Device Overview

Front Panel: START/STOP Button, LCD Display, Memory Button (M), User Select Button (1/2).

Display Symbols: Systolic Pressure, Diastolic Pressure, Pulse Rate, Irregular Heartbeat Symbol, WHO Indicator Bar, User Icon, Memory Icon, Battery Icon, Date/Time.

Side/Back: Cuff Socket, AC Adapter Socket, Battery Compartment.

Cuff: Cloth cuff with metal D-Ring, air tube, and artery marker.

Initial Setup

Before first use, install batteries or connect AC adapter, set date/time, and apply cuff correctly.

Power: Insert 4 AA batteries into the compartment, observing polarity. Alternatively, plug the AC adapter into the socket and a wall outlet.
Date & Time: Press and hold the M button for 3 seconds. Use START/STOP to adjust values, M to confirm and move to next setting.
Cuff Application: Place cuff on bare upper arm. The artery marker (▷) should align with the brachial artery on the inner arm. Wrap cuff snugly, leaving 1-2 cm space at elbow. Secure with D-Ring.
Body Position: Sit comfortably with back supported, feet flat on floor. Rest arm on a table so cuff is at heart level.

Tip: Avoid eating, smoking, or exercising for 30 minutes before measurement.

Taking a Measurement

Follow these steps for an accurate reading.

Sit quietly for 5 minutes before measuring.
Apply the cuff correctly as described in Initial Setup.
Press the START/STOP button. The device will inflate automatically.
Remain still and do not talk during inflation and measurement.
The cuff will deflate automatically. Your systolic pressure, diastolic pressure, and pulse rate will display.
The reading will be stored automatically in memory for the selected user.
If the irregular heartbeat symbol appears, note it and consider repeating the measurement after a few minutes.
Press START/STOP to turn off the display, or it will power off automatically after 1 minute.

WARNING! Do not inflate the cuff when it is not wrapped around an arm.

Memory Function

The device stores up to 99 readings for each of two users (User 1 and User 2).

Select User: Before measurement, press the User Select button (1/2) to choose the correct user profile. The user icon (1 or 2) will show on display.
View Memory: Press the M button once to enter memory mode. The most recent reading for the selected user displays.
Scroll Memory: Press START/STOP to scroll through all stored readings for that user in reverse chronological order.
Exit Memory: Press M again or wait for automatic power-off to exit.
Clear Memory: To delete all readings for the current user, enter memory mode, then press and hold the M button for 5 seconds until 'CLr' appears.

Understanding Results

Reading Display: Shows systolic/diastolic pressure (mmHg) and pulse rate (BPM).

WHO Indicator: A color-coded bar on the right side of the display classifies your reading:

Green Zone: Normal (Systolic: <120, Diastolic: <80)
Yellow Zone: Mild Hypertension (Systolic: 120-139, Diastolic: 80-89)
Orange Zone: Moderate Hypertension (Systolic: 140-159, Diastolic: 90-99)
Red Zone: Severe Hypertension (Systolic: ≥160, Diastolic: ≥100)

Irregular Heartbeat Symbol: If this icon flashes during or after measurement, it detected a possible pulse irregularity. Take a second measurement after resting. If it appears frequently, consult your doctor.

Error Codes: 'Err' may appear for movement, cuff issues, or measurement failure. Ensure proper setup and repeat.

Care & Maintenance

Proper care ensures long device life and accurate readings.

Cleaning: Wipe the main unit and cuff with a soft, slightly damp cloth. Do not immerse in water or use harsh chemicals.
Storage: Store in the provided case in a cool, dry place. Do not store near heat sources or in direct sunlight.
