If you are trying to teach a new Polar s3 stride sensor W.I.N.D / Polar s3+ stride sensor or Polar G3 GPS sensor W.I.N.D. to your Polar RS800 Running Computer, and "Sensor Not Found" is displayed, possible reasons are that
- Stride sensor / G3 GPS sensor has already been taught to your RS800 Running Computer.*
- Stride sensor / G3 GPS sensor has run out of battery.
*) When purchasing stride sensor / G3 GPS sensor as an accessory, teach the sensor to the RS800.
When you use the RS800/RS800sd/RS800G3 for the first time, it has already been taught to work together with the Polar WearLink W.I.N.D. transmitter and s3 stride sensor / G3 GPS sensor to measure heart rate, speed/pace, and distance data. Also, there is no need to teach teach the sensor after replacing sensor batteries.
If teaching the sensor fails, go to Settings → Features → S sensor → Remove all to remove all stride sensors / G3 GPS sensors from the monitor before trying again. This action will not remove the WearLink transmitter.
