Testing with Masimo SET Tester (Optional):

1. Turn the Radical-7 off and then on again.

2. Set the alarm limits to:

% SpO

PULSE RATE

High 100 140

Low 90 50

3. Connect the Masimo SET Tester to the Red Patient Cable Connecter.

4. Verify that within 20 seconds a plethysmographic and a Signal IQ waveform displays.

(may require the Radical-7 to be set to the Pleth and Signal IQ display setting).

5. Verify that the SpO

measurement is between 79% and 84%.

6. Verify that the pulse rate measurement is between 55 bpm and 65 bpm.

7. Verify that an audible alarm occurs and that the SpO

measurement and the low

SpO

alarm are flashing

8. Press the Alarm Silence button once and verify that the alarm is silenced.

9. Wait 120 seconds and verify that the alarm silence times out and the audible alarm

is activated again.

10. Press the Increase Loudness button several times and verify that the loudness of the

pulse beep tone increases.

11. Press the Decrease Loudness button and verify that the loudness of the pulse beep

tone decreases. Press the Decrease Loudness button and verify that the loudness of

the pulse beep tone can be turned off.

Nurse Call Test:

1. Disconnect the Red patient cable or the Masimo SET Tester from the Radical-7 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. 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 measur-

ing data) and verify that the resistance is less than 35 ohms.

Power-On Self-Test:

1. Connect the monitor to AC power and verify that the AC Power Indicator is lit.

2. Turn the monitor on by depressing the Power/Standby Button. Within 5 seconds all

available LEDs are illuminated, a 1-second beep tone sounds, and the Masimo SET

logo is displayed.

3. The blue Docking Indicator LED is illuminated and the Radical-7 begins normal opera-

tion.

Key Press Button Test:

1. With the exception of the Power/Standby Button, press each soft key button and verify

that the Radical-7 acknowledges each key-press with an audible beep tone or by

indicating a change on the display.

Alarm Limit Test:

1. With the monitor turned on, select the Menu Access key and enter the Alarm menu.

Change the High SpO

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 SpO

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 SpO

■ High and Low BPM

■ High and Low SpMet

■ High and Low SpCO

5. Reset the alarm limits again to the original settings.

Display Contrast Test:

1. With the monitor turned on, select the Menu Access key and enter the Display menu.

Change the Contrast parameter by scrolling through the contrast settings.

2. Return the Contrast setting to the original value, or a value that allows maximum view-

ing contrast.

3. Exit the Menu system and press and hold down the Backlight/Contrast button for

several seconds. The display will scroll again through all the contrast settings.

4. Release the Backlight/Contrast button again when the display shows maximum view-

ing contrast.
