Do not confuse self-monitoring with self-diagnosis. This  
unit allows you to monitor your blood pressure. Do not  
begin or end medical treatment based solely on the  
measurements of this device. Consult a physician for  
treatment advice.  
If “MEM” shows, the displayed  
measurement value is from the  
memory, and not necessarily  
from the last reading.  
If you are taking medication, consult your physician to  
determine the most appropriate time to measure your  
blood pressure. Never change a prescribed medication  
without consulting your physician.  
Weak battery Batteries are low and need  
to be replaced.

·
This unit is not suitable for continuous monitoring during  
medical emergencies or operations.  
Inflating  
Unit is inflating with air to  
obtain the needed level of  
pressure.  
If the cuff pressure exceeds 300mmHg, the unit will  
automatically deflate. Should the cuff not deflate when  
pressures exceeds 300mmHg, detach the cuff from the  
wrist and press the ON button to stop inflation.  
Deflating  
Wrist cuff air is exhausting,  
or deflating.  
·
To avoid measurement errors, carefully read this manual

Caring for your blood pressure monitor  
ABOUT BLOOD PRESSURE  
To ensure you receive the maximum benefit from using this  
product, please observe the following care guidelines.  
What is blood pressure?  
·
When not in use, store the main unit in the protective  
plastic container that came with it.  
Blood pressure is the force generated by the blood against  
the walls of arteries during cardiac contraction and relaxation  
(e.g., the pumping action of the heart).  
·
Do not immerse the main unit in water. If it comes in  
contact with water, dry it immediately with a soft lint-free  
cloth.  
What are systolic pressure and diastolic pressure?  
When ventricles contract and pump blood out of the heart,  
blood pressure reaches its maximum value. This highest  
pressure in the cycle is known as systolic pressure. When  
the heart relaxes between heartbeats, the lowest blood  
pressure is diastolic pressure.  
·
Use a soft, slightly moistened cloth to wipe off the main  
unit casing and cuff. Do not use abrasive or corrosive  
cleaning agents, as these may cause damage.  
·
·
·
·
Remove the batteries whenever you are planning to store  
the main unit for a long period of time.  
What is mean arterial pressure (MAP)?  
When replacing batteries, use new batteries as specified  
in this user manual. Do not mix new and old batteries.  
The mean arterial pressure (MAP) is the average pressure  
that forces blood through the arteries. It is not the average of  
the systolic and diastolic blood pressure; rather, MAP  
corresponds to a state of balance between the compressive  
and expansive forces acting on the arterial wall when there  
is no distension outward or inward. MAP is an excellent way  
to evaluate the stress on the walls of your blood vessels,  
and can be used to evaluate excessive load on the  
cardiovascular system. Show your MAP history to your doctor  
to provide additional information that may help him or her  
understand your situation.  
Do not place objects such as stickers on the wrist cuff or  
main unit, as these may impair the measurement.  
Do not subject the main unit to excessive force, shock,  
dust, temperature changes, or humidity. Such treatment  
may result in malfunction, a shorter electronic life span,  
damaged batteries, or distorted parts.  
·
·
Do not tamper with the internal components. Doing so  
will terminate the product warranty and may cause  
damage. The main unit contains no user-serviceable  
parts.  
Why measure your blood pressure?  
If you no longer need to use this product, protect the  
environment by bringing it to your dealer or designated  
collection point for proper disposal.  
Blood pressure measurement can highly reflect one’s health  
condition. High blood pressure is potentially linked to serious  
illnesses such as stroke, heart disease and kidney failure.  
Since there is no symptom most of the time, many  
 
4
hypertensive people do not realize they are at risk until their  
health is seriously threatened.  
·
Only a physician can tell you your normal blood pressure  
range and the point at which you are at risk. Consult your  
physician to obtain these values. If the measurements  
taken with this product fall outside the range, consult your  
physician.  
What is the standard blood pressure classification?  
The following chart (Figure 3) was taken from the World  
Health Organization (WHO), and describes the various  
classifications.  
Why does my blood pressure fluctuate throughout the  
day?  
Please note:  
Individual blood pressure varies greatly both on a daily and a  
seasonal or temperature basis. These variations may be more  
pronounced in hypertensive patients. Normally the blood  
pressure rises while at work and is at its lowest during sleep.  
Figure 4 below illustrates the variations over a single day  
with measurement taken every five minutes. The thick line  
represents sleep time. The rises in blood pressure at 4 PM (A  
in the graph) and 12AM (B in the graph) correspond to an  
attack of pain and sexual intercourse (Beven, Honour & Stott,  
Clin. Sci. 36:329, 1969).  
·
·
Hypotension value is for reference only.  
Blood pressure is considered high when either the  
diastolic or systolic blood pressure value exceeds the  
normal range.

HOW DOES THE BLOOD PRESSURE ?  
Systolic (mmHg)  
Figure 3  
This product uses the Oscillometric Measuring method to

detect your blood pressure. Before every measurement, the  
main unit establishes a zero pressureequivalent to the air  
pressure. Then it starts inflating the wrist cuff to 180mmHg  
or higher until it senses that it has blocked your blood in the  
artery. After that, the deflation process starts, during which  
time the main unit detects pressure oscillations generated  
by beat-to-beat pulsatile, which is used to determine the  
systolic, mean and diastolic pressure, and also your pulse  
rate. Any motion during this period will result in an incorrect  
measurement. After all readings are determined and  
displayed on LCD, the measurement is finished and the wrist  
cuff automatically deflates.  
Note: Replace the batteries whenever the weak battery  
mark ( ) shows, the display is dim, or the display does  
not illuminate when the power is on. Replace all the  
batteries at the same time it is dangerous to mix old and  
new batteries.  
Contact your local waste disposal authority for instructions  
on how to dispose of used batteries. Used batteries can  
be harmful to the environment, and should not be thrown  
out with household trash.  
Setting the date, time, and measurement units  
It is important to set the clock before using your blood  
pressure monitor, so that a time stamp can be assigned to  
each record that is stored in the memory.  
GETTING STARTED  
To set the date, time, and measurement unit:  
Installing and replacing the batteries  
To install the batteries:  
1. Press and hold SET for 2 seconds to enter the setting  
mode.  
1. Slide off the battery cover (Figure 5a).  
The setting order is as follows: 12/24 hour format, hour,  
minute, year month/day or day/month format, month,  
date, and measurement unit (mmHg or kPa).  
2. Install the batteries by matching the correct polarity, as  
shown by Figure 5b. Always use the correct battery type  
(2 Alkaline LR03 AAA-size).  
Note: Select the measurement unit most applicable for  
your region. mmHg is used worldwide, including the  
United States and most of Europe. kPa is primarily used  
in the People's Republic of China.  
3. Replace the cover (Figure 5c).  
2. Press MEM / UP to increase a value or change the  
setting.  
3. Press SET to accept the change and switch to the next  
setting.  
4. To exit the setup menu anytime, press ON.

Positioning the wrist cuff  
It is important to properly position the wrist cuff to ensure that you receive an accurate reading.  
1. Remove all accessories (watch, bracelet, etc.) from your left wrist. If your physician has diagnosed you with poor circulation  
in your left arm, use your right wrist.  
2. Roll or push up your sleeve to expose the skin.  
3. Apply the cuff to your left wrist with your palm facing up (Figure 6a).  
4. Position the edge of the cuff about 1 centimeter from the bottom of your palm (Figure 6b).  
5. Fasten the wrist cuff around your wrist, leaving no extra room between the cuff and your skin. If the cuff is too loose, the  
measurement will be inaccurate (Figures 6c 6d).

TAKING A BLOOD PRESSURE  
MEASUREMENT  
1. Choose the position you from which you wish to measure  
sitting or lying down.  
You can choose to take your blood pressure while sitting or lying  
down.  
2. Position your body so that your wrist is parallel with your  
heart, using the chart and illustrations below as a guide.  
Helpful Tips for taking a measurement:  
IF you are…  
THEN…  
·Be sure to set the clock before taking your first measurement, or  
whenever you replace the batteries, so that the date and time are  
stored in the memory with your history. For instructions, refer to  
page 6.  
Place your elbow on a table, using  
the plastic storage case or other  
object as a support under your  
forearm. Your wrist should be parallel  
with your heart with the palm facing

·Wait at least one hour before taking your blood pressure if you  
have just eaten a large meal.  
Place your arm across your chest  
with the wrist parallel to your heart.  
Hold your elbow with the other hand.  
Sitting down with  
no armrest  
·Do not smoke or drink alcohol before taking your blood pressure.  
·Do not measure your blood pressure if you are under stress.  
·Wait at least 3 minutes between measurements. This allows your  
blood circulation to recover.  
·For a meaningful comparison, try to measure under similar  
conditions. For example, take daily measurements at approximately  
the same time, on the same wrist, or as directed by a physician.  
·To stop the measurement process at any time, press theON button.  
·The main unit automatically switches off 1 minute after taking a  
measurement. To save the battery life, press the ON button as  
soon as you are finished.

RECALLING MEASUREMENTS STORED IN  
THE MEMORY  
Position your wrist on a support, cushion,  
or your thigh so that it is parallel with your  
heart with the palm facing up.  
The memory can hold up to 8 records. The records are  
automatically stored each time you take a new measurement.  
Note:  
· The most recent record (1) is shown first. Each new  
measurement is assigned to the first (1) record.All other  
records are pushed back one digit (e.g., 2 becomes 3,  
and so on), and the last record (8) is dropped from the  
list.  
3. Relax your hand.  
4. Press the ON button.  
· Press MEM / UP again to see additional records.  
Result: After a few seconds, the blood pressure monitor  
beeps and begins inflating the wrist cuff. It then slowly  
deflates until there is another beep, signifying that the  
measurement is complete. Dont move from the first beep  
until the last to ensure a more accurate measurement.  
Your systolic and diastolic pressure readings flash on the  
display, followed by MAP (Mean Arterial Pressure, see  
page 4) and pulse per minute readings every two  
seconds. The measurement is automatically stored as  
the first (1) entry in the memory; the last entry (8) is  
dropped, and all the entries in between move up one  
digit (e.g., 7 becomes 8, and so on).  
· The date and time of measurement are shown with each  
record.  
· Memory records will be kept even when the batteries  
are replaced.
