• Wait 5 minutes between successive measurements.
• The measurements you make yourself are only for your information
– they are no substitute for a medical examination! Discuss your
readings with your doctor and on no account make your own
medical decisions (e.g. drugs and their dosages).
• The wrist measurement will be less accurate if an arm suffers from
restricted blood circulation resulting from chronic or acute vascular
diseases (including vasoconstrictions). In this case, use a sphyg-
momanometer for measurements on the upper arm.
• Measuring errors can occur in diseases of the cardiovascular
system, as well as with very low blood pressure, irregular blood cir-
culation and arrhythmia and also in the case of other symptoms.
The blood pressure computer consists of precision-made electronic
components. The measuring accuracy and life of the computer
depend on the care with which it is treated:
- Protect the computer from shocks and be careful not to drop it,
- Protect it against moisture, dirt, wide fluctuations in temperature
and the direct rays of the sun,
- Do not use it in areas where there are strong electromagnetic
fields, i.e. keep it away from transmitters and mobile phones.
• Do not press buttons without the cuff fitted.
• Use the computer only on persons for whose wrist size the compu-
ter is intended.
