Due to an issue with the Noraxon VDD, deactivating EMG channels in Nexus is not supported and if attempted, a summation of all the channels is produced. If some sensors are not needed for the measurement, do not deactivate EMG channels in Nexus, but go to the Device Setup and turn them off by deleting the relevant EMG channels from the hardware list. To do this, complete the following steps.

1. Under **Local Vicon System**, expand **Devices** and select the **Ultium EMG**.
2. In the **Properties** below, click **Device Setup**.
3. In the **Hardware Setup** dialog, select the **Ultium** in the pane on the right and then click **Configure**.
4. In the next dialog, ensure the required sensors have been detected, select the ones you want to deactivate, click **Delete** and then click **OK**.
5. In the **Properties** pane for the relevant sensors, ensure the sensors remain selected in Nexus (ie, **do not clear Enabled**).
