4) Main Unit Problems
Q1: I was doing the examination when the machine suddenly gave out a sound and displayed the
hint Lead Off. What should I do?
A1: The leads are not connected well. Please check whether the electrodes are connected to the
patient skin well, and then make sure that the patient cable socket is connected to the patient
cable firmly.
If none of the above-mentioned measures take effect, please contact the manufacturer or the local
distributor for further disposal.
