1. Įvadas
The BlueRigger HDMI CEC Less Adapter is designed to resolve common issues caused by HDMI Consumer Electronics Control (CEC) signals. CEC allows devices connected via HDMI to communicate and control each other, but sometimes this functionality can lead to unintended behaviors, such as devices turning on or off unexpectedly, or audio routing problems.
This adapter effectively blocks the CEC signal (specifically Pin 13) while allowing all other HDMI signals, including 4K UHD video, Audio Return Channel (ARC), and Ethernet, to pass through unimpeded. This ensures stable and reliable performance for your home entertainment system.

2. Sąranka ir diegimas
Installing the BlueRigger HDMI CEC Less Adapter is a straightforward plug-and-play process. Follow these guidelines for optimal performance:
- Identify the interfering device: Determine which source device (e.g., game console, streaming stick, Blu-ray player) is causing unwanted CEC behavior.
- Prijunkite adapterį: Insert the male end of the BlueRigger HDMI CEC Less Adapter into the HDMI output port of the interfering source device.
- Connect the HDMI cable: Plug your existing HDMI cable from the source device into the female port of the CEC adapter.
- Connect to display: Connect the other end of the HDMI cable to your TV or A/V receiver's input port.
Important Note: DO NOT use the CEC Adapter on the ARC/eARC port of your TV or on the HDMI connection to your soundbar. This adapter is intended for use with other input devices (e.g., PS5, Apple TV, Nintendo Switch, Xbox, Cable TV) to prevent them from interfering with your ARC/soundbar connection.

4. Problemų sprendimas
If you experience issues after installing the BlueRigger HDMI CEC Less Adapter, consider the following common scenarios and solutions:
- Issue: TV or sound system turns on/off unexpectedly.
Sprendimas: This is a classic symptom of unwanted CEC signals. Ensure the adapter is placed on the HDMI output of the device causing the interference, and ne on the ARC/eARC port of your TV or soundbar. - Issue: Audio problems with soundbar (e.g., no sound, switching inputs).
Sprendimas: Confirm that the CEC adapter is not connected to the HDMI ARC/eARC port on your TV or soundbar. The adapter is designed to block CEC from source devices, not to manage ARC/eARC communication. - Issue: Remote control commands are not working for a specific device.
Sprendimas: If you intend for a device to be controlled by your TV's remote via CEC, do not use the adapter on that device's HDMI connection. The adapter will block all CEC commands to and from that device. - Issue: No video or audio signal after installation.
Sprendimas: Double-check all HDMI cable connections. Ensure the adapter is fully seated in the port. Test the HDMI cable and device without the adapter to rule out other component failures.
The adapter's function is to disable Pin 13, which is the CEC pin. If issues persist, verify that the problem is indeed related to CEC interference and not another aspect of your setup.
