer’s specifications.
zConnect the devices properly, paying close attention to the condition and position of 
the connectors.
zIf a connection cannot be made easily, do not apply undue force; check once more 
to confirm the condition and position of the connector (alignment of pins, etc.) .
zIf the connector has holding screws, fasten the screws firmly.
zDo not carry the computer with cables attached, and do not pull on the cables force-
fully.

Operation
zDo not expose your computer to shock.
Use care when handling your computer, shock may damage your hard disk or make 
your software applications and data unusable.
zDo not power down your computer while software applications are running or 
hard disk drive indicator   is on. 
Properly shut Windows down to avoid problems.
zSave all valuable data to disks.
Backing up data to disks will limit damage should trouble occur to your computer or 
should you inadvertently change or erase data.
zUse the security function for all important data. (⇒ Reference Manual “Security 
Measures”)
Hard Disk Lock
When the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to 
the hard disk when the hard disk is installed in a different computer, since a password is 
also set for the hard disk. When the hard disk is returned to the original computer, you 
can read/write data as before.  In this case, however, make the settings in the Setup 
Utility exactly the same as they were before the hard disk was removed.  (Note that this 
Hard Disk Lock does not guarantee the complete protection of data.) (⇒ Reference 
Manual “Security Measures”)
zDo not power down your computer or press the floppy disk drive eject button 
while the MP indicator   is on.
Doing so may damage the data on the floppy disk and render the floppy disk use-
less.
zUse care when handling floppy disks.
To protect the data on your floppy disks or to prevent a floppy disk from becoming 
stuck in your computer, avoid the following:
 Sliding the shutter on the floppy disk manually. 
 Exposing the floppy disk to a magnetic field.
 Storing the floppy disk in locations prone to high temperatures, low pitched noise, 
dampness, or dust.
 Applying more than one label on the floppy disk.
zConfirm the contents of a floppy disk before formatting it.
Confirm that no important data is on the floppy disk, because all data on the floppy 
disk will be erased.
zUse the write-protect tab (A).
This is a must for preserving important data.
This prevents your data from being erased or overwritten.
zWhen disposing of or transferring ownership of this device, erase all data on the 
hard disk in order to prevent the theft of hard disk data. Even if you delete data or 
initialize the hard disk through normal Windows commands, data can still be read 
using special software. In order to erase all data, either have the data erased by a 
specialist (at a charge) or use the hard disk data erase utility (included) ( Îpage 
33).  (Note that this hard disk data erase utility does not guarantee that data will be 
completely erased.)
Also, note that if you transfer ownership of this device without deleting commercial 
software that you have installed to the hard disk, you may be in violation of the 
licensing agreement for that software.

liquid crystal displays (color LCDs).  Therefore, if 0.002% or less of the picture ele-
ments either fail to light or remain constantly lit (that is, more than 99.998% of ele-
ments are functioning properly), no defect is considered to exist.
