Flat-lining is the only indication of a light change at the measurement site. If the
monitoring system recovers and displays normally, this is an indication of proper
operation with light changes.
a.
Active visual and audio alarms.
b.
Saturation indication between 73 and 77 inclusive.
c.
BPM indication between 57 and 63 inclusive.
d.
Pulse waveform of approximately half-inch P-T-P amplitude. Actual amplitude
may vary but references low modulation/low light indications.
23.
Turn off the monitoring system by pressing the POWER ON key.

Setting Nurse Call
To set and verify the nurse call function:
1.
Ensure the monitoring system is connected to an AC power source.
2.
Connect a DOC-10 interface cable to the sensor port.
3.
Locate the DB-15 connector on the side of the monitoring system.
4.
Review the DB-15 pinouts. Reference DB-15 Pin Layout , p. 7-5.
5.
Ensure the audible alarm is set to at least 50%. Reference To configure alarm
volume , p. 10-19.
6.
Connect the negative lead of a voltmeter to pin 5 and positive lead to pin 11.
7.
Connect the SRC-MAX to the DOC-10 interface cable.
8.
Turn on the monitoring system by pressing the POWER ON key.
9.
Verify an output voltage at pins 5 and 11 b5 to +12 VDC.
10.
Press ALARM SILENCE. With the audible alarm silenced, the output voltage at pins
5 and 11 must be between -5 to -12 VDC.
11.
Simulate an alarm condition using the RS-232 Nurse Call function.
12.
Use a digital voltmeter (DVM) to ensure there is no continuity (1 megohms or
greater) between pins 8 and 15 and there is continuity (60 ohms or less) between
pins 7 and 15.
