   The time format starts to blink. The product is now in time format adjustment mode.
   If no button is pressed for 60 seconds, the product exits time and date adjustment mode.

5. Press A7 to confirm. The product is now in month adjustment mode.

6. Repeat steps 4 – 5 to set the month, date, hour and minutes.

Connecting the cuff

1.  Insert the rubber air tube A3 into the air tube connector A4. The connector must be completely inserted to prevent air leakage during blood pressure measurements.

Applying the cuff

1. Place the cuff A2 around a bare upper arm.
   A2 must be placed 1-2 cm above the elbow joint.

2.  Choose an arm to measure on. Always measure on the same arm.
   If A2 is applied on the left arm, A3 must be on the inside of the arm, aligned with the middle finger.
   If A2 is applied on the right arm, A3 must be at the side of the elbow.
   A2 should be tight but comfortable. It should be possible to insert a finger between the arm and A2.

Body posture during measurement

Sitting down

1.  Sit down.
2.  Put your feet flat on the floor.
3.  Place your hand on a flat surface with the palm up. Do not rest your arm on A3. This may restrict the airflow to A2.
4. Position your arm so A2 is at the same height as your heart.
5. Sit calmly for 5 minutes before starting the blood pressure measurement.

Lying down

1. Lie on your back.
2. Place your arm straight along your side with the palm up.
3. Position your arm so A2 is at the same height as your heart.
4.  Lie calmly for 5 minutes before starting the blood pressure measurement.

Measuring blood pressure

1. Press A7.
   All symbols – A8 to Ay – are shown on the display. If not all symbols are visible, contact the service center.
   The current memory group starts to blink in the place of At.
   Memory groups can be used to store measurements for multiple people on the same device.

2.  Press A6 to switch memory groups.

3. Press A7 to confirm.
   The memory group is also confirmed automatically after 5 seconds of inactivity. The display shows the most recent measurements.
   If no measurements are stored in the memory group, the display shows zeroes. The product starts to seek zero pressure.
