Due to compliance reasons any model that has been certified for "thin" mode (where it talks to a controller) cannot be moved to standalone mode. The FCC certifications are done on the exact model number so any changes to the model type is not supported unless the unit is stamped standalone to begin with (example: sticker will say 3630/3640).
