My Polar chest strap provides "easy" access to change the battery. The problem is the little indention intended for a coin or screw driver is a bit stripped. I can not get the cover to budge. Are there any tricks for getting it unscrewed?
Thanks,
Gil

Yes, there are a few.
1) As you may noticed, coin and even screwdriver blades are never sharp, but mostly blunt. So, sharpen the edge of the coin on a piece of sandpaper. Get hardened steel screwdriver or very sharp, pointed end file and scrape that indention (groove) to make sure the channel have straight sides, forming I_I shaped groove, but not V shaped groove. When done, insert the sharpened coin and unscrew the battery cover using some pressure as well.
2) In case if the groove is stripped completely, you will have to drill two small holes into the battery cover. Drill them 1mm from the battery cover's edge on opposite sides. Depth of holes should be 0.5 mm. Do not drill through completely. For drilling use 0.3-0.5 mm diameter drill bit.
When finished with both holes, take hardened tweezers, insert each arm into separate hole and unscrew the battery cover.
