Overview

If your channels are changing on their own, the set-top box is probably being affected by UHF interference.

Remote control interference: UHF issues

UHF (Ultra High Frequency) remotes enable you to control your set-top box from a long distance. As a result, there may be instances where another remote control impacts your television. For instances where your channel changes on its own, it might another remote (e.g. neighbour’s) communicating with your set-top box.

There are two ways to fix this issue:

  • Disable UHF
  • Change the remote address

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

How to disable UHF

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.

Changing Remote Control Address

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.
