Getting started

If you cannot establish communication by setting DHCP On, you need to set up an IP Address
manually and a Subnet Mask if necessary. To do this, follow these steps:

Display the Ethernet
Network Settings menu
and select DHCP Off.

Push the IP Address
bezel button to enter an
IP address. You need
to contact your network
administrator to get the IP
address to use.

Push the Subnet Mask
bezel button to enter a
Subnet Mask. Ask your
network administrator
whether a subnet mask is
required.

Push the Default Gateway
bezel button to enter
a gateway address.
Ask your network
administrator for the
gateway address.
