1. Introduction

1.1. Features of the WW1YB-3

The blood-pressure monitor WW1YB-3 (with integrated time/date display) is a fully automatic, digi-
tal blood-pressure measuring device for use on the wrist, which enables very fast and reliable
measurement of the systolic and diastolic blood-pressure as well as the pulse frequency by way of
the oscillometric method of measuring. The device offers a very high and clinical tested measure-
ment accuracy and has been designed to provide a maximum of user-friendliness.
Before using, please read through this instruction manual carefully and then keep it in a safe
place. For further questions on the subject of blood-pressure and its measurement, please con-
tact your doctor.
Attention!

1.2. Important information about self-measurement

• Do not forget: self-measurement means control, not diagnosis or treatment. Unusual values
must always be discussed with your doctor. Under no circumstances should you alter the
dosages of any drugs prescribed by your doctor.
• The pulse display is not suitable for checking the frequency of heart pacemakers!
• In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument
should only be evaluated after consultation with the doctor.

Electromagnetic interference:

The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong
electrical or electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones,
microwave cookers). These can lead to temporary impairment of the measuring accuracy.

2. Important information on the subject of blood-pressure and its measurement

2.1. How does high/low blood-pressure arise?

The level of blood-pressure is determined in a part of the brain, the so-called circulatory centre,
and adapted to the respective situation by way of feedback via the nervous system.
To adjust the blood-pressure, the strength and frequency of the heart (Pulse), as well as the
width of circulatory blood vessels is altered. The latter is effected by way of fine muscles in the
blood-vessel walls.
