Does anyone own one of these alarms? (http://cgi.ebay.com/Compustar-CM1000...QQcmdZViewItem)

Don't get me wrong, it's a sweet system and I'm very happy with it, but the manual is written horribly. It doesn't even explain the features of the product. So, that's why I am going to ask you...

1. What does Valet Mode do?

2. If a light impact is detected, does the siren "chirp" like the Viper models do?

3. If you select one of the options on the back of the remote, how do you know if these options are activated? Like how do you know if you just turned the shock sensor on or off, does the siren chirp or something?
