When you change the battery in the watch for your Timex Bodylink system -- note the orientation of the metal plate on the back of the watch. You must remove four tiny Phillips head screws to remove this plate to get to the battery.
After replacing the battery, PUT THE METAL BACK PLATE ON THE WATCH IN THE SAME ORIENTATION IT WAS WHEN YOU REMOVED IT. If you don't do this, the beep function on the watch will not work -- not a button beep, not an alarm, not an hourly chime, nothing, the watch won't make a sound.

I know.
Okay here's another: The Timex HRM sending unit has a user-replaceable battery. On mine, there is a little tiny reset button right beside the battery - a tiny brass-looking spot that needs to be depressed after the battery is in place. If for any reason the battery jiggles up as the cover is replaced, re-seat the battery and re-press the reset button.
