The unit does not power on, or the battery charge indicator does not light up.
If you are not an experienced biomedical technician, – ECG devices involve patient safety (leakage current, defibrillation protection). Use the above only as a reference for troubleshooting under supervision.
If the cable connecting the touch screen to the main board is defective or loose, the screen will not respond. If the cable is intact but the "touch position is invalid," the touch screen may need to be calibrated from the internal settings of the ECG machine. carewell ecg 1101 service manual fix
