If the remote control's range decreases or it becomes unresponsive, replace both AAA batteries with new ones. Always replace both batteries at the same time and ensure correct polarity.
4.2 Cleaning
To clean the remote control, wipe it gently with a soft, dry cloth. Do not use liquid cleaners, abrasive pads, or chemical solvents, as these can damage the remote's surface or internal components.
4.3 Storage
When not in use for extended periods, remove the batteries to prevent leakage, which can damage the remote control.
