Understanding the Display

After measurement, the screen shows:

• Systolic Pressure (top number)
• Diastolic Pressure (bottom number)
• Pulse Rate (heart icon)
• Irregular Heartbeat Symbol (if detected)
• Hypertension Indicator (if reading is high)
• Memory Number where reading is stored
• Date and Time of reading

Note: An average reading icon appears if the last 3 readings (within 10 min) are averaged.

Memory Recall Function
