Upper Arm Blood Pressure Monitor error codes

**For most Upper Arm Blood Pressure Monitor errors, the immediate first step is to remove and reinsert the batteries, then re-apply the cuff correctly and try again.**

Here are common error codes and their quick troubleshooting tips:

* **”E1″ or “Cuff Err”**:
* **Meaning:** Cuff not applied correctly, too loose, too tight, or air leak.
* **Fix:** Ensure the cuff is snug against your bare upper arm, centered over the artery, and the hose is securely connected to the monitor. Check for kinks in the air tube.
* **”E2” or “Mov Err”**:
* **Meaning:** Excessive movement during measurement.
* **Fix:** Remain still and silent during the entire measurement process. Avoid talking or moving your arm, hand, or body.
* **”E3” or “Pressure Err” / “Pump Err”**:
* **Meaning:** Inability to inflate or deflate the cuff properly, potentially a blocked air tube or internal pump issue.
* **Fix:** Check that the air tube is not kinked or blocked. Ensure the cuff is not overtightened before inflation begins. If the problem persists, try a different cuff if you have one, or contact support.
* **”Lo” or “Lo Batt”**:
* **Meaning:** Low battery power.
* **Fix:** Replace all batteries with a fresh set (e.g., all new AA or AAA batteries). Do not mix old and new batteries.
* **”Hi” or “Over Err”**:
* **Meaning:** Blood pressure reading exceeds the device’s measurable range (e.g., >250-300 mmHg systolic).
* **Fix:** Remain calm and still, wait a few minutes, then try again. If it persists, consult a healthcare professional immediately.
* **”Err” (General)**:
* **Meaning:** Unspecified system error.
* **Fix:** Power cycle the device (remove and reinsert batteries), wait a few minutes, and try another measurement. If the error continues, the device may require professional service or replacement.
