To maintain the remote control's appearance and functionality, clean it regularly:

Use a soft, dry cloth to wipe the surface of the remote control.
For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner.
Avoid using harsh chemicals, solvents, or abrasive cleaning materials, as these can damage the remote's finish or internal components.

Replace batteries when the remote control's response becomes sluggish or stops working. Always replace both batteries at the same time with new 1.5V AAA alkaline batteries. Do not mix old and new batteries, or different types of batteries.

Remove batteries if the remote control will not be used for an extended period to prevent battery leakage, which can damage the remote.
