Note:
If it is not possible to fit the cuff on your left arm, it can also
be placed on your right arm. However, all measurements
should be made using the same arm.
The device is not supposed to be used when your arm is
wounded or injured.
To use on the right arm, you must position the artery
symbol " " over the main artery. Locate the main artery
by pressing with two fingers approximately 1" (2 cm) above
the bend of your elbow on the inside of your right arm.
Identify where the pulse can be felt the strongest. This is
your main artery.
