compare readings obtained with the MF-46 system with values measured  
by a trained observer using a manual sphygmomanometer at least every  
6 months.  
Indications for Use  
The MF-46 system is intended for the non-invasive measurement of systolic  
and diastolic blood pressure and determination of heart rate in adult patients,  
Blood pressure measurements determined with this device are equivalent  
i.e., age 15 and above. The product is recommended for use by patients to those obtained by a trained observer using the cuff stethoscope

PRECAUTIONS FOR USE  
TIPS ON TAKING YOUR BLOOD PRESSURE  
Do not use this instrument without consultation with your doctor if you are under dialysis  
therapy or on anticoagulants, antiplatelets or steroids. Use of this instrument under such  
conditions could cause internal bleeding.  
Take blood pressure measurement with the correct posture and do not move nor  
speak during measurement.  
Avoid exercise, eating, drinking alcohol, smoking and other activities that affect your  
blood pressure right before a measurement.  
To avoid any possibility of accidental strangulation, keep this unit away from children and  
10  
do not drape AIR HOSE around your neck.  
Take your blood pressure every day at the same time.  
For specific information on your blood pressure, contact your physician. Never make any  
judgment on measurement results on your own.  
The ambient temperature sould be approximately 68˚F (20˚C) when you take your  
blood pressure.  
Use of this device in areas near portable phones, microwave ovens or other devices with  
strong electromagnetic field may cause malfunctions.

Blood pressure changes shown below.  
Blood pressure is a measurement of the force exerted by the heart in pumping the blood  
through the arteries and the resistance by the veins in this flow.  
Blood pressure changes easily as influenced by mental and physical factors

Changes in the surroundings such as movement or noise, etc.  
Time  
In general, blood pressure is highest during the working hours and gradually decreases during  
the afternoon and evening hours. It is low during sleep and slowly increases at a relatively fast  
rate after arising from bed.  
Blood pressure measured at home tends to be lower than when measured  
in a hospital, clinic or doctor's office.  
When blood pressure is measured in a hospital, it could be higher than when measured at  
home. This is because you are tense at the hospital and relaxed at home. It is important to  
know your stable normal blood pressure at home.  
Let a qualified physician interpret your blood pressure readings.  
Depending on your age, weight and general condition, blood pressure can be slightly different.  
Consult with your doctor on determining what blood pressure is normal for you.  
Close the battery compartment cover.  
Year flashes on the display.  
Use alkaline batteries to increase battery life. Use of regular Carbon-  
Zinc batteries will necessitate more frequent replacement. The  
enclosed batteries are for monitoring, and their life may be shorter  
than that of commercial batteries.

CORRECT MEASURING POSTURE  
see fig.2  
Automatic Repressurization  
If the pressure applied is judged insufficient in the early  
phase of measurement or if movement of arm or hand  
occurs during measurement, the unit will inflate again to a  
level about 40 mmHg higher. Automatic Repressurization  
is repeated until a measurement is made. However, this  
does not indicate a problem.  
To manually control pressurization, hold down ON/OFF  
BUTTON immediately after the start of inflation and  
release it when the pressure reaches the level 50 mmHg  
higher than the expected maximum systolic pressure. If  
the pressure value has exceeded 180 mmHg, the inflation  
will stop when the key is released. Pressure can be  
increased to approximately 300 mmHg.  
Sit at the table and let the table support your arm as you take the blood pressure measurement.  
Make sure that the measurement location on the upper arm is at approximately the same height as the heart,  
and that the forearm is extended naturally on the table and does not move.  
You may lie on your back and take the measurement. Look at the ceiling, stay calm, and do not move your neck or body during the  
measurement. Again, make sure that the measurement location on the arm is at approximately the same height as the heart.

With the tube of the cuff positioned in the direction of the fingertips, place it on your

Wrap the cuff around the arm with the edge of the cuff approximately 1 inch (2.5 cm)  
above the elbow.  
page 6  
MEMORY FUNCTIONS  
see fig.5  
Press the surface of the cuff to make sure that it is attached securely.  
Measured result is stored in either M1 or M2. Each of two memory banks can hold up to 30 results and their average. When the number of  
measurements exceeds 30, the oldest data will be deleted to record new data. You may decide which bank to store your measurement  
results to avoid data mixture with someone else's, or may use two banks to save data measured in the morning and evening separately.  
When wrapping the cuff, wrap it loosely enough around the arm so that two fingers can be placed between  
the cuff and the arm. If the cuff is wrapped more tightly or loosely than this, inaccurate blood pressure  
readings may result.  
Recalling measured data  
If you are wearing a shirt that might restrict circulation in your upper arm or you roll your sleeve up over  
the upper arm, the blood flow will be restricted, preventing accurate measurement.
