You can configure a 'Rest-of-World' Instant AP to any country code. If I'm correct all ETSI domains (I tested NL, The Netherlands), allow channels 100-140 on 5 GHz.
For legal reasons the Instant AP's sold in or to the US, Israel (IL) or Japan (JP), are locked to those country settings and cannot be changed. The type of AP can be seen in the product serial number: IAP-205-RW is a Rest-of-World AP; for some older AP's like the RAP-109, the product without addition of -US, -IL or -JP, so just RAP-109, is a Rest-of-World AP.
As a warning, setting the AP to another country than you are in, violates regulations and may result into legal action against you. You should not set this to another country, also for the reason that some devices sense the country code from SSID beacons that they hear, and refuse to connect to the channels in your local regulatory domain. So this may result in connection problems for your production WLAN.
