Replace batteries when the remote's response becomes sluggish or it stops functioning. Always replace both batteries at the same time with new ones of the same type (AAA). Do not mix old and new batteries, or different types of batteries. Remove batteries if the remote will not be used for an extended period to prevent leakage.

- Distance: Ensure you are within the effective operating range of the remote control.
- Interference: Strong light sources (e.g., direct sunlight, fluorescent lights) can sometimes interfere with infrared signals. Try operating the remote in a different lighting condition.
6.2 Specific Functions Not Working
