What to do if DEFA DVS90 system is not responding?
- DDaniel WilliamsJul 27, 2025
If your DEFA Car Alarm system is not responding, it might be due to a defective alarm fuse or a drained vehicle battery. Try replacing the broken fuse with a new one and charging the car battery. You can use a DEFA MultiCharger 1204 for charging.
