Nigel, I have now checked CV265 and it’s set to 101, CV310 is 1, 311 is 0 hope they’re correct
I can can confirm that the United was purchased as being with sound and all appears to be wired up correctly, I have spoken to Dapol and they referred me to Hattons who can only refund my money as they can’t replace it! But I think it’s worth keeping it as it’s still good value and cheaper than a DCC fitted one. At the moment I am just trying to find a solution and still have other leads to follow so thanks for helping it’s much appreciated.
regards Mike
