1Introduction
This handbook explains how to install, use, maintain and clean the fetal maternal monitor.
To ensure the safet of the patients，this apparatus must be used
under the supervision of a doctor or a nurse.
In case of failure, the technical staff of breakdown service will occur
b telephone or repairs will be ensured on site b us or the s stem
will be turned over for repair, according to the opinion of our
compan
Not to use the equipment in place where anaesthetic gauzes or
other flammable substances are placed.
The user must make sure that the material is in good condition
before using it.
When the equipment is used, certain electromagnetic radiation
ma be produced, which ma interfere the electronic equipment
or device nearb . The potential of jamming would be reduced to
a great extent when the electronic equipment or device is far
awa from the equipment.
Please ensure the devices connected with the monitor form an
equipotential bod (ensure effective connection).
The discarded materials must be treated in accordance with the
regulations on the management of these products to prevent the
pollution of the environment. Directl contact the manufacturer
for the technical questions.
To make sure that all the lines of connection use, the hoses or
pipes are far from the neck of the patient.
Although the majorit of the components used received tests of
biocompatibilit , the can involve an anaph laxis at certain
individuals.

- 2 -
To ensure the safet and the curative effect of a patient, use the
accessories recommended b the manufacturer. If not, the patient
can be wounded or curative effects can be reduced.
If a portable monitor falls accidentall it is not more available for
the use, ou must supervise its results attentivel , to continue to
use the monitor that when the results of measurements in
conformit with the standard.
A bad application can lead to the erroneous data acquisition, so
ou must work according to the procedures described in the
handbook of corrective measurements to ensure of the results.
Not to use the equipment in room of imager (such as CT or IRM).
If ou use the monitor and the sensor when the equipment of
imager is used, it can cause currents induced on the sensor
connected with the patient and cause potential wounds. The
monitor can influence the function of the equipment of imager
and the equipment of imager can influence the exactitude of
measurements of ox gen of the hemoglobin and other parameters
of the monitor.

4S fety
Configuration of the monitor conforms to the international requirements of safet for
medical electrical appliance, such as IEC60601-1, IEC60601-2-37, IEC60601-1-2,
IEC60601-1-4, IEC60601-1-8 and IEC60601-1-8.
4.1Environment requirement
To guarantee the absolute safet of the electric environment, installation of the equipment
should reasonabl avoid jolts, dust, corrosive installation or gas explosion, of the extreme
temperatures and moisture, etc. At the time of the installation of the equipment in wall
mount, leave sufficient space for the operation. If the door is open, make sure there is a
sufficient space behind the equipment to facilitate maintenance. Ensure good ventilation
inside the cabinet.
If the monitor functions at a temperature of 5 ℃ ~ 40 ℃, it can meet the technical
requirements index. If the temperature exceeds the range, it will affect the precision of the
monitor and the components and circuits.
Environment of work
Operating temperature: 5 ℃ ~ 40 ℃
Relative humidit : ≤ 80%
Atmospheric pressure: 80kPa ~ 110 kPa;
Tr nsport tion nd stor ge:
Temperature: -20 ℃ ~ 50 ℃
Relative humidit : ≤ 93%
Pressure 60kPa atmospheric ~ 110.0kPa;
Do not connect several monitors when using, otherwise it ma
cause cumulative leakage which ma raise risk of electric shock to
the patient or the operator. In case of doubt, to contact the
supplier.
To leave at least 2 cm (or 5 inches) of the device to ensure an
adequate ventilation.
Keep the device far from the direct light of the sun; Not to store in
a place with over high/low air pressure, or when the temperature
and moisture are higher than the standards or ventilation is bad,
or in a place with accumulated dust, or with sulphur, salt, gas and
other chemicals. Tr to avoid the contact of water. The apparatus
must be managed and stored according to the standard
specification

4.2Grounding Monitor
To protect the patients and the medical personnel, the monitor must be grounded. For this
reason, the monitor is equipped with a detachable triplex cable, and is grounded via the
ground wire (protective ground) of power line once the cable is inserted into the match
three-pin socket.
If there are no three pins, please consult electrician of the hospital.
Connect the ground wire to the equipotential ground terminal of device. If ou are not sure
whether a special device combination has risk or not according to the specifications, for
example an accumulation of leakage current would lead to a risk, ou should consult the
relevant manufacturer or other experts of this field to ensure the safet of this device is
not damaged b the suggested combination.
4.3Equipotenti l Ground
For the first class of the protection of the device, it is realized b grounding the attaching
plug, which is included in the s stem of earthing of protection of the house. For the
internal audit of heart, the device should be individuall connected to the equipotential
s stem. One end of the equipotential grounding wire (potential equalization conductor) is
connected to the equipotential grounding terminal at the rear panel of device, and the
other end is connected to the other connector of the equipotential s stem. If protective
grounding s stem is damaged, the equipotential grounding s stem could take on the safet
