Have issues with Sony XDR-S61D

[Apache060]

Hello,

I have a  Sony XDR-S61D radio but have the following issues saved the station I want to keep but find that sometimes some of the stations just go off and when I do a scan to find radio stations the Sony XDR-S61D does not find all the stations available. 
I have reset the device but no good.

Any help to fix these issues would be great.

thanks
