Taking measurements on the right arm
The air tube will be at the side of your elbow.  
Be careful not to rest your arm on the air tube.
Note: The blood pressure can differ between the 
right arm and the left arm, and therefore also 
the measured blood pressure values can be 
different. OMRON recommends to always 
use the same arm for measurement. If the 
values between both arms differ substantially, 
please check with your physician which arm 
to use for your measurement.
•  Use a soft and dry cloth, or a soft and moistened 
cloth and neutral soap to clean on the arm cuff.
•  Do not use petrol, thinners of similar solvents to 
clean the arm cuff.
•  Do not store the arm cuff to extreme 
temperatures, humidity, direct sunlight, dust or 
corrosive vapours.
•  Do not bend or crease the air tube excessively.
