The patient monitor will be damaged if the water quantity in the water trap reaches
the limit.
10 The machine will be damaged if any pipeline from the CO
disconnected, or the air tube/air inlet/air outlet has been plugged by water or other
materials.
NOTE:
After the Low battery alarm is activated, please do not start the CO
monitor may be turned off for the low capacity of battery.
