MEMO:
Execution of the following may delete the keys/
certificates used for encrypted communications
and the CA certificates used for authentication of
external server certificates:
- replacement/formatting of the HDD
- replacement of the main controller PCB/initial-
ization of the RAM
If a key/certificate for encrypted communications
has been deleted, the control panel screen will in-
dicate a message to the effect that the key has
been corrupted: however, the key/certificate/CA
certificate installed at time of shipment from the
factory may be
brought back by executing the following: COPI-
ER>FUNCTION>CLEAR>CA-KEY. If doing
so has failed, use the SST to install the key/certif-
icate/CA certificate, and execute CA-KEY once
again.

Item CA-KEY
If the user has generated/added a key/certificate/
CA certificate on his/her own, executing CA-
KEY will also delete these files. Inform the user
of this, and ask him/her to re-install them as nec-
essary after the execution of CA-KEY.
