6. Operation
6.1. Power On/Off
The switcher powers on automatically when connected to power. Use the ON/OFF button on the remote control or the 'SWITCH' button on the device to toggle power.
6.2. Switching Input Sources
You can switch between the three input sources (IN1, IN2, IN3) using either the IR remote control or the 'SWITCH' button on the device.
- Using the Remote Control: Press the '1', '2', or '3' buttons on the IR remote control to select the corresponding input source. The remote control has a working range of up to 16 feet.
- Using the Manual Switch: Press the 'SWITCH' button on the device to cycle through the input sources.
6.3. Input Indicators
The LED indicators (1, 2, 3) on the device will illuminate to show which input source is currently active.

7. Maintenance
Regularly check all cable connections to ensure they are secure. Keep the device in a dry, dust-free environment. Clean the exterior with a soft, dry cloth. Do not use liquid cleaners or solvents, as they may damage the device.
8. Troubleshooting
8.1. No Audio Output
- Ensure all optical cables are securely connected to both the source devices, the switcher, and the receiving devices.
- Verify that the correct input source is selected on the switcher (check LED indicators).
- Confirm that the audio format from your source device is supported by the switcher and your receiving device (LPCM2.0/DTS/Dolby-AC3).
- Check if the power adapter is correctly connected and providing power to the switcher.
- Ensure your receiving device (soundbar, amplifier) is set to the correct optical input.
8.2. Remote Control Not Working
- Ensure batteries are correctly inserted into the remote control (note: batteries are not included with the product).
- Check if there are any obstructions between the remote control and the IR receiver on the switcher.
- Ensure you are within the working range of the remote control (up to 16 feet).
8.3. Poor Audio Quality
- Ensure you are using high-quality optical fiber cables with loss less than 0.2Db/m.
- Check for any kinks or damage in the optical cables.
9. User Tips
No specific user tips are available at this time. For optimal performance, ensure all connections are firm and use high-quality optical cables.
