Maintenance
Cleaning
To clean the remote, gently wipe its surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the remote's finish or internal components.
Battery Replacement
