Troubleshooting
If you are experiencing problems, try the solutions listed below.
Troubleshooting Checklist
Ask the patient to relax.
Make sure all cables are connected properly between the EMU40EX and the computer. If using a
LAN, make sure the hardware and software are configured correctly.
Make sure the patient electrodes are connected to the correct channels in the Breakout Box.
Make sure the patient electrodes fit properly into the Breakout Box (not loosely).
Make sure there are no apparent breaks in the patient electrode cables.
Are any of the electrodes touching? If so, they are causing a short circuit and will develop an
artifact.
Install a medical grade ground to make sure that your clinic has a properly grounded electrical
system.
Unplug any other devices on the same circuit such as printers, mechanical beds, vacuum
cleaners or other potential sources of interference.
Check the gain and timebase settings to ensure that they are appropriate for the current test. You
may also want to check the LFF, HFF, and Notch Filter settings. Choose Edit > Settings >
Montage. Right-click a cell in the appropriate column and select a value.
Turn the Base Unit off and on. This will reset the system.
Shut down for at least 10 seconds. Then set up the test again from the beginning. Shutting down
the computer and restarting sometimes solves the problem.
