3 Safety Warnings
ALWAYS follow the statements below as they are essential to reducing
the risk of use error due to ergonomic features of the device or the
environment in which the device is intended to be used.
Only trained personnel who have read, understand and agree to follow the
Instructions for Use should operate the device.
Retain the Instructions for Use for future reference.
Refer service needs to trained authorized personnel. Failure to do so may
cause the device to fail and void the warranty.
Inspect the device and accessories before operating and ensure: (a) there
is no evidence of physical damage; (b) the sensor (particularly the sensing
surface) and electrical connections are dry; and, (c) the sensor is installed
and is upstream from any humidifying device for accurate calibration and
oxygen readings.
Calibrate: (a) with a known source of dry air or 100% oxygen before using
each day or after 8 hours of continuous use; (b) when the temperature or
pressure of the operating environment changes; (c) if the oxygen sensor
has been disconnected and reconnected; (d) after the battery or oxygen
sensor has been replaced.
Sampling flowing gas: (a) install the optional accessories as shown in Sec-
tion 8.1 and (b) assure there is a tight fit between the components.
Sampling static, ambient or controlled atmospheres unscrew and remove
all components from the oxygen sensor.
Clean the device and accessories in accordance with Section 6.1.2 .
Battery replacement Section 6.2: (a) replace the batteries when the ‘LO’
message is displayed on the LCD and (b) calibrate the analyzer after re-
placing the batteries.
Oxygen sensor installation or replacement Section 6.3 or 6.5: allow the
new sensor to stabilize for 15-20 minutes in ambient air before attempting
to calibrate.
Store the device by turning the power OFF and removing the batteries if
the device will not be operated for over thirty (30) days.
Attempt to repeat the procedure that caused a perceived malfunction and
refer to troubleshooting hints in Section 7 before concluding the device is
faulty. If in doubt, contact the manufacturer for assistance.

NEVER operate the device in any manner described below doing so
may compromise the clinical condition or the safety of patients, users
or other persons.
If the reading is unstable or a malfunction is suspected.
After the ‘ERR’ or ‘LO’ messages are displayed on the LCD.
Near equipment capable of emitting high levels of electromagnetic radia-
tion (EMI) or radio frequency interference (RFI).
Expose the device; particularly the LCD display or sensor to sources of
extreme heat, cold or excessive sunlight beyond the device’s storage
temperature range, refer to Section 8 for extended periods of time.
In a gas stream with a vacuum greater than 14” water column.
Immerse the device, oxygen sensor or optional coiled cable in any liquid.
Outside of the parameters specified in Section 8 particularly at flow rates
greater than 10 liters per minute - the backpressure generated produces
erroneously high oxygen readings.
Calibrate: (a) with 20.9% oxygen or room air with the intent of taking
oxygen measurements at oxygen levels above 30% oxygen; (b) in a
humidified gas stream or atmosphere; (c) without allowing a newly in-
stalled sensor to stabilize for 15-20 minutes in ambient air.
Attempt to sterilize, autoclave, liquid sterilize, immerse in any liquid or
expose the device or accessories to steam, ethylene oxide or radiation
sterilization.
Open the main compartment of the device, except to change the integral
oxygen sensor.
Open the oxygen sensor or probe the sensing surface, refer to Section 10
in the event the sensor should leak and someone comes in contact with
the electrolyte from inside the sensor.
Optional remote sensor with a cable that appears worn, torn or cracked,
or, allow an excess length of cable near the patient’s head or neck; se-
cure it to the bed rail or other suitable object to avoid the possibility of
strangulation.
Allow the device or oxygen sensor to be serviced, repaired or altered by
anyone except trained personnel – failure to do so may endanger the
patient or damage the device rendering the warranty null and void.
