Setup and Connection
This HDMI cable is designed for simple plug-and-play operation. Follow these steps to connect your devices:

- Connect First End: Insert one end of the J-Tech Digital HDMI cable firmly into the HDMI output port of your source device.
- Connect Second End: Insert the other end of the HDMI cable firmly into the HDMI input port of your display device.

Operating Instructions
Once connected, the J-Tech Digital HDMI cable facilitates the transmission of high-definition audio and video signals between your devices. No additional configuration is typically required for the cable itself.
- Automatic Resolution Detection: When connecting two devices with different HDMI standards, the cable will automatically facilitate the best available connection and resolution (e.g., 4K@60Hz if both devices support HDMI 2.0).
- Audio Return Channel (ARC): If your display and audio receiver both support ARC, this cable can transmit audio from your TV back to your audio system, simplifying your setup by eliminating the need for a separate audio cable. Ensure ARC is enabled on both devices.
- HDR Support: The cable supports High Dynamic Range (HDR) for enhanced contrast and color if your connected devices and content also support HDR.
Maintenance and Care
To ensure the longevity and optimal performance of your J-Tech Digital HDMI cable, please follow these maintenance guidelines:
- Handle with Care: Avoid excessive bending, twisting, or pulling of the cable, especially near the connectors.
- Clean Connectors: If connectors appear dusty, gently wipe them with a dry, lint-free cloth. Do not use liquid cleaners.
- Storage: When not in use, store the cable in a cool, dry place, ideally coiled loosely to prevent kinks.
- Avoid Extreme Conditions: Do not expose the cable to extreme temperatures, direct sunlight, or high humidity.

| Flickering/Intermittent Signal | Cable interference, damaged cable, resolution mismatch. | Check for strong electromagnetic interference sources. Inspect the cable for visible damage. Ensure your source and display are set to compatible resolutions. |
| No Audio (Picture is fine) | Audio settings on devices, ARC not enabled. | Check audio output settings on the source device and input settings on the display/receiver. Ensure ARC is enabled on both devices if using that feature. |
