If the sensor is unresponsive (no LEDs)...
Before first use --
- Wake the sensor for first use by connecting the sensor to its charging cable and a power source. Then moisten the skin contact pads and install snugly on your chest, centered on the base of your sternum, below your pectoral muscles.
Any other time --
- Moisten the skin contact pads and install snugly on your chest, centered on the base of your sternum, below your pectoral muscles.
- If unresolved, connect the sensor to its charging cable and a power source.
- If unresolved, gently clean the contacts of the sensor and sensor-end of the charging cable with isopropyl (rubbing) alcohol and fully dry them before trying again.
- If unresolved, try another confirmed functional power source (charging block).
- If unresolved, try another compatible charging cable.

If you aren't seeing heart rate data in your app / on your GPS cycling computer...
- Moisten the skin contact pads and ensure the sensor is installed snugly on your chest, centered on the base of your sternum, below your pectoral muscles.
-
Confirm the sensor has an LED response to being installed. If not, see
If the sensor is unresponsive (no LEDs)... -
If the unit is responsive, ensure that your TRACKR HEART RATE is paired to the app / GPS cycling computer you are using and (if your app / computer allows data source selection, like in the Wahoo app),
select the TRACKR HEART RATE as the source for heart rate data for that activity's profile.
-
Also, check for a firmware update. See
Update Firmware on Wahoo sensors.
- If unresolved, delete and re-pair the sensor to your app or GPS cycling computer.
- If unresolved, try turning off your cycling computer or phone and in the process, toggling off your bluetooth for more than 10 seconds using your phone's system bluetooth settings.

- Please note, if the sensor's LEDs are functioning, it will be broadcasting heart rate data, and so this will be an app or phone settings issue.
