Q7000 Sub reacts to Mobiles

Hi guys,

I have a new setup Onkyo TX-NR616 with the Q7000 speakers... Man is it good!

But a quick question, my Sub reacts badly (as in not shielded) to mobile signals.

Is there any way I can calm this down?

As sometimes even if my phone is in the other room, the sub will make a sound.

Obviously doesnt happen if the sub is off.

Is it normal for it to react so much? My last sub didnt have this issue.
