It's very easy to use. Run the program, and the screen will be off. But the PDA is still working. It's useful to play music like mp3.

To turn on the screen again, push the power button.

Update Description:
v1.1:
- The about dialog box is closed before turning off.

I already had it on my MDA compact. I've put it again on my new phone. It works very well, and it's saving power while litening to music or radio.
