09/27/22: Just unpacked and installed my two PRR Heavy Pacific's 20-3818-1 & 20-3819-1 and like the SRR 20-3820-1 I can not get the whistle smoke to function. I depress the two soft keys SPW & FSW both will high light and the word Whistle comes up in the display but no whistle smoke the 3820-1 will give me a quill able whistle but not able to get the 3818-1 or 3819-1 to work.All three of my remotes do the same thing so I know it has to be something that I am doing wrong. HELP AGAIN!!!
