Does ios -- rcvk9w8 needs to be changed into k9w8 ?

Hi From the output of command "show flash" in AS 1400, we can see its ios is rcbk9w8. I checked it in internet where it is said as following. I am not sure if the ios is used directly. It mentioned that it lacks radio firmware. How to solve the issue? Any one can give a suggestion ? Thank you.

rcvk9w8 – lightweight recovery image – this is factory installed on lightweight APs, unless a “mesh” image is specified; it lacks radio firmware

The rcvk9w8 image is overwritten once the AP joins the WLC.  A proper version of code without the rcv part of the file is downloaded automatically to the AP when it joins for the first time, then it reloads using the proper image.
