1.
With the monitor turned on, select the Menu Access key and enter the Alarm menu.
Change the High SpO2 Alarm parameter to a value two points below the currently selected
value, and accept the change.
2.
Verify that the newly set parameter is shown on the Saturation Alarm Limit Display, next to
the SpO2 or pulse rate measurement display.
3.
Return the High Saturation Alarm parameter to its original setting.
4.
Repeat steps 1 to 3 for the following alarm parameters:
■
Low
SpO2
■
High and Low Pulse Rate
■
High and Low Respiration Rate (RRa)
■
High
SpMet
■
High
SpCO
■
High and Low SpHb
■
PI
■
PVI
5.
Reset the alarm limits again to the original settings.
Testing with Masimo SET Tester (Optional):
1.
Turn the Radical-7R off and then on again.
2.
Connect the Masimo SET Tester to the Pulse CO-Oximeter Patient Cable Connector. Refer
to the Masimo SET Tester's Directions for Use for further instructions.
Nurse Call Test:
1.
Disconnect the Red patient cable or the Masimo SET Tester from the Radical-7R and turn
the instrument on. Ensure that there are no audible alarms and that the audible alarms are
not silenced. Verify the nurse call polarity is set to normal (default).
2.
Connect the common lead of a digital multi-meter to the pin 12 (Nurse Call - Common)
of the analog output connector on the Radical-7R. Connect the positive lead of the multi-
meter to pin 6 (Nurse Call - Normally Open) of the analog output connector and measure
that the resistance is greater than 1 MW (open circuit).
3.
Trigger an alarm on the monitor (e.g. by disconnecting a sensor after it was measuring
data) and verify that the resistance is less than 35 ohms.
Analog Output Test
1.
Disconnect all patient cables and sensors from the Radical-7R. Turn the Radical-7R
off and then on again.
2.
Connect the common lead of a digital voltmeter to the pin 2 (Ground) of the analog
output connector on the Radical-7R Connect the positive lead of the voltmeter to pin
9 (Analog 1) of the analog output connector.
3.
Enter the menu system and set the “Output”, “Analog 1” to “0V Signal”. Verify that the
voltmeter measures a voltage of approximately 0V.
4.
Enter the menu system and set the “Output”, “Analog 1” to “1V Signal”. Verify that the
voltmeter measures a voltage of approximately 1.0V.
5.
Repeat Steps 3 and 4, with the positive lead of the voltmeter connected to pin 15
(Analog 2).
