Maintenance
Battery Replacement
Replace batteries when the remote's response becomes sluggish or it stops functioning. Always use new AAA alkaline batteries. Do not mix old and new batteries, or different types of batteries.
Cleaning
To clean the remote, gently wipe its surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the remote's electronics or finish.
Troubleshooting
- Remote not responding:
- Check battery orientation and ensure they are fresh.
- Re-pair the remote with your TV following the pairing instructions in the Setup section.
- Ensure there are no obstructions between the remote and the TV's IR receiver.
- Voice function not working:
- Ensure the remote is properly paired via Bluetooth. Voice control requires Bluetooth connection.
- Verify that the VOICE CONTROL setting in your TV's menu is set to "active".
- Confirm that only this remote is paired with your TV, as some TVs support only one voice remote at a time.
- Buttons feel stiff:
Upon initial use, some buttons may feel slightly stiff. This is normal for a new remote and will soften with regular use over a few days.
- Back cover not flush:
The design of the back cover may not sit perfectly flush with the other part of the remote. This is a factory design characteristic and not a defect. It does not affect the remote's functionality.
