Pairing Bose Wave IV with external device

I have a Hama DAB/FM/Internet tuner which transmits Bluetooth output.  I have successfully paired it with my Bose Wave IV with SoundTouch pedestal and it appears on the Aux input.  The problem is that now whenever I turn the Hama on, the Bose comes on too and plays its output.  I don't want this to happen - I want to choose when to play it on the Bose by selecting it on the Aux input.  How can I stop it doing this automatically?


Bose product name  Wave IV with SoundTouch


Country UK


Firmware Version


App Version


What devices were you using that were affected and what version are they on (e.g. Samsung Galaxy S9 on Android 11, iPhone X on iOS14, etc.) Hama Digital Hifi Tuner DIT2105SBTX

Detailed description of the issue and steps to reproduce  Bose automatically turns on whenever the Hama is turned on.  Can I keep the two paired without this happening?


What environment do you experience the issue in? (e.g. noisy office, quiet kitchen, etc.)


When did you start to experience the issue? Did it work correctly previously?
