Study Notes

Power-On Self-Test (POST)

A 1-second tone signals that the N-560 has powered on successfully and passed the POST.
POST checks circuitry and functions of the N-560 after power-up.
During POST, all display segments illuminate for 2 to 4 seconds, including numeric digits changing from red to green.

Button Press Feedback

Valid button presses trigger a short, medium-pitched tone.
Invalid button presses result in a short, low-pitched tone indicating an inappropriate action.

Alarm System

High Priority Alarm: Fast-pulsating high-pitched tone indicating loss of pulse.
Medium Priority Alarm: Normal-pulsating medium-pitched tone for SpO2 or pulse rate limit breaches.
Low Priority Alarm: Slow-pulsating low-pitched tone for sensor disconnect, low battery, or device failure.
Alarm Silence Reminder: Three beeps approximately every 3 minutes when alarms are silenced.

Pulse Monitoring

A single beep indicates each detected pulse; pitch varies with SpO2 value changes.
Specific tones correlate with pulse rate displayed in various windows (left, center, right).

Device Version Display

After display tests, the N-560 shows the software version for approximately 2 seconds, crucial for technical support queries.

Error Handling

If an internal issue arises during POST, an alarm tone sounds and an Error Code is displayed for troubleshooting purposes.

Guidelines for Use

Absence of the POST pass tone indicates device malfunction; do not use the N-560.
Ensure speaker is unobstructed to hear alarm tones properly; speaker functionality is essential for alerting.

Sensor Operation

While searching for a valid pulse, the N-560 displays dashes in SpO2 and Pulse Rate indicators.
Upon detection of a pulse, the device enters Monitoring Mode, displaying patient parameters and auditory confirmation through pulse beeps.
