Do you have Troubleshooting for CS and S-series Cadence Sensors?
The CS and S-series sensors are wireless, so it is very important to mount the sensors as specified in the user manual.
If you have the sensor mounted within the factory specifications and you are experiencing “drop outs” or no cadence readings, it may be due to one of the following reasons:
Settings in the Polar cycling computer:
The cadence option should be turned on. If you are not using the Polar Power Output Sensor make sure you have the Power option turned off. Please refer to the user manual for instructions.
Outside the wireless range:
The cadence sensor range is 80cm/2’6” for both the S-series and CS cadence sensors. If you are outside that range, please refer to the user manual for setup instructions.
Once the above two issues have been ruled out. The below troubleshooting may help further.
Remove the watch/cycling computer from the bike mount and spin the crank. Hold the computer within 1 inch of the sensor.
Does the computer register cadence now? If so, slowly move the computer away from the sensor to determine the range. Some materials used in bicycle frames may dampen the wireless signal.
If not – Does the LED light blink on the sensor(S-series only)? How long have you owned the sensor? The battery may be low.
Make sure the sensor is tight on the fork and does not move around. The magnet should also be very tight.
If the computer registers very abnormal readings during the ride, the issue may be due to Electromagnetic interference. Sources could be from high voltage power lines, traffic lights, overhead lines or railways.
