3.4. Pairing (If Necessary)
The units are typically pre-paired. If re-pairing is needed, follow these steps:
- Ensure both TX and RX units are powered on.
- On the Receiver (RX) unit, press and hold the reset button for 7 seconds until a "Ready to Pair" message appears on the display.
- On the Transmitter (TX) unit, press and hold the button for 7 seconds. The TX unit will flash, then stay solid, then flash again for 5-20 seconds.
- A "Pairing" message and a QR code will appear on the display. The TX state will change to "V".
- Wait for 5-10 seconds for the pairing process to complete.

4. Operating Instructions
4.1. Basic Operation
Once the Transmitter and Receiver are connected and powered on, they will automatically establish a wireless connection. The HDMI signal from your source device will be transmitted to your display device. The system is designed for plug-and-play functionality, requiring no additional software or complex configurations.
4.2. Using the Loop Out Function
The HDMI local output on the Transmitter (TX) allows you to connect a local display. This is useful for monitoring the content being transmitted wirelessly without any latency, as the signal is directly passed through before wireless transmission.

4.3. Multi-Receiver Configuration
The system supports connecting one Transmitter (TX) to multiple Receivers (RXs). The maximum supported configurations are:
- 1 TX to 1 RX: Up to 500m (1640ft)
- 1 TX to 2 RXs: Up to 400m (1312ft)
- 1 TX to 3 RXs: Up to 210m (985ft)
- 1 TX to 4 RXs: Up to 190m (820ft)
- Maximum 1 TX to 6 RXs.
4.4. Dynamic Frequency Adjustment
The Elalight Wireless HDMI system features dynamic frequency adjustment, automatically switching to less congested 2.4GHz or 5.8GHz channels. This reduces interference from Wi-Fi, Bluetooth, and other devices, ensuring stable transmission quality without manual frequency selection.

6. Troubleshooting
If you encounter issues with your Elalight Wireless HDMI system, refer to the following troubleshooting tips:
- No Signal/Black Screen:
- Ensure both Transmitter (TX) and Receiver (RX) units are powered on and their indicator lights are active.
- Verify that HDMI cables are securely connected to both the source and display devices.
- Check if the display device is set to the correct HDMI input.
- Confirm that the TX and RX units are successfully paired (refer to Section 3.4).
- Reduce the distance between the TX and RX units and ensure there are no significant obstructions (e.g., thick walls, metal structures) that could interfere with the signal.
- Try connecting the HDMI source directly to the display to confirm the source and display are functioning correctly.
- Intermittent Signal/Flickering:
- Adjust the position of the antennas on both units for better signal reception.
- Minimize interference from other wireless devices (Wi-Fi routers, cordless phones) by repositioning the units or the interfering devices.
- Ensure the power supply is stable and sufficient for both units.
- No Audio:
- Check the audio settings on your source device and display device.
- Ensure the HDMI cables support audio transmission.
- Units Desyncing / Losing Connection:
- This can occur due to signal interference or exceeding the effective transmission range. Try moving the units closer or removing obstacles.
- Perform a re-pairing procedure as described in Section 3.4.
- Ensure both units are receiving stable power.
