returns to .

NOTE

z The touchscreen function does not work in the Setup Utility.

Operation of the touchscreen

z Operate the touchscreen with your finger or with an approved stylus

When using the touchscreen function, use only your finger or an approved stylus on the surface. Operating the touchscreen with an object other than your fingertip or the stylus (a fingernail or metal object, or other hard or sharp objects that may leave a mark) may scar or stain the surface, causing the touchscreen to malfunction.

z Do not apply too much pressure when operating the touchscreen

Only a light touch is required to operate the touchscreen. Applying too much pressure may damage the surface.

Maintaining the performance of the touchscreen

z When the touchscreen becomes dirty, wipe it with a soft cloth

The touchscreen is specially treated to prevent dirt from adhering to the surface, so dirt can be removed easily using a dry cloth. If the dirt does not come off easily, breathe on the surface and try again. Do not apply water or solvents to the soft cloth.

z Clean the touchscreen while the computer is powered off

Cleaning the screen while the power is on may cause the computer to malfunction. Also, dirt on the touchscreen is easier to see when the computer is powered off, and so is easier to clean.

z Wash the soft cloth when it becomes dirty

When the soft cloth becomes dirty, wash it with mild detergent. Do not use bleach or fabric conditioner (softener), or try to sterilize the cloth by boiling. If the soft cloth is dirty, it may be ineffective in cleaning the touchscreen, and in fact may cause dirt to adhere to the touchscreen.

Touchscreen

z Check the following to prevent the surface of the touchscreen from being scratched

z Are you using your finger or a stylus to operate the touchscreen? z Is the surface clean? z Is the soft cloth clean? z Are you using the stylus with the tip extended? z Is the tip of the stylus clean? z Is your finger clean?

Things to keep in mind when using the touchscreen

z Do not touch the screen outside of the LCD display area

The touchscreen input area is defined by the LCD display screen. Touching the screen outside of the display area may result malfunctions or damage to the touchscreen.

z Do not apply excessive force to the touchscreen

Do not lift the computer while holding the LCD screen, or allow the screen to be twisted. Do not place any objects on the LCD screen. Any of the above may cause the touchscreen glass to break, or may damage the LCD screen.

z Operation response may be slower in low temperature environments

The touchscreen may respond to operations more slowly when using the computer in temperatures less than 5°C, but this is not a malfunction. Response time will return to normal when the computer is returned to room temperature.

z If the cursor jumps to a location other than where the screen was touched, or if the LCD reso-

lution changes, recalibrate the touchscreen

Perform the procedure of “Touchscreen Calibration” (Î page 10).

Security Measures

Preventing Your Computer from Unauthorized Use

You can set a start-up password to protect your computer from unauthorized use.

1 Set the password (Î page 21), and select [Enabled] in [Password on Boot] in the [Secu-

rity] menu of the Setup Utility (Î page 64).

NOTE

z If the Supervisor Password or User Password has been set, the password input screen will be displayed on starting-up

of the Setup Utility even though [Password on Boot] is set to [Disabled].

Preventing Your Flash Memory Data from Being Read or Written

The flash memory lock function protects the flash memory data from being read or written when the flash memory is attached to another computer. The data can be read/written when the flash memory is returned to the original computer.

1 Select [Enabled] in [Hard Disk Lock] in the [Security] menu of the Setup Utility (Î page

64).

CAUTION

z For the data being read/written on the original computer, the Setup Utility settings must be the same as when the flash

memory was removed.

z You cannot use the flash memory lock function without setting the Supervisor Password. Set the Supervisor Password

beforehand (Î page 21).

z When you have your flash memory drive repaired

• Contact Panasonic Technical Support.

• Before sending back the flash memory drive, be sure to set the [Hard Disk Lock] to [Disabled].

NOTE

z The flash memory lock function works with the built-in flash memory. It does not work with the external hard disk. z We recommend you to set [Password on boot] to [Enabled] to ensure security though it is not required to enable the

flash memory lock. (Note that the flash memory lock does not guarantee complete protection of the data.)

Battery Power

High temperature mode

The high temperature mode can prevent the battery from deteriorating when the computer is used in high-temperature environment or used for a long time with its battery fully charged. Select [Auto] (default) or [High Temperature] in [Environment] of the [Main] menu of the Setup Utility (Î page 61).

NOTE

z Note that a level corresponding to a 100% charge for high temperature mode is approximately equivalent to an 80%

charge level for normal temperature mode.

z After switching from [Normal Temperature] to [High Temperature] or vice versa, the remaining battery capacity will not

be displayed correctly until the battery pack is completely discharged or fully charged.

z In the [Auto] mode:

Once the computer has automatically switched from the normal temperature mode to the high temperature mode, the computer will not switch back to the normal temperature mode until the battery has been used and recharged to a total charge level of about 5 times as much as that of the fully-charged state. This is to avoid battery deterioration. In [Auto] mode, mode switching is possible only for the battery pack in operation. The other battery’s [Environment] mode remains the same.
