WARNING
If the gas supply from the endoscopic CO
2
regulation unit cannot be stopped by
pressing the start/stop switch, stop the gas supply by turning the valve of the CO
2
gas cylinder clockwise.
CAUTION
Be sure to stop the gas supply from the endoscopic CO
2
regulation unit before
disconnecting any gas tubes, water container, endoscope, or lens cleaning sheath.
As the gas supply is not designed to automatically stop when disconnection takes
place, replacing the endoscope without stopping the gas flow will not only empty
the CO
2
gas cylinder but may also increase the CO
2
concentration in the
environment.
NOTE
When the endoscopic CO
2
regulation unit is combined with the Gas tube
(MAJ-1741), the Low flow gas tube (MAJ-1742), or Extra low flow gas tube
(MAJ-1816), the gas flow rate is approximately equivalent to that when the airflow
pressure level setting of the light source is set to “High”, “Medium”, and “Low”. For
the standard gas flow rate with different types of endoscopes, refer to the
endoscope’s instruction manual.
