Side/Back: Cuff Socket, AC Adapter Socket, Battery Compartment (requires 4xAA batteries).

Cuff: Marked with ARTERY index line. Ensure this line aligns with brachial artery on inner arm.

First-Time Setup

Before first use: Install batteries or connect AC adapter, set date/time, and select user.

Power Source: Insert 4xAA batteries (observe polarity) OR plug in AC adapter to monitor and wall outlet.
Set Date/Time: Press and hold DATE/TIME button for 3 seconds. Use START/STOP to adjust values, MEMORY to confirm and move to next setting.
Select User: Press USER button to toggle between User 1 and User 2. Corresponding icon appears on display.
Cuff Connection: Plug cuff tube firmly into socket on side of monitor.

CAUTION! Do not mix old and new batteries. Remove batteries if device will not be used for extended period.

Taking a Measurement

For accurate results, rest for 5 minutes before measuring. Sit in a quiet place with back supported and feet flat on floor.

Apply cuff on bare upper arm. Cuff edge should be 1-2 cm above elbow. ARTERY line should align with inner arm's artery.
Secure cuff snugly but not too tight (should fit one finger underneath).
Rest arm on table with cuff at heart level. Palm facing upward, relax hand.
Press START/STOP button. Monitor will inflate automatically.
Remain still and quiet during inflation and measurement. Do not move arm or talk.
Monitor will deflate and display results (Systolic, Diastolic, Pulse).
Results are automatically saved to selected user's memory.
To turn off, press START/STOP again or wait for auto power-off (1 minute).

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

Understanding Your Results

The display shows three main values and indicators:

Systolic Pressure: Top number (e.g., 120 mmHg) - pressure when heart beats.
Diastolic Pressure: Bottom number (e.g., 80 mmHg) - pressure when heart rests.
Pulse Rate: Beats per minute (e.g., 72 bpm).

WHO Indicator Bar: Color-coded bar on right side of display: Green (Optimal: <120/80), Yellow (Normal: 120-129/80-84), Orange (High Normal: 130-139/85-89), Red (Hypertension: ≥140/90).

Symbols: Irregular Heartbeat symbol ( ) appears if irregular pulse detected during measurement. Body Movement symbol ( ) appears if excessive movement detected.

Note: A single high reading is not necessarily cause for alarm. Consult your physician if consistently high or if symptoms occur.

Memory Function

The device stores 99 readings for each of two users, with date and time stamp.

View Memory: Press MEMORY button. Display shows most recent reading with memory icon and sequence number.
Scroll Through Memory: Press MEMORY repeatedly to scroll through all stored readings for current user.
Switch User Memory: Press USER button to select other user, then press MEMORY to view their readings.
Average Value: When 3 readings are taken within 10 minutes, the average of these 3 is displayed automatically after the third measurement.
Clear Memory: To delete all readings for current user: With device off, press and hold MEMORY and USER buttons simultaneously for 5 seconds until "CLr" appears.

Note: Memory is maintained when batteries are replaced if done within 3 minutes.
