**VERIFYING FILES**
CHECK CERTIFICATE
(FILENAME.CRT)
**AUTHENTIC**
or
--- FAILED ---
When the download is complete, the terminal restarts
automatically. The file authentication module on the
receiving terminal begins to check for new certificate
(*.crt) and signature (*.p7s) files included in the
download. These special files then process one at a time;
certificates process first, then signature files.
When the file authentication module is invoked, the status
display informs you of the progress of the file
authentication process. If file authentication succeeds for a
specific certificate, the “
AUTHENTIC” message is displayed
directly below the certificate filename. If file authentication
fails for a specific certificate, the “
FAILED” message is
displayed for five seconds below the filename and the
terminal beeps three times, allowing you to note which
certificate failed to authenticate.
The authentication process then continues to the next
certificate until all new certificates are authenticated.
