• When installing a certificate, make sure the projector supports
its format.
s "List of supported certificates" p.126
• You can also install digital certificates on the projector from a
USB storage device. However, if you install a certificate from
both a USB storage device and the network, it may not be
installed correctly.
Secure HTTP Notes
When Secure HTTP in Administrator Settings from the Network menu is
set to On, security using HTTPS protocol is automatically applied. You can
use this function to increase security between the projector and a Web
browser.
A certificate is used in communication using HTTPS protocol to certify
reliability of the server. Create a server certificate to verify reliability from a
Web browser, and install it on the projector.
If there is no server certificate, the projector automatically creates a self-
signed certificate and communicates. Because this self-signed certificate
cannot verify reliability from a Web browser, a warning about the server's
reliability is generated when the projector is accessed from a Web browser.
Although the security level is decreased when compared to a server
certificate, you can continue to communicate by ignoring the warning.
