3. Setup Instructions

The Lemorele Wireless HDMI system is designed for simple plug-and-play operation. Follow these steps to set up your devices:

1. Identify Units: The units are labeled 'TX' for Transmitter and 'RX' for Receiver.
2. Connect Transmitter (TX): Plug the TX unit into the HDMI output port of your source device (e.g., PC, laptop, camera, set-top box, PS5, Nintendo Switch).
3. Connect Receiver (RX): Plug the RX unit into the HDMI input port of your display device (e.g., TV, monitor, projector, advertising display).
4. Power On: Connect the provided USB power cables to both the TX and RX units, and then plug the other end of the USB cables into a power source (e.g., USB port on your device, USB wall adapter). Ensure both units receive stable power.
5. Automatic Connection: The TX and RX units will automatically pair and establish a connection. The display device should show the mirrored or extended screen from your source device.

4. Operating Instructions

4.1 Basic Operation

Once the TX and RX units are connected and powered, they will automatically establish a wireless connection. Your source device's display will be mirrored or extended to the connected display device.

4.2 Display Modes (Projection vs. Extension)

The system supports two primary display modes:

• Projection Mode (Mirror Mode): The content on your source device's screen is duplicated on the larger display. This is ideal for presentations or sharing content directly.
• Extension Mode: The larger display acts as an extension of your source device's screen, allowing you to have more desktop space or display different content on each screen.

The specific method to switch between these modes depends on your source device's operating system (e.g., Windows display settings, macOS display preferences).

4.3 Multi-Transmitter Pairing

The system allows up to 8 TX units to be paired with a single RX unit. This is useful for environments where multiple users need to share a single display, such as conference rooms or classrooms.

4.4 Mobile Phone Screen Projection

The device supports Apple/Android mobile phones for screen mirroring or projection. In projection (push) mode, you can exit the playback interface on your phone for other operations, and even turn off your phone screen without affecting the large screen's playback. This mode does not consume mobile data or phone power.

4.5 WiFi Networking Setup

The device supports 5G/2.4G dual-band WiFi. You can set up WiFi networking through a dedicated button, making it simpler to operate compared to other screen-sharing devices.

6. Troubleshooting

If you encounter issues with your Lemorele Wireless HDMI system, please refer to the following common solutions:

• No Signal on Display:
  1. Ensure both the TX and RX units are properly connected to their respective HDMI ports and are receiving power. Check the power indicator lights on both units.
  2. Verify that the display device is set to the correct HDMI input source.
  3. Try connecting the TX unit directly to the source device's HDMI port, or use the provided HDMI extension cable if space is limited.
  4. Ensure the distance between the TX and RX units is within the specified 50m range and there are no significant obstructions (e.g., thick walls) that could interfere with the wireless signal.
• Poor Video/Audio Quality:
  1. Check for potential sources of interference (e.g., other wireless devices, microwaves) and try to minimize them.
  2. Ensure the TX and RX units are within optimal range and line of sight if possible.
  3. Verify that your source device is outputting a stable 1080P@60Hz signal.
• Connection Drops Frequently:
  1. Ensure both units are receiving adequate power.
  2. Check for strong wireless interference in the environment.
  3. Try repositioning the units to improve signal strength.
• Device Not Responding:
  1. Disconnect and reconnect power to both TX and RX units to perform a soft reset.
  2. If issues persist, check the manufacturer's website for the latest firmware updates and instructions on how to perform an online upgrade.

7. User Tips

Based on common user inquiries and feedback, here are some tips for optimal use:

• Model Differences: While there are variants like G57, P20, and Q50, their core functionality (1080P@60Hz wireless transmission) remains consistent. Any specific feature differences would be detailed in their individual product descriptions.
• Gaming Console Compatibility: The system is compatible with various gaming consoles, including PS5 and Nintendo Switch, allowing you to wirelessly project your gameplay to a larger screen.
• Signal Through Walls: Wireless signals can be attenuated by physical obstructions like walls. For best performance and to achieve the maximum transmission range, maintain a clear line of sight between the transmitter and receiver whenever possible. Thick walls or multiple obstructions will reduce the effective range.
• Power Source: Always ensure both the TX and RX units are connected to a stable power source using the provided USB cables. Insufficient power can lead to unstable connections or poor performance.
