For the Mavic Air 2, there is no "CE" model. The aircraft will go into CE or FCC mode depending upon where you are flying. If you bring yours to the US, it will use FCC transmission. If I bring mine to the UK, it will use CE.
The poster I was replying to though he may have purchased the wrong model. He/she did not.
