Hi there !!!!!
SETI will automatically try to dial out whenever it needs a new work unit, at the same time it will send it's results...
Your machine should do around 3 WU/day.....
To stop it dialling out 3 times a day you can use SETIQ which will download a few days worth of WUs and store them for you. You can set it to upload/download at a particular time.....
Check out one of our websites...
There's loads of info on how to Tweak SETI, setup SETIQ etc...

If you need anymore help, keep them questions coming...
cheers,
