pulse rate tone decreases.

10. Set QRS volume to Off and return to the monitoring screen. Verify beeping pulse rate

tone is no longer audible.

11. Return QRS volume to a comfortable level.

Sensor LED Test

This procedure uses normal system components to test circuit operation. An SpO

sensor,

DS-100A is 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

extension cable to the monitor.

4. Connect the SpO

sensor to the SpO

extension cable.

5. Leave the sensor open with the LEDs and photodetector visible.

6. After the monitor completes its normal power-up sequence, verify that the sensor LED

is brightly lit.

7. Slowly move the sensor LED in proximity of the photodetector element of the sensor

(close the sensor slowly). Verify as the LED approaches the optical sensor, 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 the 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.
