Back: Battery compartment, air release valve.

Before First Use

Prepare the device for initial measurement.

Insert Batteries: Open compartment on back, insert 4 AA batteries as indicated.
Apply Cuff: Sit quietly for 5 minutes. Expose left upper arm (recommended). Place cuff with tube facing down and artery mark over brachial artery.

Taking a Measurement

Follow these steps for an accurate reading.

Press START/STOP button. All display symbols will appear briefly.
Cuff will inflate automatically. Remain still and do not flex arm.
As cuff deflates, measurement values will appear.
When measurement is complete, cuff deflates fully. Systolic, diastolic, and pulse readings are displayed.
To view last reading, press MEMORY button.
Device turns off automatically after 1 minute.

WARNING! Do not inflate cuff manually. If uncomfortable, press START/STOP to stop.

Understanding the Display

Reading example: 120/80 (65).

Systolic Pressure: Top number (e.g., 120 mmHg).
Diastolic Pressure: Bottom number (e.g., 80 mmHg).
Pulse Rate: Number in parentheses (e.g., 65 beats per minute).
Hypertension Indicator: Heart symbol flashes if systolic ≥135 or diastolic ≥85.
Irregular Heartbeat Symbol: Appears if an irregular rhythm is detected.
Memory Icon: "M" appears when last reading is recalled.
Battery Icon: Flashes when batteries are low.

Memory Function

Stores the last measurement only.

After taking a reading, press MEMORY button to recall it.
The "M" icon appears with the stored values.
Taking a new measurement overwrites the previous memory.
Memory is cleared when batteries are removed.
