displays a summary list of certificates of the certification authorities that you have set the P-
660HWP-D1 to accept as trusted. The P-660HWP-D1 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.
