Cuff: Marked with artery index line (△) for proper positioning on arm.

Initial Setup

Before first use, install batteries and set date/time.

1. Open battery compartment on rear; insert 4 AA batteries observing polarity.
2. Close compartment; device may turn on automatically.
3. Set date and time: Press and hold MEMORY button for 3 seconds until display flashes. Use START/STOP to adjust values, MEMORY to confirm and move to next setting.
4. Connect cuff: Plug cuff tube into connector port until it clicks.

CAUTION! Use only recommended batteries. Remove batteries if device will not be used for an extended period.

Taking a Measurement

For accurate results, rest for 5 minutes before measuring. Avoid eating, drinking caffeine, smoking, or exercising 30 minutes prior.

1. Sit comfortably with back supported, feet flat on floor, and arm resting on a table at heart level.
2. Wrap cuff around bare upper arm (1-2 cm above elbow). Ensure artery marker (△) aligns with brachial artery.
3. Cuff should be snug but not tight; you should fit one finger underneath.
4. Press USER button to select your profile (U1 or U2).
5. Press START/STOP button. Device will inflate automatically.
6. Remain still and quiet until measurement is complete and cuff deflates.
7. Results display with systolic, diastolic, pulse, and any detection symbols.
8. Device automatically stores reading and powers off after 1 minute.

Tip: Take measurements at the same time each day for consistent tracking.

Understanding Results

The display shows systolic pressure (top number), diastolic pressure (middle number), and pulse rate (bottom number).

Normal Ranges (Adults): Systolic: <120 mmHg, Diastolic: <80 mmHg. Consult your doctor for personal targets.

Memory Function

Stores up to 60 readings per user (U1 and U2).

1. To recall memory: Press MEMORY button. Display shows average of last 3 readings.
2. Press MEMORY again to scroll through individual stored readings with date/time.
3. To clear memory for a user: While in memory mode for that user, press and hold START/STOP for 5 seconds until display clears.

Note: Memory is retained when batteries are replaced if done quickly (within 2 minutes).

Care & Maintenance

Unplug cuff and remove batteries before cleaning. Use a soft, dry cloth to wipe the device and cuff. Do not use alcohol, solvents, or abrasive cleaners.
