Yes, you're at v1.00.

Also when you first turn on, or turn off your TX, the version number is displayed in the upper right corner of the screen for about 1 second.

If you haven't already, you need to go to https://www.spektrumrc.com/MyAccount...2fDefault.aspx
and set up a "My Spektrum" account in order to register and update your TX and RX.
