Setup Guide
1. Connecting the Transmitting Base to Your TV
Audio Connection Options:
- Optical Digital Audio (Recommended for Smart TVs): Connect the included Optical Cable from your TV's "Optical Out" port to the "Optical In" port on the Transmitting Base. Ensure your TV's audio output setting is configured to PCM for compatibility with built-in TV applications (e.g., Netflix, Hulu).
- 3.5mm Audio Jack: Connect the 3.5mm end of the 3.5mm to RCA cable to your TV's headphone or audio out jack. Connect the RCA ends to the corresponding RCA input on the Transmitting Base.
- RCA Audio Output: If your TV has dedicated RCA audio output jacks (typically red and white), connect the RCA ends of the 3.5mm to RCA cable to your TV's RCA output and the 3.5mm end to the Transmitting Base. If your TV's RCA outputs are already in use, utilize the provided RCA splitter to share the connection.
2. Powering the Transmitting Base:
Connect one of the provided power adapters to the Transmitting Base and plug it into a standard wall outlet. The Power indicator on the base will illuminate, confirming it is receiving power.
Operating Instructions
1. Charging the Wireless Speaker
Place the Wireless Speaker onto the Transmitting Base. The "LOW BATT/CHARGING" indicator on the speaker will light up, indicating it is charging. A full charge takes approximately 3 hours and provides up to 8 hours of continuous use at mid-volume.
Alternatively, you can charge the speaker directly using the second power adapter by connecting it to the USB-C port on the speaker and plugging it into a wall outlet. Important: Use only the provided 5V 2A power adapters to prevent potential damage to the device.

Rotate the large central knob on the Wireless Speaker to adjust the audio volume to your preferred listening level.
4. Private Listening with Earbuds
For private listening, plug the included wired earbuds into the 3.5mm headphone jack located on the Wireless Speaker. The speaker's internal sound will automatically mute, and audio will be directed to the earbuds.

- Cleaning: Wipe the speaker and base with a soft, dry cloth. Avoid using liquid cleaners, abrasive materials, or solvents, as these can damage the finish or internal components.
- Storage: When not in use for extended periods, store the device in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: To prolong the internal battery's lifespan, avoid fully discharging the speaker frequently. It is recommended to charge it regularly, even if not completely depleted.
Troubleshooting
If you encounter any issues with your SEREONIC PRO Wireless TV Speakers, please refer to the following common problems and solutions:
