11. Set HR/PR tone volume to “Off” and return to the monitoring screen. Verify beeping
pulse rate tone is no longer audible.
12. Return HR/PR tone volume to a comfortable level.
Sensor LED Excitation Test
This procedure uses normal system components to test circuit operation. A DS ‐ 100A ,
used to examine LED intensity control. The red LED is used to verify intensity
modulation caused by the LED intensity control circuit.
1. Connect the monitor to an AC power source.
2. Press the Power button to turn on the monitor.
3. Connect the SpO
2
extension cable to the monitor.
4. Connect SpO
2
sensor to the SpO
2
extension cable.
5. Leave the sensor open with the LEDs and photo detector visible.
6. After monitor completes its normal power ‐ up sequence, verify that the sensor LED is
brightly lit.
7. Slowly move sensor LED in proximity of photodetector element of the sensor (close
the sensor slowly). Verify; as LED approaches the optical sensor, that the LED
intensity decreases.
8. Open the sensor and notice that the LED intensity increases.
9. Repeat step 7 and intensity will again decrease. This variation is an indication that the
microprocessor is in proper control of LED intensity.
10. Press Power button to turn off the monitor.
Restoring Power ‐ On Default Settings
The following test procedures will verify that alarms are activated at the level of factory
default alarm limits and that any changed settings are saved and in effect when the user
changes alarm limit settings and saves the current settings as a power default.
