Note

●If you do not make a list, access is permitted to all hosts.

●If the list provided prohibits access for all hosts, the Host Restriction function is disabled and access is permitted to all hosts.

●To prohibit access over HTTP connection via a proxy server, the address of the proxy server must be set.

●If you set the host restriction incorrectly, access to the settings page itself may be denied. In this event, the problem can only be recovered by restoring the factory default settings.
