Maintenance
Battery Replacement
When the remote control's display becomes dim or its operating range decreases, it is time to replace the batteries. Always replace both batteries with new AAA alkaline batteries. Do not mix old and new batteries, or different types of batteries.
Cleaning
Wipe the remote control with a soft, dry cloth. Do not use liquid cleaners, abrasive cleaners, or chemical sprays, as these can damage the remote's surface or internal components.
Storage
If the remote control will not be used for an extended period, remove the batteries to prevent leakage and potential damage.
Troubleshooting
- Remote not responding:
- Check if the batteries are correctly installed and have sufficient power. Replace if necessary.
- Ensure there are no obstructions between the remote control and the air conditioner's receiver.
- Make sure you are within the effective operating range (typically 8 meters or 26 feet) and pointing the remote directly at the air conditioner.
- Display is dim or blank:
- Replace the batteries.
- Air conditioner responds intermittently:
- This could indicate low battery power or interference. Try replacing batteries and ensuring a clear line of sight.
