Chapter 13 Certificates

P-660HWP-Dx User’s Guide

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.
