What to do if my Remak Control Unit shows 'Ab' error?
- EEmily ThomasAug 3, 2025
If the Remak Control Unit displays 'Ab', it indicates a defective battery. This might be due to low capacity. Try charging or replacing the battery. If the signal remains weak after charging, replace the battery, especially if it hasn't been used for an extended period.
