Polar S720i: altitude & temperature readings

I have found every now and then my S720i gives inaccurate altitude & temperature readings- it would appear it happens when it is very hot. Anyone have similar experience and is there something that can be done to fix it?

 

I don't know whether its relevant but I do a lot of swimming in a salt water pool- maybe this can affect it.Confused

If you use the watch on your arm the temperature will be way off. Always mount it on the handlebars.

 

 

 

Even if you have set the altitude, it is still different from day to day because the unit uses temperature and air pressure to get a ball park figure.

They can't do everything. The temp and altitude readings are reasonably accurate and are not meant to be accurate to a fraction of a degree or to a foot. I suppose they could make it more accurate but then you would pay much more for "secondary" functions.
