Before you begin:


  • Strap your MZ-Switch to your wrist or arm, then press the pulse button until you hear a beep and see the light flash green.

2. Snug is best

  • Make sure the strap is comfortably snug on your wrist, arm, or chest. 
  • On your wrist or arm, you should not be able to see the green LED's against your skin, but it should not be so tight that it restricts blood flow. 
  • On your chest, it should be tight enough that it does not shift with movement, but not to the point of discomfort.

3. Check your battery level

Check your battery at any time on the workout screen on the app. No need to have your belt activated—the app remembers the charge level from the last time it saw your belt. 


If you wear your Switch on your wrist and see it flash orange when you press it on or off, this means you are at 30% battery life. Snap it into its charging cable and plug in to a computer USB or 5v charging block to get fully charged up for next time and avoid data loss. 

4. Keep your chest strap clean

Salt build-up can impede the connection and also cause chafing--make sure you wipe it down thoroughly. The strap can be machine-washed in cold water, but don't put it in the dryer.

Clean around the snaps with an a damp cloth to clear away any salt or soap residue. Do not use anything alcohol-based as that can damage them module.
