To factory reset your Magene Heart rate Monitor:

• Remove the battery cap and battery from the unit.
• Inside the recess, you will see 2 metal connections, 1 below the battery and 1 to the side of the recess.> - Use a paperclip, screwdriver, or any metal object that can bridge the gap between these 2 points. Lightly connect the 2 points and hold for 10 seconds.
