Integrity of patient cable
，
including main cable and lead wires
，
should be checked regularly.
z
Knotting or crooking in closed angle will shorten the patient cable’s life, so please align the
patient cable and then collect the electrodes
z
Do not drag or twist the patient cable with excessive stress while using. Hold the connector
plugs instead of the cable when connect or disconnect the patient cable
z
Storing the lead wires in bigger wheel or swinging to avoid twisting or folding
z
Once damaged or aged patient cable has been found
，
replace it with new one immediately

Electrodes
z
Electrodes must be cleaned after use and be sure there is no remaining gel on them
z
Keep the suction ball of chest electrodes from sunshine and excessive temperature.
z
After long time use, the surface of electrodes will be oxidized because of erosion and other
causes. In this case, electrodes should be replaced to achieve high-quality ECG
6.4 Fuse Exchange
After AC power cord is well connected, if the AC power indicator light is off, the battery is working
and the AC power supply from the socket is normal, it might indicate the fuse is burned and need to
be replaced.
If the same model fuse is broken again after changing the fuse, it might indicate other failure
in the instrument. In this condition, turn off the machine and contact the maintenance agent
designated by ECGMAC.
7 Common Troubleshooting and Solution
7.1 Some Lead without Waveform Printout
This phenomenon might be caused by following issues:
z
When the patient cable is connected with patient, if the instrument start record before ECG
waveforms and data become stable, it might leads to data value saturation or overflow in the
baseline stable software.
