Maintenance
Cleaning
To clean the remote control, gently wipe its surface with a soft, dry cloth. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the remote's finish or internal components.
Battery Replacement and Storage
If the remote control's display becomes dim, or its responsiveness decreases, it is time to replace the batteries. Always replace both AAA batteries at the same time with new ones. When storing the remote control for extended periods (e.g., during off-season), remove the batteries to prevent potential leakage and damage to the device.
