Can anyone provide insight as to the method and/or CV(s) that require editing to eliminate the automated default whistle and bell settings. I want to execute the whistle and bell when I desire and not when the default settings say it should be executed.  I have scoured docs on both Soundtraxx and Bachmann FAQ's and forums, only to come up empty.  I did find all the default CV settings for this model but do not see a setting for the automated default.   Model is a C&O # 84801.
