Please, i need a help. I have esaote mylab20plus. The measurement button, doppler button, and others are not responding when i press it but it makes sound showing it may not be mechanical fault. I couldn't find obstetrics parameters also. But i can scan but can not measure or use doppler. Only the depth, gain, freez, 2b, and M mode are responding. Please what could be the issue with the mahcine.
