Setting Access Restrictions
Important
• To prohibit access via a proxy server in HTTP connection, a proxy server address must be set.
• If host access restriction is set mistakenly, access to the Setting Pages themselves may be prohibited, in which case restoring the
factory default settings will become the only means of recovery.
The following settings can be configured here.
