How do you change the battery?

Although the unit is designed NOT to have the battery replaced, it can be done. It takes a CR2032 coin type battery.I followed this video and successfully replaced mine in under ten minutes.https://youtu.be/lBsv9XoV6aA

Is it compatible with a life fitness treadmill? If so how can it be connected?

Yes it is compatible, actually I purchased for same treadmill brand . It is conected automatically by gymlink so no setup is required. Great product .

how do you pair this t31 with compatible treadmill machines with polar sign on it?

Pairing is automatic. Just start your workout and it will sync with a little sweat

Does the t31 work with the iphone 5? I've tried without success using both MapMyRide and the Polar App. Cheers M

The problem is that you need the device to be capable of acquiring data from the transmiter in it's own frequency and I do not think that the iphone is able to do that without a special additional device. For example you have a app called sports tracker that has its own heart rate monitor, I do not know how it works gut there must be some way to catch the information from the heart rate monitor to the phone. For what I know is very probable that you should need some additional device to get the heart rate monitor frequency.
