To set the freezer temperature on the Daewoo Electronics FR-540N refrigerator, press the freezer temperature button. The display will cycle through different stages in the following order:
1. R1-sensor temperature
2. D-sensor temperature
3. F-sensor temperature
4. Error code

If no button is pressed for 8 minutes, the display will return to normal automatically.
