SECTION 1
GENERAL USE
If the simulator is cold to the touch or below ambient
temperature, allow it to stabilize before use.
To ensure patient safety, use only parts and accessories
manufactured or recommended by Corometrics Medical
Systems, Inc.
Periodically, and whenever the integrity of the simulator is in
doubt, test all functions.
RESPONSIBILITY OF THE MANUFACTURER
Corometrics Medical Systems, Inc. is responsible for the
effects on safety, reliability, and performance if:
* assembly operations, extensions, readjustments,
modifications, or repairs are carried out by persons
authorized by Corometrics Medical Systems, Inc.;
+ the electrical installation of the relevant room complies
with the requirements of appropriate regulations; and
+ the simulator is used in accordance with the
instructions of use.
DEFINITIONS OF TERMINOLOGY
Five types of special notices are used throughout this manual.
They are: Danger, Warning, Caution, Important, and Note.
The warnings and cautions in this Safety section relate to the
equipment in general and apply to all aspects of the monitor.
Be sure to read the other chapters because there are additional
warnings and cautions which relate to specific features of the
monitor.
When grouped, warnings and cautions are listed
alphabetically and do not imply any order of importance.
Danger
A DANGER notice indicates an imminently hazardous
situation which, if not avoided, will result in death or serious
injury.
Warning
À WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
Caution
À CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate injury.
Cautions are also used to avoid damage to equipment.
important
An IMPORTANT notice indicates an emphasized note. Itis
something you should be particularly aware of; something
not readily apparent.
Note
À NOTE indicates a particular point of information:
something on which to focus your attention.

MONITOR SAFETY INFORMATION
Z\ WARNINGS /\
ACCIDENTAL SPILLS—lIn the event that fluids are
accidentally spilled on the simulator, take the
simulator out of operation and inspect for damage.
ELECTRICAL SHOCK—To reduce the risk of
electrical shock, do not remove simulator cover.
Refer servicing to qualified personnel.
ELECTROMAGNETIC INTERFERENCE—Be
aware that strong electromagnetic fields may
interfere with simulator/monitor operation.
Interference prevents the clear reception of signals
by the monitor. If the hospital is close to a strong
transmitter such as TV, AM or FM radio, police or
fire stations, a HAM radio operator, an airport, or
cellular phone, their signals could be picked up as
signals by the monitor. If you feel interference is
affecting the monitor, contact your Corometrics
Service Representative to check the monitor in your
environment.
ELECTROSURGERY—The simulator is not
designed for use with high-frequency surgical
devices. In addition, measurements may be affected
in the presence of strong electromagnetic sources
such as electrosurgery equipment.
EXPLOSION HAZARD—Do not use this
equipment in the presence of flammable anesthetics
or inside an oxygen tent.
GROUNDING—Do not defeat the three-wire
grounding feature of the power cord by means of
adaptors, plug modifications, or other methods. A
dangerous shock hazard to the operator may result.
PATIENT CONNECTION—Do not connect the
simulator to a monitor that is being used to monitor
a patient.
SECTION 1
A CAUTIONS A
ANNUAL SERVICING—For continued safety and
performance of the monitor, it is recommended that
the calibration, accuracy, and electrical safety of the
monitor be verified on an annual basis by a
Corometrics Service Representative.
CALIBRATION—The Model 325 Simulator is not
a calibration device. It cannot be used to calibrate a
monitor or to compare measurements.
ENVIRONMENT—The performance of the
simulator has not been tested in certain areas, such
as x-ray and imaging suites. The simulator is not
recommended for use in these environments.
PERFORMANCE—Report all problems
experienced with the simulator or monitor under
test. If the simulator or monitor is not working
properly, contact your Corometrics Service
Representative for service. The simulator or
monitor should not be used if it is not working
properly.

INTENDED USES
The Corometrics Model 325 Maternal/Fetal Simulator, shown
in Figure 2-1. provides electronically generated input signals
for ensuring the proper function of a Corometrics Maternal/
Fetal Monitor. It can be used by service personnel to
establish basic monitor functions—it cannot be used to
calibrate or compare measurements. The simulator does not
have sufficient accuracy or repeatability.
The Model 325 Simulator is also helpful in demonstrating the
features of a maternal/fetal monitor.
Signals are provided for verifying the functionality of the
following operating modes:
* FECG (fetal electrocardiograph)
* MECG (maternal electrocardiograph)
+ US or US2 (ultrasound)
+ FMD (fetal movement detection)
* TOCO (tocotransducer)
* IUP (intrauterine pressure)
The simulator is designed to provide signals for the following
monitors:
+ Model 150 Fetal Monitor
e Model 151 Fetal Monitor
* Model 155 Fetal Monitor
e Model 116 Fetal Monitor
« Model 118 Maternal/Fetal Monitor
+ 120 Series Maternal/Fetal Monitor
SECTION 2
FEATURES
The following is a list of the Model 325 Simulator's most
outstanding features:
* Dual heart rate capability for generation of two
different heart rates, simultaneously—US and FECG
or US and MECG.
* Generation of fetal movement detection.
* Rate and level controls for verification of monitor
performance. .
* Internal memory stores 34 minutes of typical heart rate
and uterine activity patterns.
* Line powered for operation without the use of the
Central System connector on the rear panel of the
monitor.
