5.2 Battery Replacement
Replace batteries when the remote's response becomes sluggish or it stops functioning. Always replace both AAA batteries simultaneously. Do not mix old and new batteries, or different types of batteries, as this can lead to leakage or improper operation. Dispose of used batteries according to local regulations.

When not in use for extended periods, it is recommended to remove the batteries to prevent potential leakage and damage to the remote control. Store the remote in a cool, dry place away from direct sunlight and extreme temperatures.

- Buttons not working:
- Clean the remote's surface, especially around the buttons, to remove any dirt or debris that might be preventing proper contact.
