Your Dr. Morepen BP One Blood Pressure Monitor BP-14 showing error 4 usually indicates a problem with cuff placement or inflation.

🩺 What Error 4 Likely Means

• This error commonly occurs if the cuff is not properly wrapped around the upper arm or is too loose.
• It may also appear if there is movement or talking during the measurement.
• Sometimes, a low battery can cause malfunction signals like this.

🏥 What You Can Do

• Ensure the cuff is positioned snugly on your upper arm, at heart level, without any twists.
• Remain still and quiet while the device measures your blood pressure.
• Check and replace the batteries if they are low or old.
• If the problem persists, try restarting the device or consult the user manual for specific troubleshooting steps.

🩺 When to See a Doctor

• If you cannot get accurate readings after troubleshooting, discuss this with a cardiologist or your primary care doctor to ensure your blood pressure is monitored correctly.
