4. Main Unit Problems
Q1: After power-on, the ECG stays on the logo screen and doesn't open the main screen. I have
restarted the machine several times, but there is no better change.
A1: The reason for this problem might be: there is a key pressed down, without springing up.
Find that key, and make it spring up, the problem should be solved.
Q2: I was doing the examination when the machine suddenly gave out a sound and displayed the
hint Lead Off. What should I do?
A2: The corresponding electrodes are not connected well. Please find out which lead is off by
checking the Lead Name area on the main screen (please refer to Section 3.4, "About the
main screen"). The lead whose name is highlighted is off. Please check whether the
corresponding electrode of the lead is 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 takes effect, please contact the manufacturer or the
local distributor for further disposal.
