CAUTION! Ensure correct cuff positioning for accurate readings.

Taking a Measurement

Follow these steps for accurate measurement.

1. Sit quietly for 5 minutes before measuring.
2. Apply cuff correctly as described in Initial Setup.
3. Press START/STOP button to begin.
4. Remain still and quiet during inflation and measurement.
5. Device will automatically inflate, measure, and deflate.
6. Results will display systolic/diastolic pressure and pulse rate.
7. Reading is automatically stored in memory.
8. To turn off, press START/STOP again or wait 1 minute for auto power-off.

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

Memory Function

Access and manage stored readings.

1. View memory: Press Memory button to cycle through stored readings.
2. Each display shows: Reading number, systolic/diastolic pressure, pulse rate, date/time, irregular heartbeat symbol if detected.
3. Clear memory: Press and hold Memory button for 5 seconds while in memory mode.
4. Average reading: Device calculates average of last 3 readings taken within last 10 minutes.

Note: Memory is retained when batteries are removed (for approximately 3 minutes).

Understanding Results
