Replace batteries when the remote control's response becomes sluggish or stops working. Always replace both batteries simultaneously with new AAA alkaline batteries. Do not mix old and new batteries, or different types of batteries.
Cleaning
To clean the remote control, gently wipe it 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.
Storage
Store the remote control in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. If the remote will not be used for an extended period, it is advisable to remove the batteries to prevent leakage.
Troubleshooting

- Ensure batteries are inserted correctly with the correct polarity (+/-).
- Replace old batteries with new AAA alkaline batteries.
- Ensure there are no obstructions between the remote control and the sound bar's infrared receiver.
- Confirm you are within the effective range of the sound bar's IR receiver.
- Specific Buttons Not Working:
- Verify that the sound bar is powered on and in the correct operating mode.
