How long do the batteries last

I haven't changed it since I brought it !!! So I hope that helps ? If you buy a good battery they could last for a good 2:years or more

How do you change from Fahrenheit to Celsius?

Hi I am thinking of buying one of these, the installation instructions show DPI switch settings, the bottom section is to adjust F or C , the left is for F and the right for C. It shows you the diagram on the manufactures web site I hope this helps.

how do you remove the dial off?

I presume this is to access the black pairing button. The dial just gently prises straight off the spindle with small screwdriver at right hand side. It is a simple push fit.
