Just looked at WM100 in the dark.
The blue light is a good "night light"
But on the left side close to the back, can be seen a red glow.
I have not opened the WM100 yet to see why(what) the light is for.
Mine has worked out of the box without any problems.
Removed all my C15A(s) and AH. Do miss the rolling history.
And the ability to save a log.
Once they come out with a browser, things will change I am sure of that.
thx
