3. Verifying Operation

CAUTION

• The 920 must be able to measure the

pulse properly to obtain accurate SpO

measurement. Verify that nothing is

hindering the pulse measurement

before relying on the SpO

measurement.

Verify that the sensor is properly positioned. Ensure the system is

sensing adequate perfusion by observing that the (perfusion)

indicator is blinking green, and the blinking is correlated to the pulse

rate for 10 seconds. Should the perfusion light be red or yellow or

flashing erratically, reposition the sensor or try a different sensor.

4. Cleaning the Pulse Oximeter

CAUTION

• Do not immerse the 920 in liquid to

clean.

• Do not use caustic or abrasive

cleaning agents.

The 920 Pulse Oximeter may be cleaned with a mild detergent and

a soft cloth or with an isopropyl alcohol wipe. Allow enough time for

the 920 to dry thoroughly before reusing.
