13.9 Trusted CAs

Click Security > Certificates > Trusted CAs to open the Trusted CAs screen. This screen

displays a summary list of certificates of the certification authorities that you have set the P-

660HWP-Dx to accept as trusted. The P-660HWP-Dx accepts any valid certificate signed by a

certification authority on this list as being trustworthy; thus you do not need to import any

certificate that is signed by one of these certification authorities.
