Turn off smart antenna

Can someone tell me how to turn off the smart antenna in an ePmP2000. I assembled and tested a radio with the smart antenna, but when I deployed it, it went to a different tower site than originally planned, so I rempved the antenna for re-use. The home screen says 

Smart Antenna Smart Antenna is Disconnected, Power On

I cant see anywhere to turn it off. 

Hi,

Smart Antenna cannot be turned off.
It can be connected or disconnected physically.
You can configure Forced Sector Antenna with the latest firmware installed.
And only Sector Antenna will be used.

Thank you.
