WRAPPING THE CUFF
1. Place the cu on your left arm with the
air hose positioned toward your hand.
2. Wrap the cu around your arm with the
edge of the cu
approximately 2~3 cm
above the elbow. AIR TUBE should be on
the palm side of the arm.
3. Press the surface of the cu
sure that the hook & loop fastens
securely.
When wrapping the cu , wrap it loosely
enough around the arm so that two
ngers can be placed between the cu
and the arm. If the cu
more tightly or loosely than this,
inaccurate blood pressure readings may
result.
If you are wearing a shirt that might
restrict circulation in your upper arm
or you roll your sleeve up over the
upper arm, the blood
restricted,
preventing
measurement.

Take deep breaths and relax.
Do not move, chat or strain
your arm or hand during
measurement.
To stop measurement
Press POWER BUTTON and in ation stops, air is
exhausted, and monitor turns o .
If the pressure applied is judged insu cient in the early phase
of measurement or if movement of the hand or wrist occurs
during measurement, the unit will in ate again to a level
about 40 mmHg higher. Automatic Repressurization is
repeated until a measurement is made. However, this does not
indicate a problem.
To manually control pressurization, hold down POWER
BUTTON immediately a er the start of in ation and release
it when the pressure reaches the level 50 mmHg higher than
the expected maximum systolic pressure. If the pressure value
ashes when pulse
has exceeded 180 mmHg, the in ation will stop when the key is
detected
during
released. Pressure can be increased to approximately 300 mmHg.
A ashing heart mark in
the measurement result
display indicates irregular
e result is
pulse rhythm.
Irregular pulse rhythm can be a result of body movement
during measurement or arrhythmias. Although continuous
appearance of the indication under quiet measurements may
suggest arrhythmias, do not make any judgment on your
own before consulting with your doctor.
Do not execute repeated measurements for
congestion of blood could result in false
measurement. Let your arm rest for at least 5
minutes.
