Real Fuzzy Measuring Technology
This unit uses the oscillometric method to detect your blood pressure.
Before the cuff starts inating, the device will establish a baseline cuff
pressure equivalent to the air pressure. This unit will determine the ap-
propriate ination level based on pressure oscillations, followed by cuff
deation.
During the deation, the device will detect the amplitude and slope
of the pressure oscillations and thereby determine for you the systolic
blood pressure, diastolic blood pressure, and pulse.

3. Place the cuff over the bare up-
per arm, wrap it with the tube
pointing your palm, and the artery
mark over your main artery.
4. The edge of the cuff should be
at approximately 1.5 to 2.5 cm
above the inner side of the elbow
joint. If the index line falls within
the range of the arm circumfer-
ence indicator, the cuff circum-
ference is suitable, otherwise you
may need a cuff with a different
circumference.
5. Center the tube over the middle
of the arm. Press the hook and
loop material together securely.
Allow room for 2 ngers to t
between the cuff and your arm.
Position the artery mark (Ø) over
the main artery (on the inside of
your arm).
Note: Locate the main artery by
pressing with 2 ngers approxi-
mately 2 cm above the bend of
your elbow on the inside of your
left arm. Identify where the pulse
can be felt the strongest. This is
your main artery.
6. Lay your arm on a table (palm up-
ward) so the cuff is at the same
height as your heart. Make sure
the tube is not kinked.

Measurement Procedures
Here are a few helpful tips to help you obtain more accurate readings:
• Blood pressure changes with every heartbeat and is in constant uc-
tuation throughout the day.
• Blood pressure recording can be affected by the position of the user,
his or her physiological condition and other factors. For greatest
accuracy, wait one hour after exercising, bathing, eating, drinking
beverages with alcohol or caffeine, or smoking to measure blood
pressure.
• Before measurement, it’s suggested that you sit quietly for at least
5 minutes as measurement taken during a relaxed state will have
greater accuracy. You should not be physically tired or exhausted
while taking a measurement.
• Do not take measurements if you are under stress or tension.
• During measurement, do not talk or move your arm or hand muscles.
• Take your blood pressure at normal body temperature. If you are
feeling cold or hot, wait a while before taking a measurement.
• If the monitor is stored at very low temperature (near freezing), have
it placed at a warm location for at least one hour before using it.
• Wait 5 minutes before taking the next measurement.
1. Press the ON/OFF key. All digits will light up, checking the display
functions. The checking procedure will be completed in 2 seconds.
2. After all symbols appear, the display will show a blinking “0”. The
monitor is ready to measure.
3. Auto Mode
• In Auto mode, mark appears on the display.
• Press the START key, the monitor will automatically inate the cuff
slowly to start measurement.
• When the measurement is completed, the cuff will exhaust the
pressure inside. Systolic pressure, diastolic pressure and pulse will
be shown simultaneously on the LCD screen. The measurement is
then automatically stored into memory zone.
