When am I entitled to make a warranty claim?
You can make a warranty claim in relation to material and workmanship defects. The warranty does not cover batteries, wear-and-tear parts, wear caused by commercial usage, or accidents. You are only entitled to make a warranty claim if the SIGMA product itself has not been opened without authorization and the receipt of purchase is provided.

How are the magnet and reed switch positioned?
The reed switch housing has 2 protruding points, which mark the sensor area. The magnet must be positioned in relation to the reed switch so that on each wheel revolution, the magnet precisely passes these two protruding points.
How should the magnet be set up?
The magnets provided have a cylindrical shape. The magnetic field is emitted from each end of the cylinder. This area must be aligned with the reed switch’s sensor area.
