Taking a Measurement

Follow these steps for an accurate reading.

Remain still and seated for 5 minutes before measuring.
Wrap the cuff correctly on your left upper arm.
Press the START/STOP button. The monitor will inflate automatically.
Remain still and quiet during inflation and measurement. Do not move your arm or talk.
The cuff will deflate automatically. Your systolic, diastolic, and pulse readings will appear on the display.
The reading is automatically stored in memory.
To turn off the unit, press the START/STOP button again, or it will turn off automatically after 1 minute.

Tip: For the most accurate results, take measurements at the same time each day, before meals or medication.

Understanding Your Readings

The monitor displays systolic pressure (top number), diastolic pressure (bottom number), and pulse rate.

WHO Classification Bar: Appears on the right side of the display indicating where your systolic reading falls (Normal, High-Normal, Mild Hypertension, etc.).
Hypertension Symbol: A heart icon flashes if your systolic reading is 135 mmHg or higher, or diastolic is 85 mmHg or higher.
Irregular Heartbeat Symbol: A heart with a plus icon appears if an irregular rhythm is detected during measurement.
Average Reading: If you take 3 readings within 10 minutes, the average of the last 3 will be displayed after the third reading.

Note: A single high reading does not necessarily indicate hypertension. Consult your doctor for a proper diagnosis.

Memory Function

The device stores the last 100 readings with date and time.

To view memory: Press the MEMORY button. The most recent reading appears.
Scroll through readings: Press the MEMORY button repeatedly to cycle through stored readings in reverse chronological order.
Memory full: When the memory is full (100 readings), the oldest reading is automatically deleted when a new one is stored.
Clear all memory: To delete all readings, press and hold the MEMORY button for more than 3 seconds while in memory mode. "CLr" will appear, then all data will be erased.

WARNING! Clearing memory is irreversible. Ensure you have recorded any needed readings before clearing.
