+**Notes**:\n\
+* During scanning the number of muxes and services shown below should \
+increase; if not check the connection(s) to your device(s).\n\
+* The status tab (behind this wizard) will display signal information, \
+if you notice a lot of errors or the signal strength appears low this \
+usually indicates an issue with your antenna, satellite dish or cable.\n\
+* If you don't see any signal information at all but the number of \
+muxes and services is increasing the driver used by your device isn't \
+supplying signal information to Tvheadend, in most cases this isn't \
+an issue.\n\
