Dapol 64/74xx factory sound - which cv to turn down that repeating noise...

[seeseerider]

Hi all,

 

For anyone who has the factory fitted sound version of the 6409/7400 class - you know that automatic periodically repeating coal shoveling + injector sound? What cv can I set to turn it down - or preferably off. It’s so loud as delivered and much too frequent.

 

Thanks.
