Instruction Manual
EN
Model: MW821 f
The National High Blood Pressure Education Pr ogram Coordinating
Committee has developed a blood pressure standar d, classifying blood
pressure ranges into 4 stages. (Ref. The Sev-
enth Report of the Joint National Committee
on Prevention, Detection, Evaluation, and
T reatment of High Blood Pressure-Complete
Report JNC-7, 2003).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 . Y our
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 pr essure,
keeping long- term records is r ecommended.
Please download the blood pressure log at
www .rossmax.com.
Attention: Consult the accompanying documents. Please read this
manual carefully before use. For specic information on your
own blood pressure, contact your physician. Please be sure
to keep this manual.
Blood pressure measurements determined with MW821f are equivalent to
those obtained by a trained observer using cuff/stethoscope auscultation
method, within the limits prescribed by the American National Standard,
Electronic or Automated Sphygmomanometers. This unit is to be used by
adult consumers in a home environment. Do not use this device on infants
or neonates. MW821f is protected against manufacturing defects by an
established International Warranty Program. For warranty information,
you can contact the manufacturer, Rossmax International Ltd.
1. Introduction
3. Real Fuzzy Measuring Technology
4. Preliminary Remarks
This unit uses the oscillometric method to detect your blood pressure. Be-
fore the cuff starts inating, the device will establish a baseline cuff pres-
sure equivalent to the air pressure. This unit will determine the appropriate
ination level based on pressure oscillations, followed by cuff deation.
During the deation, 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 0120”. 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.

EN 1060-3: 1997/A2: 2009 Non-invasive sphygmomanometers
- Part 3 - Supplementary requirements for electro-mechanical blood pres-
sure measuring systems

mated non-invasive sphygmomanometers.
This blood pressure monitor was designed for long service time. To en-
sure continued accuracy, it’s recommended that all digital blood pressure
monitors require re-calibration. This monitor (under normal usage with
approx. 3 measurements a day) does not require re-calibra-
tion for 2 years. Once the unit should be re-calibrated the
device will display . The unit should also be re-calibrated
if the monitor sustains damage due to blunt force (such as
dropping) or exposure to uids and / or extreme hot or cold
temperature / humidity changes. When appears, simply
return to your nearest dealer for re-calibration service.
7. Display Explanations
Blood pressure uc-
tuates all the time!
You should not be
overly worried if you
encountered two or
three measurements
at high levels. Blood
pressure changes over
the month and even
throughout the day.
It is also inuenced
by season and tem-
perature.

11. Using the Talking Function
1. Press down and lift the battery cover in
the direction of the arrow to open the
battery compartment.
2. Install or replace 4 “AA” sized batteries
in the battery compartment according
to the indications inside the compart-
ment.
3. Replace the battery cover by clicking
in the bottom hooks rst, then push in
the top end of the battery cover.
4. Replace the batteries in pairs. Remove batteries when unit is not in use for
extended periods of time.
You need to replace the batteries when
1. low battery icon appears on display.
2. the ON/OFF/ST ART key is pressed and nothing appears on display.
Caution
1. Batteries are hazardous waste. Do not dispose them together with the house-
hold garbage.
2. There are no user serviceable parts inside. Batteries or damage from old bat-
teries are not covered by warranty.
3. Use exclusively brand batteries. Always replace with new batteries together.
Use batteries of the same brand and same type.
1. Select English or Spanish by pressing the Language
Selection key labelled with an “L” and located on
the back of the unit.
•”L1” will appear on the display for English.
•”L2” will appear on the display for Spanish.
2. Turn the talking feature on (or off) by pressing the
Speaker ON/OFF key located on the front of the unit.
2. Name/Function of Each Part
1. Unwrap the arm cuff, leaving the end of the cuff through the D-ring
of the cuff.
2. Put your left arm through the cuff loop. The color strip indication
should be positioned closer to you with the tube pointing in the direc-
tion of your arm (Fig. 1). T urn your left palm upward and place the
edge of the arm cuff at approximately 1.5 to 2.5 cm above the inner
side of the elbow joint (Fig. 2). Tighten the cuff by pulling the end of
the cuff.
3. Center the tube over the middle of the arm. Press the hook and loop
material together securely . Allow room for 2 fingers to fit between the
cuff and your arm. Position the artery mark (Ø) over the main artery (on
the inside of your arm) (Fig. 3,4).
Note: Locate the main artery by pressing with 2 fingers approximately
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 .
The National High Blood Pressure Educa-
tion Program Coordinating Committee
has developed a blood pressure stand-
ard, classifying blood pressure ranges
into 4 stages. This unit is equipped with
innovative blood pressure risk indicator,
which visually indicates the assumed risk
level (prehypertension / stage 1 hyper-
tension / stage 2 hypertension) of the
result after each measurement.
This unit is equipped with an Irregular Heart-
beat Detector (IHB) which allows those who
have an irregular heartbeat to obtain accurate
measurements alerting the user of the pres-
ence of an irregular heart beat during the
measurement.
Note: It is strongly recommended that you
consult your physician if the IHB icon
() appears often.

adapters with required voltage and current
indicated near the AC adapter jack.)
Caution: 1. Please unload the batteries when
operating with the AC mode for
a longer period of time . Leaving
the batteries in the compartment
for a long time may cause leakage,
which may lead to damage of the

error keeps occurring, r eturn the device to your local distribu-
tor or service center .
Air Circuit Abnormality: Make sure the L-Plug is secur ely
connected to the air socket on the side of the unit and meas-
ure again quietly . If the errors still occur , r eturn the device to
your local distributor or service center for help.
Pressure Exceeding 300 mmHg: Switch the unit of f and
measure again quietly . If the error keeps occurring, r eturn the
device to your local distributor or service center .
Data Error: Remove the batteries, wait for 60 seconds, and
reload. If the err or keeps occurring, return the device to your
local distributor or service center .
