1. Introduction
Blood pressure measurements determined with S150 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. S150 is protected against manufacturing defects by an established
International Warranty Program. For warranty information, you can contact the
manufacturer, Rossmax International Ltd. or your local distributors.
Attention:
2. How This Unit Works
S150 uses the oscillometric method to detect your blood pressure. Before
the cuff starts inflating, the device will establish a baseline cuff pressure,
which is equivalent to the air pressure. The measurement of your blood
pressure is based on this baseline pressure. After the cuff inflates to block
your blood in the artery, the deflation process starts. During the deflation of
the wrist cuff, the monitor is detecting the pressure oscillations generated
by the beat-to-beat pulsatile.
Consult the accompanying documents. Please read this manual
carefully before use. For specic infor-mation on your own blood
pressure, contact your physician. Please be sure to keep this
manual.
Any muscle movement during this period of time will cause measurement
error. After detecting the amplitude and the slope of the pressure oscillations
during the deflation process, your S150 will determine for you the systolic
and diastolic pressures, and your pulse rate is detected at the same time.

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-calibration 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 fluids and / or extreme hot or
cold temperature / humidity changes. When appears,
simply return to your nearest dealer for re-calibration
service.
5. Blood Pressure Standard
The National High Blood Pressure Education Program Coordinating 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 JNC7, 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
records is recommended. Please download
the blood pressure log at our website www.
rossmaxhealth.com.
6. Blood Pressure Fluctuation
Blood pressure uctuates 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 temperature.

ies together. Use batteries of the same brand and same type.
9. Applying the Cuff
1. Remove all watches, jewelry, etc. prior to attaching the wrist monitor.
Clothing sleeves should be rolled up and the cuff should be wrapped
on bare skin for correct measurements.
2. Apply cuff to left wrist with palm facing up as Fig. A.
3. Make sure the edge of the cuff is about 1 cm from the palm as Fig. B.
4. In order to ensure accurate measurements, fasten the velcro strap
securely around your wrist so there is no extra space between the
cuff and the wrist as Fig. C. If the cuff is not wrapped tight enough,
the measurement values may be false.
5. If your physician has diagnosed you with poor circulation on your left
arm, carefully place the cuff around your right wrist as shown in Fig. D.

10. Correct Measuring Posture
1. Place your elbow on a table so that the cuff is at the same level as your
heart as Fig. A. Note: Your heart is located slightly below your armpit
a bit to the left of the middle of your chest. Relax your entire body,
especially the area between your elbow and fingers.
2. If the cuff is not at the same level as your heart or if you can not keep
your arm completely still throughout the reading, use a soft object such
as a folded towel to support your arm as Fig. B. Do not allow hard
objects to come in contact with the wrist cuff.
3. Turn your palm upwards.
4. Sit upright in a chair, and take 5-6 deep breaths.Avoid leaning back
while the measurement is being taken as Fig. C.

11. 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 physiologic condition and other factors. For greatest accu-
racy, 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 feel-
ing cold or hot, wait a while before taking a measurement.
• If the monitor is stored at very low temperature (near freez ing), have it
placed at a warm location for at least one hour before using it.
• Wait 5 minutes before taking the next measurement.
1. Place the cuff on the wrist. Press the ON/OFF/START key. All digits will
light up, checking the display functions. The checking procedure will
complete in 2 seconds.
2. After all symbols appear, the display will show a blinking “0”. At this
time, the monitor is ready to measure.
3. Once the monitor inflates the cuff to approximately 180 mmHg,
measurement will begin.
4. When the measurement is completed, systolic blood pressure, dias-
tolic blood pressure, and pulse will be shown simultaneously and be
saved automatically in the memory system. Up to 90 measurements
can be saved in the memory.
5. Press the ON/OFF/START key to turn the monitor off. If no key is
pressed, the monitor will automatically shut off in 60 seconds.
This monitor will re-inflate automatically to approximately 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 ON/OFF/START key or
Memory key; the cuff will deflate immediately.
3. During the measurement, do not talk or move your arm or hand
muscles.
12. Recalling Values from Memory
To read memory values, press the Memory key. The memory values will
be shown on the LCD display. The last measurement will be shown first.
Every new press of the Memory key calls for one prior value stored.
Note: The memory bank can store up to 90 readings per memory zone.
When the number of readings exceeds 90, the oldest data will be
replaced with the new record.
13. Clearing Values from Memory
Note:
1. The data in the memory will not be lost even when the Blood Pressure
Monitor is switched off.
2. You can erase the memories stored by:
• remove the batteries.
• press and hold the Memory key for more than 5 seconds.
3. The data in the memory zone can be erased if any of the batteries is
moved away. (Suggest the users to first record the data on the Blood
Pressure Log before replace or move away the batteries.)
