What does 'CO2 COMM ERROR' mean on ZOLL M Series Medical Equipment?
- DDarryl HillSep 1, 2025
If the ZOLL Medical Equipment shows 'CO2 COMM ERROR', it means there's no communication from the EtCO module or sensor. Turn the M Series unit off, then on again to reset it. If the problem continues, the unit may require servicing.
