5. Operating Instructions

5.1 Basic Operation

Once the TX and RX units are powered on and connected, the video and audio from your source device will be wirelessly transmitted to the display connected to the RX unit. If you have connected a local display to the TX unit's loopout port, the content will also be shown there.

6. Maintenance

To ensure the longevity and optimal performance of your YEHUA R15Y Wireless HDMI system, please follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the units. Avoid using liquid or aerosol cleaners, as they may damage the casing or internal components.
• Environment: Operate the device in a well-ventilated area. Avoid exposing the units to extreme temperatures, direct sunlight, high humidity, or dusty environments.
• Power: Use only the provided power adapters. Disconnect power during lightning storms or when unused for long periods.
• Handling: Handle the units with care. Avoid dropping or subjecting them to strong impacts.

7. Troubleshooting

If you encounter issues with your YEHUA R15Y system, please refer to the following troubleshooting steps:

1. No Signal on Display:
   • Ensure both TX and RX units are powered on and their indicator lights are active.
   • Verify all HDMI cables are securely connected to both the source and display devices, and to the TX/RX units.
   • Check that the display is set to the correct HDMI input source.
   • Try connecting the source device directly to the display with an HDMI cable to confirm the source and display are working correctly.
   • Reduce the distance between the TX and RX units and ensure there are no major obstructions (e.g., thick walls, metal objects) that could interfere with the wireless signal.
2. Poor Video Quality or Intermittent Signal:
   • Ensure antennas are securely attached and oriented for optimal signal reception.
   • Minimize wireless interference from other 5GHz/2.4GHz devices (e.g., Wi-Fi routers, cordless phones).
   • Check the resolution settings of your source device. While the system supports 1080P, some older displays might require lower resolutions.
   • Ensure the power adapters are providing stable power to both units.
3. IR Remote Control Not Working:
   • Ensure the IR Blaster cable is securely connected to the TX unit and its head is positioned directly in front of the source device's IR sensor.
   • Ensure the IR Receiver cable is securely connected to the RX unit and is positioned to receive signals from your remote control.
   • Check the batteries in your remote control.
4. Audio Issues:
   • Verify that the audio settings on your source device and display are correctly configured.
   • Ensure the HDMI cables are fully inserted, as loose connections can affect audio transmission.
