APPLYING THE CUFF ON THE RIGHT ARM
When taking a measurement using the right arm use this instruction
for Step 6 on page 25.
Apply the cuff to your right upper arm so the thumb grip is centered
on the inside of your inner arm. The bottom of the cuff should be
approximately 1/2'' above your elbow.
NOTE: Be careful not to rest your arm on the air tube. This will restrict
the flow of air to the cuff.
