D40 Owner's Manual
Testing Your Blood Pressure
Fitting the Cuff
1. Connect the air plug of the tubing to the air jack of the device.
2. Assemble the cuff as shown in the illustration.
The smooth surface should be inside the cuff loop
and the metal D-ring should not touch your skin.
Note:
• Before using the cuff, be sure the cuff size fits with your
upper arm circumference.
3. Stretch your left (right) arm in front of you with your
palm facing up.
Slide and place the cuff onto your arm with the air
tube and artery mark region (in red) toward the
lower arm.
Wrap and tighten the cuff above your elbow. The
red line on the edge of the cuff should be approximately 0.8 to 1.2 inches (2 to 3 cm)
above your elbow. Align the tube over the main arteries on the inside.
4. Leave a little free space between the arm and the cuff. You should be able to fit 2
fingers between them.
5. Press the hook material firmly against the pile material. The top and bottom edges of
the cuff should be tightened evenly around your upper arm.
Proper Measurement Position
1. Sit down for at least 10 minutes before measuring.
2. Place your elbow on a flat surface. Relax your hand with the
palm facing up.
3. Make sure the cuff is about the same height as the location of
your heart.
4. After the device is turned on, the cuff will begin to inflate
automatically.
Remain still and do not talk or move during the measurement.
