Is there way of manually setting IP address in DM800

I am having problem with DM800 can't get IP address by holding down the button is there way of manually setting up the IP address??

Try Setup > System > network > adapter settings deselct DHCP and then type in the ip address you want to use for your dm800. You will also need to set the gateway for your router and DNS enteries for your ISP.

Many thanks I will try this and post feed back
