I have a bose lifestyle system with 3 zones, including 2 running audio speakers from sa amps. the main system and one of the audio systems work fine but the 3rd zone i cannot get a signal from the media centre. the remote has new batteries and when i have it right next to the lifestyle base it registers that other rooms are on then shuts down straight away. can anyone help?
