Taking a Measurement

For accurate results, remain still and quiet.

1. Position: Sit on a chair with back supported, feet flat on floor. Place cuff on left arm (or as advised by doctor).
2. Start: Press START/STOP button. The cuff will inflate automatically.
3. Measurement: Remain still, do not talk. The cuff will deflate slowly. Your readings will appear on the display.
4. Completion: The monitor beeps and displays systolic, diastolic pressure, and pulse rate. The cuff deflates fully.
5. Power Off: The device turns off automatically after 1 minute, or press START/STOP to turn off immediately.

WARNING! Do not move or tighten muscles during measurement. Wait at least 3 minutes between readings on the same person.

Understanding the Display

After measurement, the LCD shows:

• Large Numbers: Systolic / Diastolic pressure (e.g., 120 / 80 mmHg).
• Pulse Rate: Smaller number with heart icon (e.g., 72 bpm).
• WHO Bar Graph: Color-coded bar (Green=Optimal/Normal, Yellow=High-Normal/Mild, Red=Moderate/Severe).
• Irregular Heartbeat Symbol: Flashing heart icon appears if irregular rhythm is detected.
• Memory Symbol (M): Indicates reading is stored.
• Cuff Fit "OK": Appears if cuff was applied correctly.

If an error occurs, an error symbol (E) with a number will flash. Refer to troubleshooting.

Memory Function

Stores last 30 readings with date and time.

1. View Memory: Press MEMORY button once. The last reading appears. Press again to scroll through previous readings.
2. Average Value: After displaying the last three stored readings, the display shows "AVG" and the average of those three readings.
3. Clear Memory: To delete all memory, press and hold the MEMORY button while turning on the device (press START/STOP). "CLr" will appear, then all data is erased.

Note: Memory is maintained when batteries are replaced if done within 2 minutes.
