You have two remote controls. One for the TV and the other for the Chromecast (used as a TV box).

The Chromecast remote control also directly controls the TV (it turns on both devices at the same time).

You can also send videos from your smartphone to the Chromecast and thus to the TV (YouTube, Netflix, etc.) if you want to use your accounts and services.

You have free access to Netflix and Amazon Prime via the Chromecast. Use the 'Guest' account.

Netflix

Prime Video

To watch TV, use the TV remote to switch to the TNT channels (change the input source).

If a remote control no longer works, new batteries can be found in the cupboard of the electrical meter.
