HOW TO USE THIS MANUAL
The manual is divided into several sections. The DIAGNOSTICS section describes self-test and
service diagnostics for checking the system functions. An understanding of the on-board service
capabilities is necessary before any attempt is made to troubleshoot the unit. The
TROUBLESHOOTING section lists error codes and provides troubleshooting guides to assist the
TSR in locating the source of a problem. The REPLACEMENT PROCEDURES section contains
instructions for removal and replacement of the assemblies that are considered field-replaceable.
The ADJUSTMENT AND CALIBRATION PROCEDURES section contains the field procedures
needed to restore original system specifications. The Periodic Manufacturer’s Service (PMS)
PROCEDURE section outlines the steps required to verify the electrical, mechanical and
pneumatic safety of the unit and also identifies components requiring periodic replacement.
GENERAL TROUBLESHOOTING GUIDELINES
Troubleshooting the Narkomed 4 should always begin by communicating withthose who observed
or experienced a problem with the unit. This may eliminate unnecessary troubleshooting steps.
Once a general problem is identified, refer to the troubleshooting flow charts in Section 3 to
determine the proper corrective action to be taken.
After a component has been replaced, verify that the unit is operating properly by running the
appropriate diagnostic procedure. The PMS PROCEDURE in Section 6 must also be performed
after any component has been replaced.
The general arrangement of the Narkomed 4 Anesthesia System is shown on the opposite page.
WARNINGS are used in this manual before procedures which if not performed correctly could
result in personal injury.
CAUTIONS are used in this manual to alert service personnel to the possibility of damage to the
equipment if a procedure is not performed correctly.

NM4 DIAGNOSTICS
2.0 DIAGNOSTICS
The NARKOMED 4 contains a diagnostic system that monitors certain system functions and
records their operational status. A series of tests is performed when the system is powered
up and the results are displayed on the diagnostics screen shown in Figure 2-1. Further
diagnostic functions are available through a series of service screens that can be called up
by a Technical Service Representative at the display panel. The following paragraphs provide
a description of each of the service screens that can be accessed through touch keys on the
display panel. If no display is present upon system power-up, refer to Section 3 of this
manual for troubleshooting assistance.
A PREVENTIVE MAINTENANCE DUE message will appear on the screen if the current
date exceeds the Periodic Manufacturer’s Service due date stored in the machine.

2.4.5 NIBP Monitor Screen
The NIBP Monitor Screen displays Real Time, Systolic, Diastolic and
Mean blood pressure and Pulse.
The TAKE READING touch key will initiate a single NIBP
measurement cycle.
A procedure for checking NIBP cuff inflation pressure against an
external gauge is also displayed, with touch keys to perform the test.
See Figure 2-11.
Refer to Section 6 of this manual for inflation, deflation, and leak
testing procedures.

2.4.6 Gas Analyzer Screen
Current values of CO2,N2O and anesthetic agent are displayed on the
Gas Analyzer Screen along with a span calibration procedure. See
Figure 2-12. (The scrubber bottle replacement instruction is not
displayed on machines having a Model 4610 gas analyzer.)
The MODE window on the gas analyzer screen displays the following
messages: INHIBIT during warm-up
READY after 30 minute warm-up
The STATUS window on the gas analyzer screen displays the following

2.4.7 Line Block Screen
The current sample pressure is displayed on the Line Block screen
along with a calibration procedure and a touch key to enter a setpoint
value. See Figure 2-13. The stored reference value is displayed at the
lower left corner of the screen.
CURRENT SAMPLE PRESSURE: 200
LINE BLOCK CALIBRATION PROCEDURE:
- WITH PATIENT CIRCUIT ENABLED:
- ENSURE THAT SAMPLE LINE IS
CONNECTED AND UNOCCLUDED.
- PLACE A FLOWMETER AT THE SAMPLE
EXHAUST.
- ATTACH FLOW RESTRICTOR, FIX 0336, TO
PATIENT SAMPLE LINE.
- WAIT FOR VALID CURRENT SAMPLE PRESSURE.
- ADJUST RESTRICTION IN ORDER TO
OBTAIN A FLOW OF 100 ML/MIN.
- TOUCH "STORE REFERENCE" KEY.
- FULLY OCCLUDE SAMPLE LINE AND OBSERVE
THAT LINE BLOCK ALARM BECOMES
ACTIVE AFTER AT LEAST 15 SECONDS.
