and correctly as well as to prevent the risk of damage to you and others.

• The icons and meanings are shown as follows.

Warning sign

Contents

Indicates matters in which bodily harm or material damage* may arise as a
result of incorrect handling.

Examples of signs

Self-diagnosis of measured results and treatment are dangerous. Please follow the
instructions of your doctor.

• Self-diagnosis may worsen the disease.

• When the arterial sclerosis proceeds due to diabetics, hyperlipemia, or hyperten-

sion, it may cause peripheral circulatory disturbance. For these cases, blood pres­sure may differ greatly between measurement at the wrist and the brachial.

Do not use this monitor for the infant or the person who cannot express one's inten­tion.

• They may suffer accident or trouble.

Do not use this monitor for purposes other than measuring blood pressure.

Notes on Safety

Important instructions for obtaining meaningful readings

Avoid eating and drinking (alcohol), smoking, sport and taking medicines before measuring your
blood pressure as this could affect your blood pressure level.

Before you start sit comfortably on a chair and relax. It is recommended to check your blood pressure
at least twice a day, in the morning after getting up and in the evening after work, or as advised by
your doctor.

Do not move and do not speak while the measurement is being taken. Avoid measuring your blood
pressure while you are in a moving vehicle.

Allow an interval of at least three minutes between readings. Otherwise congestion of blood might
occur and distort the readings. Always remove the cuff between readings.

Bare your wrist and take of your watch and jewellery before applying the cuff. Do not constrict the
flow of your blood if you push up your sleeve.

Cautions

Blood pressure measurement is not suitable in case of serious arteriosclerosis (hardening of the
arteries).

The pulse rate indicator is not suitable for monitoring the frequency of cardiac pacemakers.
If you suffer from disorders of heart rhythm, known as arrythmia, you should only use this blood pres-

sure monitor in consultation with your doctor. In certain cases oscillometric measurement methods
can produce incorrect readings.

Pregnant women should only measure their own blood pressure in consultation with their doctor since
the readings may be changed by the pregnancy.

Please remember: Self-measurement is not the same as medical treatment!

You should never

change the dose of medicines as prescribed by your doctor!
Before using your OMRON 637IT for the first time

Your blood pressure monitor: the benefits

The OMRON 637IT is a compact fully automatic wrist blood pressure monitor. Operating on the oscil­lometric principle it measures your blood pressure and pulse rate comfortable and quickly from the
wrist. It contains an intelligent system for “fuzzy” controlled inflation, known as “Intellisense”. This is
an advanced method of oscillometric measurement. No pre-setting of re-inflation is necessary.

The OMRON 637IT has a Position Sensor. The Position Sensor is able to determine the optimal
height of your wrist (heart level) for the blood pressure measurement. Measuring at the heart level is
extremely important since measuring at a higher or lower position will give wrong results.

The OMRON 637IT has a large DOT matrix display enabling you to enlarge the digits and showing
you graphs. Together with the USB computer interface and the built in alarm function for same time
measurements or pill intake your OMRON 637IT is the optimal device to manage your blood pres­sure.
