Maintenance
Cleaning
To clean your remote control, gently wipe the surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the remote's finish or internal components.
Battery Replacement
Replace batteries when the remote's response becomes sluggish or stops working. Always replace both batteries at the same time with new AA alkaline batteries. Do not mix old and new batteries, or different types of batteries, as this can lead to leakage or malfunction.
Storage
If the remote control will not be used for an extended period, it is recommended to remove the batteries to prevent potential leakage and damage. Store the remote in a cool, dry place away from direct sunlight and extreme temperatures.
