The phone has no connection to the Internet.

Check the cable connection between the base station and the router (the LED on the

base station must light up) and the connection between the router and the Internet con-

nection.

Check whether the phone is connected to the LAN.
– It may not have been possible to dynamically assign an IP address to the phone
or
– You have assigned a static IP address to the phone that has either already been

assigned to another LAN subscriber or does not belong to the router's address block.

Press the paging key on the base station. The IP address appears on the handset dis-

play.

Press the talk key on the handset to end paging call.

Start the Web configurator with the IP address.

If no connection can be established, change the settings on the router (activate DHCP

server) or the phone's IP address.
