Sit quietly for 5 minutes in a chair with back support.
Place cuff on left arm (or as advised by doctor) at heart level.
Press START/STOP button; cuff inflates automatically.
Remain still and quiet during inflation and deflation.
Read results on display; note systolic, diastolic, pulse, and any symbols.
To turn off, press START/STOP again or wait for auto shut-off.

WARNING! Do not move or talk during measurement. Ensure cuff is not over clothing.

Understanding Results

Display shows systolic pressure (top number), diastolic pressure (bottom number), pulse rate, and WHO indicator.

Reading	Normal Range	WHO Indicator Color
Systolic	<120 mmHg	Green (Optimal)
Diastolic	<80 mmHg	Green (Optimal)
Systolic	120-139 mmHg	Yellow (Normal)
Diastolic	80-89 mmHg	Yellow (Normal)
Systolic	≥140 mmHg	Red (High)
Diastolic	≥90 mmHg	Red (High)

Irregular Heartbeat Symbol: If this icon appears, measurement may be affected by arrhythmia; repeat measurement. If persistent, consult physician.

Memory Function

Stores readings for two users separately.

Select User: Press User button to choose User 1 or User 2 icon.
Store Reading: After measurement, reading is automatically saved to selected user.
