Tip: Take measurements at same time daily for consistent tracking.

Understanding the Display

LCD shows: Systolic pressure (upper number), Diastolic pressure (lower number), Pulse rate, Date/Time, Memory number, Hypertension indicator (if systolic ≥135 or diastolic ≥85), Irregular heartbeat symbol (if detected), Body movement symbol (if detected), Low battery icon, Cuff wrap guide.

Memory Function

Stores last 14 readings with date and time.

View memory: Press Memory button to scroll through stored readings.
Clear memory: Press and hold Memory button for 5 seconds until "0" appears.
