Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display when powered on | Batteries are dead or incorrectly inserted. | Replace batteries or check polarity. |
| Inconsistent readings | Incorrect cuff placement, movement during measurement, or improper posture. | Ensure cuff is correctly placed 1/2 inch from hand, remain still, and keep wrist at heart level. Take multiple readings. |
| "E" or Error message on display | Cuff not inflated properly, excessive movement, or technical malfunction. | Re-apply cuff, ensure no movement, or contact customer support if problem persists. |
| Irregular Heartbeat (IR) symbol appears frequently | Indicates detection of irregular heartbeats. | This is a feature, not a malfunction. Consult your physician if this symbol appears frequently. |
