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.

  Connection to the USB ports 
This instrument uses a USB port for communication between the PC and the 
internal microprocessor. The USB port number 1 is occupied for the instrument.
