7960 IP Phone probs - 'Settings' no available

I need to access a 7960, which was for a year powered off.

Firmware and tftp server are ready. I did a factory reset.

The phone tries to get an IP, but fails.

The problem: I can't access the 'settings' button.

If I press 'Settings' or '**#' and then 'Settings' nothing happen. The
phone simply doesn't react somehow.

Any ideas, how I may configure the phone after a factory reset and how
to reach 'Settings'?
