1. Open the battery compartment cover on the back of the device.
2. Insert two AAA batteries according to the polarity indicators (+ and -) inside the compartment.
3. Close the battery compartment cover securely.

Note: When the low battery symbol appears on the display, replace both batteries with new ones. Replacing batteries will erase stored date and time settings, requiring them to be reset.

3.2 Setting Date and Time

Accurate date and time settings are crucial for tracking your readings. After battery installation or replacement, you will need to set the date and time:

1. With the device off, press and hold the 'SET' button (often labeled with a gear icon or 'S') for a few seconds until the year starts flashing.
2. Press the 'M' button to adjust the year.
3. Press 'SET' again to confirm the year and move to the month setting.
4. Repeat steps 2 and 3 for month, day, hour, and minute.
5. Once all settings are confirmed, the device will exit the setting mode.

4. Operating Instructions

4.1 Proper Cuff Placement

Correct cuff placement is essential for accurate readings. The adjustable wrist cuff fits wrist circumferences from 4.92 to 8.27 inches (12.5 to 21 cm).

1. Ensure your wrist is bare; remove any clothing or jewelry.
2. Wrap the cuff on your left wrist with the monitor facing up and your palm open.
3. Position the cuff approximately 0.2-0.4 inches (0.5-1 cm) below your wrist joint.
4. Fasten the cuff snugly but not too tightly. There should be enough space to insert one finger between the cuff and your wrist.

4.2 Measurement Procedure

Follow these steps to take a blood pressure measurement:

1. Sit in a comfortable position with your back supported.
2. Place your wrist at the same level as your heart. Relax and remain still.
3. Press the 'START' button. The cuff will automatically inflate and then slowly deflate.
4. Remain still and do not talk during the measurement.
5. Once the measurement is complete, your Systolic pressure (SYS), Diastolic pressure (DIA), and Pulse rate will be displayed on the screen.
6. The device will automatically store the reading in its memory.

4.3 Understanding Your Readings

The display shows three main values:

• SYS (Systolic Pressure): The top number, indicating the pressure in your arteries when your heart beats.
• DIA (Diastolic Pressure): The bottom number, indicating the pressure in your arteries between beats.
• Pulse /min: Your heart rate, or the number of times your heart beats per minute.

An 'Irregular Heart Beat Symbol' will appear if an irregular heartbeat is detected during the measurement. Consult your doctor if this symbol appears frequently.

4.4 Memory Function

The monitor stores up to 60 readings with a time and date stamp. It also displays the average of the last three consecutive records for reference.

• To view stored readings, press the 'M' button when the device is off. Each press will cycle through the stored measurements.
• The average of the last three readings will be displayed first.
• To clear the memory, consult the specific instructions in the full manual, as this process can vary.
