Why is the alarm on my Schumacher XI75DU?
- D
  Daniel StoneJul 27, 2025
  The alarm on your Schumacher Media Converter may be triggered by several factors: * A short circuit or excessive surge power demand from the connected device. Try cycling the converter power OFF and then ON. * A low 12-volt battery. Recharge or replace the battery. * An excessively high 12-volt voltage. Try cycling the converter power OFF and then ON. * The connected device requiring more power than the converter's continuous power rating. Consider using a larger converter or a smaller device. * The converter overheating. Improve ventilation, move it to a cooler location, or reduce the power consumption of the connected device.
