Universal Remote Control
The remote control runs on 2 x AAA batteries.
To insert or replace the batteries, follow these steps;
1) Push the catch on the battery cover upwards and pull the dark cover of the main part.
2) Carefully remove the old batteries (if applicable) then insert the new batteries, matching the + and – signs.
3) Once the batteries are in, put the cover back on, making sure the cover clicks into place.
When you're using the remote control, make sure:
- You point it straight at the Topfeld PVR box (or TV);
- There's nothing blocking the infrared receiver on the PVR box (or TV).
