12.4. Manual Self-test of the Alarm System
You can manually self-test test the alarm system by the following steps:
• Make certain that the SpO
2
alarms on (via the Setup SpO
2
parameter
menu). Attach the SpO
2
sensor to your index finger and wait for the
monitor to display a SpO
2
parameter value. Unplug the sensor from the
PPM3. After 10 seconds, the PPM3 should sound a low grade alarm tone,
flash the SpO
2
parameter box, and display the message "SpO
2
unplugged."
• If the PPM3 is being monitored at the MPC, then disconnect the PPM3
from the communications wall outlet. After 30 seconds, the PPM3 should
sound a low grade alarm tone and display the message "MPC connection
lost."
