Maintenance
Cleaning:
To clean the remote control, wipe it gently with a soft, dry cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the remote's surface or internal components.

Replace batteries when the remote's performance degrades or the display becomes dim. Always replace both batteries at the same time with new ones of the same type (AAA). Remove batteries if the remote will not be used for an extended period to prevent leakage.
Troubleshooting
- Remote not responding: Check if the batteries are inserted correctly with the correct polarity. Replace old batteries with new ones. Ensure there is a clear line of sight between the remote and the air conditioner's receiver.
