Setup
Unpacking and Initial Inspection
- Carefully remove all components from the packaging.
- Inspect the device and accessories for any signs of damage. Do not use the device if it appears damaged.
- Ensure all listed components are present.

Connecting the Cuff
- Locate the air tube connector on the main unit.
- Firmly insert the air tube from the cuff into the connector. Ensure a secure fit to prevent air leakage during measurement.
Operating Instructions
Before Measurement
- Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes before measurement.
- Rest for at least 5 minutes before taking a measurement.
- Ensure the room temperature is comfortable.
Applying the Cuff
- Place the cuff on your bare upper arm, approximately 2-3 cm above the elbow joint.
- Ensure the air tube runs down the center of your arm in line with your middle finger.
- Wrap the cuff snugly around your arm, ensuring it is not too tight or too loose. The cuff size is 32 cm.
- Sit comfortably with your feet flat on the floor, and your arm resting on a table so the cuff is at heart level.

Taking a Measurement (Auscultatory Method)
This device uses the auscultatory method, requiring a stethoscope (not included) for listening to Korotkoff sounds.
- Press the "ON/OFF" button to power on the device. The digital display will activate.
- Place the stethoscope diaphragm over the brachial artery in the antecubital fossa (inner elbow).
- Close the air release valve on the inflation bulb.
- Inflate the cuff rapidly by squeezing the inflation bulb until the pressure displayed on the digital column is approximately 20-30 mmHg above the expected systolic pressure, or until the radial pulse is no longer palpable.
- Slowly open the air release valve to deflate the cuff at a rate of 2-3 mmHg per second.
- Listen carefully through the stethoscope:
- The pressure reading on the digital column when you first hear clear, tapping sounds (Korotkoff Phase I) is the Systolic Blood Pressure.
- Continue deflating. The pressure reading on the digital column when the sounds disappear completely (Korotkoff Phase V) is the Diastolic Blood Pressure.
- Note the systolic and diastolic readings from the digital display. The device also provides a digital readout for pulse rate.
- Fully deflate the cuff and remove it from your arm.
- Press the "ON/OFF" button again to turn off the device, or it will automatically power off after a period of inactivity.
Maintenance and Care
Cleaning
- Wipe the main unit and cuff with a soft, dry cloth.
- For more thorough cleaning, use a cloth lightly dampened with water or a mild disinfectant. Do not use abrasive cleaners or immerse the device in water.
- The device body is durable and chemical resistant.
Storage
- Store the device in a clean, dry place, away from direct sunlight, extreme temperatures, and humidity.
- Utilize the integrated cuff holder and grip for convenient storage and carrying.
- Product dimensions: 35 x 10 x 9 cm.
Calibration
It is recommended to have the sphygmomanometer calibrated periodically by qualified personnel to ensure accuracy. Consult your supplier or manufacturer for calibration services.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display when powered on. | Power source issue (if applicable, though this is manual). | Ensure the device is properly activated. If battery-operated (not specified, but common for digital displays), check batteries. |
| Cuff does not inflate or inflates slowly. | Air leakage from cuff or tubing; valve not closed. | Check all connections for tightness. Ensure the air release valve is fully closed before inflation. Inspect cuff and tubing for damage. |
| Inaccurate readings. | Improper cuff placement; patient movement; need for calibration. | Re-apply cuff correctly. Remain still during measurement. Consider professional calibration. |
| Difficulty hearing Korotkoff sounds. | Stethoscope placement; ambient noise; technique. | Ensure correct stethoscope placement. Measure in a quiet environment. Practice auscultation technique. |
If problems persist, contact customer support or a qualified service technician.
