CAUTION! Do not use rechargeable batteries. Remove batteries if the device will not be used for an extended period.

Taking a Measurement

For the most accurate results, follow these steps precisely.

1. Rest: Sit quietly for 5 minutes before measuring. Avoid caffeine, exercise, and smoking for 30 minutes prior.
2. Position: Sit with back straight, feet flat. Place arm on a table so the cuff is at heart level.
3. Select User: Press the User button (1 or 2) to select your memory profile. The user icon will appear on the display.
4. Start Measurement: Press the START/STOP button. The cuff will inflate automatically.
5. Remain Still: Do not move, talk, or clench your fist during inflation and measurement.
6. Read Results: The systolic pressure, diastolic pressure, and pulse rate will display. The WHO indicator bar will light up. Symbols for AFIB or irregular heartbeat may appear if detected.
7. Cuff Deflation: The cuff will deflate completely. The device will automatically store the reading in memory for the selected user.

Tip: Take measurements at the same time each day for consistent tracking.
