Stim Switch User Manual Troubleshooting I live in a country with 220 V power, but the back of the Stim Switch Control Module says 110 V. You can change the power supply voltage rating by flipping open the panel above the plug on the back of the module and rotating the wheel so that it says 220 V. - Page 23 Check that the Headstage Module is recognized. The Headstage Module LED for each bank that is in use on the Stim Switch Control Module should be green. If it is red try disconnecting the Stim Switch cable and ensuring that both ends are plugged into the Headstage Module and the Control Module correctly.
