My set-top box changes channels itself

UHF remotes enable you to control your set-top box from a long distance. For instances where your channel changes on its own, it might another remote (e.g. neighbour’s) communicating with your set-top box.

The method of troubleshooting this issue will vary by set-top box and remote. Check Remote Control Overview for your remote’s user manual.

For set-top box that has good line of sight to your remote.

Disabling UHF will prevent external signals from reaching your set-top box. You will however have to point the remote directly at the set-top box when using it.

To disable UHF:

• If your set-top box has a small metal antenna with a ball at the end, simply remove it.
• If it does not have an antenna, change the UHF settings by going to Preference > Hardware Settings.

For set-top box that does not have a good line of sight to your remote (hidden in a cabinet, behind the TV, etc.).

Troubleshooting steps:

1. Move the set-top box temporarily where it will have a line of sight.
   • You can also move closer to the set-top box while troubleshooting.
2. Disable the UHF using the steps above.
3. Change the remote address.
4. Once complete, you can re-enable UHF and place the set-top box back where it was before.

This will maintain the UHF communication between the remote and set-top box; tying them exclusively to each other.
