Hi I used to notice the whine on my MSR+ but i dont anymore.

It is there if I hold it to my ear, but you cant hear it in normal use so the question is, What has changed?

It could be worth trying new batteries. (Do it quick so as to preserve any programing you have done)

Is the darkness of the room a factor as I believe it senses this?

In the end, if this is my biggest trouble in life I think I am a very lucky boy!!

Cheers Chris smile
