"Q: Are there different versions of ACCESS receivers and transmitters for different regions? new
A:
There are no different versions of ACCESS receivers, but the transmitters do have separate modes (LBT and Non-LBT modes). The ACCESS receiver will automatically recognize the working mode according to the transmitter when they are communicating. The LBT mode only works in the EU. Users in the US and other places can choose either mode to use."
