TV is set for video input. Consult your TV manual for reference.

VideoPhone is not functioning properly behind a firewall.
Place the IP address of the VideoPhone in the DMZ of the
firewall. Consult your routers documentation or your network
administrator for help on doing this.
Port forward the appropriate ports to the VideoPhone. The
VideoPhone needs ports 1720 (TCP) and ports 15328-15333
(TCP and UDP) open to function properly. Consult your routers
documentation or your network administrator for help on doing
this.
VideoPhone is not functioning properly behind NAT.
Go to Settings/Network/Public IP. Press Enter on the remote when
the cursor is over “Auto detect public IP Address.” If the
VideoPhone is unable to detect the public IP Address, it should
be entered manually using “Use specific IP Address.” The
VideoPhone’s public IP Address is given to you by either your ISP
or network administrator.
