3. Real Fuzzy Measuring Technology
This unit uses the oscillometric method to detect your blood pressure. Be-
forethecuffstartsinating,thedevicewillestablishabaselinecuffpressure
equivalenttotheairpressure.Thisunitwilldeterminetheappropriate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 pres-
sure, diastolic blood pressure, and pulse.

5. Blood Pressure Standard
The National High Blood Pressure Educa-
tion Program Coordinating Committee has
developed a blood pressure standard, clas-
sifying blood pressure ranges into 4 stages.
(Ref. The Seventh Report of the Joint Na-
tional Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood
Pressure-Complete Report JNC-7, 2004).
This blood pressure classication are
based on historical data, and may not be
directly applicable to any particular patient.
It is important that you consult with your
physician regularly. Your physician will tell
you your normal blood pressure range as
well as the point at which you will be con-
sidered at risk before making any health-
care decision based on the device’s read-
ings.
For reliable monitoring and reference of
blood pressure, keeping long- term re-
cords is recommended. Please download
the blood pressure log (chart for recording
and tracking crucial info: date, time, blood
pressure, pulse rate and body condition) at
www.rossmaxhealth.com.

3. 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 ( ) over the main artery
(on the inside of your arm). (Fig. 3,4)
Note: Locate the main artery by pressing
with2ngersapproximately2cm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.
4. Plug in the cuff connecting tube into the unit. (Fig. 5)
5. Lay your arm on a table (palm upward) so the cuff is at the same height as
your heart. Make sure the tube is not kinked (Fig. 6).
6. This cuff is suitable for your use if the arrow
falls within the solid color line as shown on
the right (Fig. 7). If the arrow falls outside the
solid color line, you will need a cuff with other
circumferences. Contact your local dealer for
additional size cuffs.

9. Measurement Procedures
Important Notes:
Here are a few helpful tips to help you obtain more accurate readings:
• Bloodpressurechangeswitheveryheartbeatandisinconstantuctuation
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 15 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.
