These functions prevent theft, tampering, wrongful operation, illegal execution, etc. of a customer's assets saved on a 
personal computer or in modules in the FX5 system as a result of illegal access by a third party. Use of the security functions 
according to the following purposes.

Precautions

When a personal computer registered with a security key is misused by a third party, the outflow of program assets cannot be 
prevented. For this reason, the customer must adopt sufficient measures as explained below:
 • Personal computer antitheft measures (using a wire lock, etc.)
 • Management of personal computer users (deletion of unwanted accounts, strict control of login information, introduction of 

fingerprint authentication, etc.)

Also, when a personal computer registered with a security key malfunctions, locked project data cannot be accessed/viewed 
or edited. Mitsubishi Electric Corporation cannot be held responsible for any loss that may occur as a result of this with the 
customer, other individuals or organizations. For this reason, the customer must adopt sufficient measures as explained 
below:
 • Export registered security keys and import them into another personal computer.
 • Store files containing exported security keys in a safe location.
