Upon trying my new (old stock) Polar RR K4 circa 2011 via Legacy it had no sound and the cab light blinked in intervals of 3-blinks. The instructions say that is a diagnostic code indicating a smoke unit problem. I re-programmed and reset per the instructions but still no-smoke and the cab light still blinks 3-times. The whistle smoke works fine.
I left the engine alone and came back and tried it again today. Again, no sounds but this time it did NOT give the 3-cab light blinks - and, the main smoke unit made a loud whine. Am not sure why it would give the 3-blink diagnostic code one day and not the other?
So, I re-programmed again, and the sounds came up full volume, and the smoke unit started smoking! But, the whine is still there - loud enough to make it annoying and it almost drowns out the engine sounds!
Anyone know if this whine will go away over time?
