Hey all you fitness people out there my dad tried to change the battery in his polar A3 and now it doesn't work he brought it to me with a couple extra pieces and said here fix it please... i would but i have no idea how it is supposed to back together does anyone have this or a similair model? and can you see how the battery is captured in the back of the recieving unit (the watch looking thing)
these 2 pieces have me stumped.
thanks for any help guys/gals
