Ultra - How to automatically disconnect my iphone bluetooth when WIIM turned off?

[midnightlightning]

I often connect my iphone to the WIIM Ultra using bluetooth to listen to radio. If I then turn the Wiim off and go into another room and try and listen to the radio on my iphone the Wiim turns back on.

This is very annoying, I realise if I manually disconnect the iphone bluetooth each time it solves the issue but is there a better way - perhaps a Wiim setting to stop the iphone turning the Wiim on when I play music?
