2. Preparation
2.4 Applying the Arm Cuff
•The following steps are for applying the arm cuff to your left arm. 
When you take a measurement on your right arm, follow the cuff 
wrap instructions for a right arm use mentioned under “To take a 
measurement on your right arm” located at the end of this sub-
section.
•The blood pressure can differ between the right arm and the left 
arm, and the measured blood pressure readings can be different. 
OMRON recommends to always use the same arm for 
measurement. If the readings between both arms differ 
substantially, check with your physician to determine as to which 
arm to use for your measurements.
• Remove tight-fitting or thick clothing from your arm while taking a 
measurement.
1. Plug the arm cuff into your monitor by inserting 
the air plug into the air jack securely until it 
clicks.
