   * Adjust MCFD threshold:
+      * Open configuration file **MCFD16.tcl** in **/user/s800/operations/daq/usb/Configs**
       * The OBJ signal feeding this module is not patched out to data U6
       * The OBJ signal from MCFD-16 module goes to the Mesytec MTDC32 module and scaler (channel OBJ.MCFD.Scint)
-      * Adjust CFD threshold looking at scalers. The ratio of OBJ to XFP scaler rates (channels OBJ.MCFD.Scint and XFP.MCFD.Scint) should reflect the transmission of the cocktail beam
+      * Make sure that the threshold of the XFP MCFD channel is reasonable. Rates in scaler channels XFP.Scint and XFP.MCFD.Scint should be comparable
+      * Adjust MCFD OBJ threshold looking at scalers. The ratio of OBJ to XFP scaler rates (channels OBJ.MCFD.Scint and XFP.MCFD.Scint) should reflect the transmission of the cocktail beam
+      * Save new threshold in configuration file **MCFD16.tcl**
