What to do if ZOLL Aed Plus shows a red 'X' or beeps when off?
- MmurphyrobinSep 5, 2025
If your ZOLL Medical Equipment is showing a red “X” in the status indicator window or making a beeping noise when the unit is off, you should: 1. Perform a manual test. 2. Check that the cable is properly attached to the unit. 3. Replace the batteries. If the unit still does not operate correctly after these steps, remove it from service.
