- Remove HRM from bra! Although it is sweat resistant, it is not waterproof. Immersing the HRM in water will void the warranty.
- Machine wash on cold, drip dry.
- Do not bleach, tumble dry, or iron.
- Insert coin under the lip on the battery door and press in a quick downward motion until the battery door pops off.
- Ensure replacement battery polarity is identical (negative side must face circuit board).
- Press battery door firmly until it snaps into place.
The Mi Pulse HRM uses a CR2032 button cell battery
