1. Introduction
3. Real Fuzzy Measuring Technology
4. Preliminary Remarks
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
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 pressure, diastolic blood pressure, and pulse.
This Blood Pressure Monitor complies with the European regulations
and bears the CE mark “CE 0366”. The quality of the device has been
veried and conforms to the provisions of the EC council directive
93/42/EEC (Medical Device Directive), Annex I essential requirements
and applied harmonized standards.

7. Display Explanations
The National High Blood Pressure Education Program Coor-
dinating Committee has developed a blood pressure standard,
classifying blood pressure ranges into 4 stages. (Ref. The Seventh
Report of the Joint National Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood
Pressure-Complete Report JNC-7, 2004).
This blood pressure classification 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 considered at risk.
For reliable monitoring and reference of
blood pressure, keeping long- term re-
cords is recommended. Please download
the blood pressure log at
www.rossmaxhealth.com.
Blood pressure uctu-
ates all the time!
You should not be overly
worried if you encoun-
tered two or three meas-
urements at high levels.
Blood pressure changes
over the month and even
throughout the day. It is
also inuenced by season
and temperature.

Here are a few helpful tips to help you obtain more accurate readings:
• Blood pressure changes with every heartbeat and is in constant
fluctuation 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.
