5. Maintenance
5.1. Battery Replacement
Replace batteries when the remote's display becomes dim or the remote no longer responds to button presses. 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.
5.2. Cleaning
Wipe the remote control 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.
6. Troubleshooting
- Remote not responding:
- Check if batteries are inserted correctly with the correct polarity.
- Replace old batteries with new ones.
- Ensure there are no obstructions between the remote and the air conditioner unit.
- Confirm you are within the effective operating range.
- Some functions do not work:
As this is a replacement remote, it may not support all functions of your original air conditioner remote. This is normal. Focus on essential functions like power, mode, temperature, and fan speed.
- Display is dim or blank:
This indicates low battery power. Replace the batteries immediately.
If issues persist after following these steps, consider contacting the seller or referring to your air conditioner's original manual for specific unit troubleshooting.
