Many receivers will automatically scan for channels and store them in memory. While all set-top boxes or digital TVs will differ slightly, most will require you to follow the same basic steps to retune.
1. Access ‘settings’ or ‘menu’ on your digital TV or set-top box remote control.
2. Once you’ve accessed the menu, find the ‘retune’ option. This may be found in ‘set up’, ‘channel’ or ‘store channels’. The name of the retune option may vary, it could be called ‘re-scan’, ‘replace’ or ‘store channels.’
3. Select the relevant option and allow your digital receiver to automatically identify digital TV channels.
