Manual Filzer dB4LW Cycling Computer
Janice 27-09-2022
My cycle computer was working as designed until a week ago. It has stopped displaying my speed, though all other displays work. New batteries, verified transmitter is with 2mm clearance from magnet. Another issue. The unit is now shutting off within 5 seconds of stopping. Thoughts?
