SAFETY - 13
Other Relevant Precautions (cont’d)
• Third Party’s Application Programs
Do not install a third party’s application programs into the PC of the equipment.
Those application programs can be responsible for display of unexpected windows,
adverse effects on the equipment, and interference in the operation of the system
program. Hitachi shall not be liable for the troubles caused by such application
programs.
• Protection against Computer Viruses
Computer viruses are malicious programs that sneak into the PC to cause misbehavior or
damage to data. And, a program designed to offer protection against and eradicate
computer viruses is called a vaccine program.
Virus infection can be caused by using a floppy disk or other storage medium infected by
a virus. Note also that once the PC is infected by a virus, it may spread to other
computers through storage medium. Therefore, never use a program or storage
medium that is suspected of containing a virus.
If there is a possibility of virus infection, check for a virus using a vaccine program. The
user is requested to prepare a proper vaccine program and carry out virus removal on his
or her own responsibility.
Note, however, that some kinds of vaccine programs may cause incorrect operation of
the S-4800 control program. If a problem occurs after you install a vaccine program,
remove it or execute virus check when the S-4800 program is not running. It is desirable
not to set the vaccine program in the auto start-up group, or to terminate the vaccine
program before starting the S-4800 program.
• Do Not Change Computer Settings
Do not change the following system settings of your PC. These are set up at the optimum
conditions for operation of the S-4800 SEM before shipping.
(a) Connection to the USB ports

these are open.
(b) Display screen setting
