I had a rear speaker receiver for my ST300 stop working. Contacted Bose who said they don’t have stock of the single receiver. So into eBay where I got a replacement.
I am struggling to get both the old working on and new replacement to pair. Old working takes about 10s to display the orange LED but remains solid. New replacement orange LED comes on immediately. In pair mode on the ST300 eventually old working goes white however new replacement just stays orange with then ST300 failing to pair.
I've reset the ST300 a few times and on/off the power on receiver with little success.
