You can check the firmware version you are running. I think you access it through the config or settings menu, then select "about". If it is 1.0-en### then you are probably running hardware version 1.0. The only way to tell for sure is to update your firmware to the 1.02-en version. With the newer firmware it will display your hardware version.

And yes the bind issue is a drawback for the WP receiver boxes. A few have said the receiver will go into bind mode if it doesn't get a signal after 30 seconds. Waiting that amount of time and then enabling the bind on the transmitter seems like a viable work around though I haven't tested it.
