CLEANING METHOD OF CUFF

After cleaning the cuff with a neutral detergent, lightly rinse it
with water and let it dry in the air.  Hard rubbing or washing in a

washing machine will cause air leakage.  Also, be careful not to
get water into the air hose.

GENERAL REMARKS

General Remarks on blood pressure measurement

If the cuff is to be deflated quickly, depress “POWER” switch.

The attached cuff is suited for an arm circumstance of 22cm
to 32cm.

When attaching the cuff, rubber cuff hose should be placed
on the inside of your arm on top of the arterial.

Self measurement is no therapy! In no case may you change
the dosage of medication prescribed by your physician.

In operation for blood pressure measurement, you should
urinate and should remain relatively still for 10 to 15 min-
utes prior to measurement.

Exercise, eating and drinking, smoking, etc., prior to mea-
surement may affect the results.

The blood pressure varies constantly throughout the day.
Measurement should be made regularly at the same time
each day.

Do NOT be impressed by the results of one measurement.
Keep a record of blood pressure variations. Many readings
tell a story.

Emotional stress may tend to cause pressure to rise.

For proper measurement of blood pressure

Take a deep breath five or six time and then relax before
measuring blood pressure.  If you are tense when taking
the measurement, you will not get a valid reading.
