method, within the limits prescribed by the American National Standard, Elec-
tronic or Automated Sphygmomanometers. This unit is to be used by adult
consumers in a home environment. Do not use this device on infants or neo-
nates.

on your own blood pressure, contact your physician.
Please be sure to keep this manual.

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.
4. Preliminary Remarks
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.
This blood pressure monitor was designed for long service time. To ensure
accurate measurements, it is recommended that calibration be completed ev-
ery two years.

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.

Memory Mark: Shows the number of stored measurements
Pulse Mark: Shows the pulse rate per minute
Weak Battery Mark: Appears when batteries should be replaced
Measurement Error: Make sure the L-plug is securely connected to the
air socket and measure again quietly. Wrap the cuff correctly and keep arm
steady during measurement. If the error keeps occurring, return the device to
your local distributor or service center.
Air Circuit Abnormality: Make sure the L-Plug is securely connected to
the air socket on the side of the unit and measure again quietly. Another pos-
sible cause can be due to the short circuit of the microphone embedded in the
cuff. If the errors still occur, return the device to your local distributor or service
center for help.
Pressure Exceeding 300 mmHg: Switch the unit off and measure again
quietly. If the error keeps occurring, return the device to your local distributor
or service center.
Data Error: Remove the batteries, wait for 60 seconds, and reload. If
the error keeps occurring, return the device to your local distributor or service
center.
Exceeding Measurement Range: Measure again quietly. If the error
keeps occurring, return the device to your local distributor or service center.
7. Installing Batteries
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 compartment.
3. Replace the battery cover by clicking in the
bottomhooksrst,thenpushinthetopendofthebatterycover.
4. As the supplied batteries are for test only, they may be discharged
earlier than batteries you buy in stores. Replace the batteries in pairs.
Remove batteries when unit is not in use for extended periods of time.

6
You need to replace the batteries when:
1. low battery icon appears on display.
2. the ON/OFF/START key is pressed and nothing appears on display.
1. Batteries are hazardous waste. Do not dispose them together with the
household garbage.
2. There are no user serviceable parts inside. Batteries or damage from old
batteries 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.
8. Applying the Cuff
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
direction of your arm (Fig.1). Turn 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.

7
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.
• 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 about 5 minutes before taking the next measurement.
1. Press the ON/OFF/START key. All displays will appear for approximately
one second before returning to “0”.
2. Theunitwillautomaticallyinatetotheappropriateinationlevelbasedon
the user’s pulse oscillations. Measurement will then begin. It is important
toremainstillandquietduringmeasurement.Anysignicantmovement
may affect measurement results.
3. When the measurement is completed, systolic, diastolic and pulse will be
shown simultaneously and be saved automatically in memory system. Up
to 90 memories can be saved.
4. Measurement is now completed. Press the ON/OFF/START key to turn

9
off the power. If no key is pressed, the unit will shut off automatically in 1
minute.
Thismonitorwillre-inateautomaticallytoapprox-
imately 220 mmHg if the system detects that your
body needs more pressure to measure your blood
pressure.
Note:
1. This monitor automatically switches off approximately 1 minute after
last key operation.
2. To interrupt the measurement, simply press the Memory or ON/OFF/
STARTkey;thecuffwilldeateimmediately.
3. During the measurement, do not talk or move your arm or hand
muscles.
10. Recalling Values from Memory
1. To recall stored blood pressure readings
from memory, simply press the Memory key.
The last set of memorized readings will be
displayed.
2. Another press of the Memory key will recall
the previous set of readings.
3. All readings stored in memory will be
displayed with its sequence number.
11. Clearing Values from Memory
1. Press and hold the Memory key for
approximately 5 seconds, then the data
in the memory zone can be erased
automatically.
