Hitachi S-4800 manual Third Party’s Application Programs, Protection against Computer Viruses

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.
