Pinch the ends of the finger sensor to open the sensor to its widest point.
5.
After the monitoring system completes POST, verify the finger sensor LED is brightly lit.
6.
Allow the sensor clip to close slowly.
7.
Verify the LED intensity decreases as the LED approaches the optical sensor.
8.
Open the sensor again and verify that the LED intensity increases.

instructions for use.
If not already done, press and hold the Power On/Off button to turn the monitoring system on and
2.
verify the monitoring system is operating.
The monitoring system should stabilize on the subject's physiological signal in about 15 to 30 seconds.
3.
Verify the oxygen saturation and pulse rate values are reasonable for the subject.
Alarms and Alarm Silenced
Access these settings from the Service Menu by using the pass code provided by Technical
Services. Reference
