Topfield 5800/Troubleshooting/Install
When the Toppy starts up with no channels (out of the box, or after a Factory Reset) it will only show the Main Menu. In this situation you to go to the Service Search item of the Installation Menu and perform a search for channels. You can use the slow Auto search, or a much better quick manual scan.
If you have TAPs installed you might need to prevent them loading in this state. To do this, press and hold down the '0' button on the remote while the Toppy is starting up.
If you are preparing to do a Factory Reset then either do a channel scan immediately afterwards (before rebooting), or disable all TAPs first using something like TAPCommander.
