INTRODUCTION

Thank you for purchasing the G.LAB MD4120/MD4140/MD4180
Blood Pressure Monitor.
The device is easy-to-use and good for home users and healthcare
professionals. It applies non-invasive oscillometric method which
can measure your blood pressure and pulse rate quickly and easily,
and it saves the data automatically to let you review the average and
measured data at any time.

Indication for use

This device is for use by medical professional or home users. It is
intended to measure the systolic and diastolic blood pressure on an
adult individual by using a non-invasive technique, in which an
inflatable cuff is wrapped around the upper arm.

IMPORTANT NOTES

DO NOT use this device on newborns, infants, children,
toddlers or persons who cannot express their intentions. The
device is designed for use on adults only.

DO NOT self-diagnosis from the measurement results and
start treatment by yourself.

DO NOT adjust medication based on the measurement results.

Consult your physician for specific information about your
blood pressure.

The Irregular Heartbeat detection function may help to detect
potential cardiac arrhythmia at an early stage but it is not
intended to replace cardiac examination.

The “WHO Blood Pressure Classification” chart is a guide for
reference and is not intended to replace medical diagnosis.

Use the device only as intended. Do not use the device for
any other purpose.

Do not apply the device on an arm with an unhealed wound or
under medical treatment.

Do not take measurements more than necessary. High
measurement repetition rates may cause pain, numbness,
temporary red marks or bruising to the arm due to blood flow
interference.

IMPORTANT NOTES

If you have any of the following medical conditions, you may
get an inaccurate reading with the device. Please consult your
physician before using the device.

• Patients in shock

• Cardiac arrhythmias

• Atrial or ventricular premature beats

• Atrial fibrillation

• Arterial sclerosis

• Poor perfusion

• Vessel anomalies

• Very low blood pressure

• Pregnancy

• Diabetes

• Pre-eclampsia

• Renal diseases

• Underwent breast or axillary lymph node removal operation

• With an arteriovenous shunt.

• With an intravenous drip or blood transfusion.

• With implanted electrical device such as cardiac pacemaker

• With other medical electrical equipment attached

• With condition that may compromise circulation

• Severe blood flow problems or blood disorders, as cuff
inflation can cause bruising.

• Trembling or shivering

Do not use the device with other medical electrical equipment
simultaneously.

Do not use the device where high frequency surgical
equipment, magnetic resonance imaging (MRI), computerized
tomography (CT) scanner or X-ray machine is operating.

Do not use the device near electromagnetic fields emission
equipment such as cellular phones, microwave ovens or
televisions.

IMPORTANT NOTES

Do not use the device where flammable gases (e.g. anesthetics
gas, oxygen and hydrogen) or flammable liquids (e.g. alcohol)
are present.

Do not use the device in a moving vehicle such as car or airplane.

Do not use the device outside the specified environment. It may
cause an inaccurate reading.

The product contains small parts that may cause a choking
hazard to infants and children. Keep the device and its parts out
of reach of infants and children.

Do not attempt to open, disassemble, repair, modify or adjust the
device by yourself. It may cause accident, damage the device,
cause inaccurate measurement and void the user warranty.

Do not subject the device to strong knocks (e.g. dropping the
unit on the floor), extreme in temperature, high humidity, direct
sunlight, dust or chemicals. This may damage the device.

The device is not water resistant. Avoid water, rain or sweat from
infiltrating the device.

Clean the device and cuff carefully with a dry, soft cloth or a cloth
dampened with water. Do not use aggressive solvents such as
alcohol, benzene, thinner or other strong chemicals to clean the
device.

Do not fold the cuff tightly for a long period. Such condition may
shorten the life of the part.

Dispose used equipment, parts, batteries and optional
accessories according to applicable local regulations. Unlawful
disposal may cause environmental pollution.

Do not wrap the cuff around body parts other than your upper
left arm. Misuse represents a risk to your health.

Packaging materials are a deadly hazard for children and can
cause suffocation. Remove all packaging materials immediately
and keep them away from children at all times.

Proper cuff size is important for accurate measurements. Only
use the device on adults who have the right

upper arm circumference for this unit. See “TECHNICAL
SPECIFICATION” for suitable arm circumferences.

Batteries should not be charged or reactivated by any other
means. The batteries may explode.

Take extra precaution to keep a leaking battery away from fire as
there is a risk of ignition or explosion.

Do not use any cuffs and accessories other than those explicitly
recommended by the manufacturer for use with this product.
Cuffs and accessories not approved for use with this device may
cause damage to your health and to the product.

The tubing presents a strangulation hazard. Keep this product
away from children and those who require close supervision,

e.g. people with mental disorders.

Do not drape tube around neck. This presents a strangulation
hazard.

Remove any kind of arm jewellery or the like before taking a
measurement. This could cause bruises.

When storing the device, make sure that no heavy objects are
placed on top of it.

IMPORTANT NOTESIMPORTANT NOTES

Do not place the arm cuff over heavy clothing (e.g. a jacket or
sweater sleeve) as the blood pressure monitor will not be able to
take a proper measurement and there is an elevated danger of
acquiring hematoma or skin marks during the course of the
measurement.

In case the cuff does not stop inflating, interrupt the
measurement by pressing the ON/OFF button and open the cuff
at once.

When applying the cuff, make sure there are no wrinkles in the
cuff as this could cause bruises.

Blood pressure measurements can lead to temporary marks on
the skin at the site of the cuff placement. This is especially the
case in high repetition rates, in hypertonic patients and in
patients with weak heart rates. In rare cases a mark may persist
for couple of days. Please contact your physician about these
specific risks of cuff pressure in your specific case.

Do not exert any kind of pressure on the hose during
measurement, e.g. laying your arms or any other object on

the hose. This could cause incorrect measurements.

The device is designed and manufactured for a long service life.
However it is generally recommended to have the monitor
inspected every 2 years to ensure proper functioning and
accuracy. Please contact your dealer for maintenance.

Do not drop or insert any object into any openings or hoses. This
may damage the unit.

Do not press the buttons with excessive force or with pointed
objects.

BATTERY INSTALLATION

1. Remove the battery cover.

2. Remove the used batteries and insert new batteries.
Use LR03 / AAA alkaline batteries.
Make sure the battery polarities (+) and (-) match the markings
on the battery compartment.

3. Close the battery cover.

Battery Level Indicator

symbol on the display indicates that battery level is normal.
When battery level is getting low, symbol and “E6” will appear
on the display. Replace all used batteries with new batteries.

NOTE:

batteries out of the reach of children.

In case battery fluid leaks, do not touch the battery fluid. Avoid
skin contact (e.g. put on protective gloves) and clean the battery
compartment with dry cloth.

Remove the batteries from the battery compartment if the device
will not be used for a long period.

Use only 1.5V alkaline batteries. Do not use other types of
