Precautions for use

1.  If you suffer from heart disease, high blood pressure or other 

circulatory disease, consult your physician before using the monitor.

2.  If you feel abnormal pressure of the cuff during use or any other 

irregularity, reduce the pressure by immediately switching off the 
power or remove the batteries and consult the sales outlet where 
purchased.

3.  If you think the measurement is abnormal or if measurement makes 

you feel unwell, discontinue use and consult your physician.

4.  Blood pressure measurement may not be possible for anyone with 

a weak pulse or arrhythmia.

5.  Repeated blood pressure measurement may cause problems such 

as congestion or swelling in some people.

6.  Frequently repeated blood pressure measurements will not give 

accurate results. Allow an interval of about 1 minute between 
measurements.

7.  If you suffer from a severe problem with blood circulation in your 

arms, consult your physician before using the monitor. Failure to do 
so could be hazardous to your health.

8.  Measurement may not be possible for anyone with insuffi cient 

blood fl ow to the area where measurements will be taken or who 
suffers from a frequent irregular heartbeat. Consult your physician 
for advice on whether to use the monitor.

9.  DO NOT wrap the cuff around an injured wrist.

GENERAL REMARKS

8.  Measure your blood pressure when you are relaxed and still. Keep 

the center of the cuff at the level of your heart and DO NOT move 
your arm or talk.

9.  DO NOT measure blood pressure when the cuff has been on your 

wrist for a few minutes or more. During this time, your wrist will have 
built up a higher blood pressure and you will not get valid reading.

10. If the Body Movement Indicator or Irregular Heartbeat (IHB)Indicator 

is displayed, relax and measure your blood pressure again. If the 
Irregular Heartbeat (IHB) Indicator appears frequently, you are advised 
to consult a doctor about your health condition. (

Defi nitions and Classifi cations of Blood Pressure Levels

12. Intended Use

•  This device is noninvasive blood pressure monitor by oscillometric 

method. This device can measure the systolic blood pressure (SYS), 
the diastolic blood pressure (DIA) and the pulse rate automatically.

•  This device is intended to be used for checking personal health 

condition at home under the direction of a physician and is not 
intended to be a diagnostic device.

•  This device is not intended for use with neonates or infant, and 

not intended for automatic cycling measurement.

GENERAL REMARKS

Measure your blood pressure at the same time each day.

*   Your blood pressure changes all the time. This means that data 

gathered over a long period has far more signifi cance than data 
from just one measurement. For this reason, you must measure your 
blood pressure on a daily basis. Ideally, you should measure your 
blood pressure at the same time each day, wherever possible.
