What size battery- I tried the 1620 it is to big?

I have used the CR2032 lithium 3V battery.

How do you keep the Tempo Trainer near your ear when running? Do they attach to sunglasses or sweatvac visors?

it has a clip to attach to a hat/visor, not glasses.

I ordered mine a few weeks ago. Battery it came with never worked. I bought a new CR 1620 and tried 1632 and still does not work. What can I do?

I never had and still haven't had any problems with my Tempo Trainer.If yours isn't working,I would send it back and get a new one.My works fine.
