S4 Sensor Assembly
The sensor assembly utilizes a magnetic reed switch to detect the rotation of the paddle's sensor disk. Over time, the internal reed switch can suffer from mechanical fatigue or the wiring can develop an open circuit from vibrations during rowing. Replacing the sensor restores the pulse-train signal required by the monitor to calculate speed and distance.

Sensor Disk
The sensor disk is mounted on the upper paddle shaft and contains the magnets that trigger the sensor. If the disk has slipped down the shaft or the magnets have become dislodged, the sensor will not receive the magnetic flux changes necessary to generate a reading. A new disk ensures the proper magnetic field strength and alignment for the tachometer system.

S4 Performance Monitor
If the sensor and disk are confirmed to be functional, the internal logic board of the monitor may have a failed processing chip or a damaged input jack. This prevents the monitor from interpreting the incoming analog pulse-train into digital workout data. Replacing the full assembly is the only way to resolve internal PCB-level signal processing failures.
