Service / Maintenance

Performance Verification

To test the performance of the Radical-7 Pulse CO-Oximeter following repairs or during routine

maintenance, follow the procedure outlined in this section. If the Radical-7 Pulse CO-Oximeter

fails any of the described tests, discontinue its use and correct the problem before returning the

instrument back to the user.

Before performing the following tests place the Radical-7 Pulse CO-Oximeter Handheld into the

Docking Station, connect the Radical-7 to AC power and fully charge the Radical-7 Pulse CO-Oximeter

Handheld battery. Also disconnect any patient cables or pulse oximetry probes, as well as SatShare,

serial or analog output cables from the instrument. Set the Radical-7 Pulse CO-Oximeter to normal

operating mode by selecting the Home Use parameter in the General Menu to “No”.

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 operation.

Key Press Button Test:

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.

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.

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

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

Display Contrast Test:

Change the Contrast parameter by scrolling through the contrast settings.

Return the Contrast setting to the original value, or a value that allows maximum viewing contrast.
