General Safety Precautions
The following are general safety precautions that apply during servicing of the equipment
covered by this manual. These precautions are repeated elsewhere in this manual where
needed.
WARNINGS indicate conditions or practices which if not strictly observed could result in
personal injury.
CAUTIONS indicate conditions or practices which if not strictly observed or remedied could
result in damage to the equipment.
WARNING: Ensure that AC power is removed from the machine before removing the power
supply. Failure to observe this precaution may cause injury by electric shock.
WARNING: Possible explosive hazard if used in the presence of flammable anesthetics.
CAUTION: The flow tube must be properly centered over the guide rings or damage to the
flow tube may occur.
CAUTION: Do not over-tighten the retainer. Over-tightening the retainer may break the
flowmeter tube.
CAUTION: The controller circuit board contains static sensitive devices. Use ESD
protection when handling the controller assembly. Static discharge can damage
components on the circuit board.
CAUTION: The processor board contains static sensitive devices. Use ESD protection
when handling the processor assembly. Static discharge can damage
components on the circuit board.
CAUTION: Observe wiring colors and polarity markings to ensure that the battery is
connected correctly. Connecting the battery with reversed polarity may damage
the circuitry.
CAUTION: Always operate machine on level surface. Before moving the machine, remove
vaporizer, remove items from top shelf and display arm, secure absorber
against left side of machine.

1.0 Introduction
1.1 Purpose
This manual provides the information needed to field service and maintain the
Narkomed Mobile anesthesia system. 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 shows the electrical distribution scheme 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 Certification (PMC) PROCEDURE section outlines the steps required
to verify the electrical, mechanical and pneumatic safety of the unit and also identifies
components requiring periodic replacement.
1.2 Recommendations
Because of the sophisticated nature of Draeger Medical, Inc. anesthesia equipment
and its critical importance in the operating room setting, it is highly recommended
that only appropriately trained and experienced professionals be permitted to service
and maintain this equipment. Please contact DrägerServiceSM at [phone] for
service of this equipment.
Draeger Medical, Inc. also recommends that its anesthesia equipment be serviced at
three-month intervals. Periodic Manufacturer's Service Agreements are available for
equipment manufactured by Draeger Medical, Inc.. For further information
concerning these agreements, please contact us at [phone].

1.3 General Troubleshooting Guidelines
Troubleshooting the Narkomed Mobile should always begin by communicating with
those 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 PMC PROCEDURE in Section 6
must also be performed after any component has been replaced.

DIAGNOSTICS
NM MOBILE
2.0 Diagnostics
The Narkomed Mobile contains a diagnostic system that monitors certain system functions
and records their operational status. Following a brief System Startup display at power up,
the diagnostics screen shown in Figure 2-1 appears. This display includes one of three
messages at the completion of the diagnostics
FUNCTIONAL: This message indicates that the Narkomed Mobile has passed all power-up
tests and is fully functional. The machine will proceed to the MACHINE MONITOR screen
after a short delay.
CONDITIONALLY FUNCTIONAL: This message indicates that a minor problem has been
detected. The screen will retain this display until any key is pressed, then the MACHINE
MONITOR screen will be displayed.
NON-FUNCTIONAL: this message indicates that a serious problem has been detected. The
machine will not proceed into the MACHINE MONITOR or SYSTEM MONITOR screen.
The 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.
Further diagnostic functions are available through service screens that can be called up at
the display panel. The following paragraphs provide a description of each service screen that
can be accessed at the display. If no display is present upon system power-up, refer to
Section 3 of this manual for troubleshooting assistance.
