Arc 7 HD proximity sensor?

Does the Arc 7 HD have a proximity sensor?

Picked one up as a Christmas gift for my girlfriend, but the sleep cover for the Arc is terribly cheap, not to mention overpriced. I'd like to buy a 3rd party cover that just relies on the sensor that's in most other Android tablets.

Thanks for a head's up on this.

EDIT: Answered my own question. Apparently not. :(
Returning it and buying another Asus.
