On the WPU only, if the Agents option is run over a continuous 12 hour period with an O2
concentration of 22% or greater there is a Warning Box that will appear to alert the operator that a
one (1) minute O2 Calibration sequence must be run. The Warning Box will offer the operator a
Yes/No option of running the one (1) minute O2 Calibration sequence, if the operator selects NO,
the message will reappear in 30 minutes. An O2 Calibration message will also appear if the O2
Sensor detects a reading greater than 103% and whenever an O2 sensor is inserted into the back of
the monitor (if the monitor has completed its CO2 zeroing process).
a. Anesthetic Agent Quality Control (QC) Check. Perform a QC Check at least once a
month, or whenever Agent accuracy is questionable.
(1) Before performing the Anesthetic Agent QC Check, the monitor must be at a
stable operating temperature. The monitor must be turned on, with EtCO2 and
Agent parameters active, for a minimum of 45 minutes before the QC check is
performed.
(2) Each QC Check Gas can comes with a nozzle and tubing with a “T” fitting for
connecting to the gas (EtCO2) input port in the monitors front panel.
(3) See the Accessories List in the Table of Contents Section of this manual for
selection of the QC Check Gas for the Anesthetic Agents you are using.
(4) If required, Agent Span Calibration can be performed. Refer to service
instructions for this procedure.

gases (including halogenated agents and nitrous oxide) is not recommended. Always attach the
waste gas connection on the rear of the monitor to the room's gas evacuation system. Avoid venting
any waste anesthetic gas directly into the room air as exposure to waste anesthetic gases above the
recommended OHSA limits could result.
Flashing Insp CO2 Numeric (Fixed CO2 Rebreathing Alarm) The Inspired CO2
numeric turns red and flashes with Alarm sound. Occurs
when Inspired CO2 is greater than 25 mmHg. This
alarm is a fixed, non-adjustable alarm.
Flashing N2O Numeric (Fixed N2O Alarm) N2O numeric turns red and flashes
with Alarm sound. Occurs when N2O is greater than
80%. This alarm is a fixed, non-adjustable alarm.
EtCO2 WARMING UP Message flashing red. Occurs during CO2/Anesthesia
Gas Sensor warmup.
CO2 OCCLUSION Message flashing red with Alarm sound. Occurs when
sample line is occluded.
