FortiAP Region Settings

Hi All, 

I have a client with some older FortiAP 221B's in the environment. In the FortiAP profile on the Gate the region is set to ZA, which works for all other models connected to their firewall here in South Africa, but these ones are complaining about region mismatch. 

If I get direct SSH access to the APs, and run fap-get-status, I see that Regcode is N. Assuming this is region code, this would be E for our country code. 

Does anyone know how I can check the actual country configured on the AP, and how to set this or the region code?
