3970 help

I have purchased a HP 3970 and have never used one before. I am trying to teach muself how to use it but have no instructions. When I turn on the radio on from the bottom right of the screen what does this do?
What do I need to connect to the internet? I have a wireless router at home.
How can I put videos on to watch? What format do they need to be in?
Basically I know very little but have no documentation to assist me.
Can anyone help?

In anticipation - Thank You

Welcome to our forums.
The radio is Bluetooth, this allows you to connect to things like mobile phones and GPS receivers.
You will either need a modem for the iPAQ or a Wifi card.
Video formats depend on what program you want to watch them in. The iPAQ has windows mobile which supports a limited number of formats.

The internet is a huge resource for pocketpc related information.
