4. Setup Instructions

Follow these steps to set up your Lemorele R15 HDMI Wireless Extender:

1. Attach Antennas: Screw the four provided antennas onto the corresponding ports on both the TX and RX units. Ensure they are securely fastened.
2. Connect Power: Connect the power adapters to the DC 12V ports on both the TX and RX units, then plug them into power outlets. The PWR indicator should light up.
3. Connect Transmitter (TX):
   • Connect one end of an HDMI cable to the HDMI output of your source device (e.g., PC, laptop, set-top box).
   • Connect the other end of the HDMI cable to the HDMI IN port on the TX unit.
   • (Optional) If you wish to mirror the content to a local display, connect another HDMI cable from the HDMI OUT (Loop Out) port on the TX unit to your local display.
   • (Optional) Connect the IR OUT cable to the TX unit and position the IR emitter near the IR sensor of your source device.
   • (Optional) Connect an audio cable to the AUX IN port if needed.
4. Connect Receiver (RX):
   • Connect one end of an HDMI cable to the HDMI OUT port on the RX unit.
   • Connect the other end of the HDMI cable to the HDMI input of your remote display device (e.g., TV, projector).
   • (Optional) Connect the IR IN cable to the RX unit and position the IR receiver in a location where it can receive signals from your remote control.
   • (Optional) Connect an audio cable to the AUX OUT port if needed.
5. Power On: Ensure both the source device and display devices are powered on. The TX and RX units should automatically establish a connection. The LINK indicator will light up when a stable connection is made.

5. Operating Instructions

5.1 Basic Operation

• Plug and Play: The system is designed for ease of use. Once all connections are made and devices are powered on, the video and audio should automatically transmit to the remote display. No software installation or complex configuration is required.
• Dual Band Transmission (5GHz/2.4GHz): The extender utilizes both 5GHz and 2.4GHz frequencies for high-speed and stable transmission, automatically selecting the optimal band.

5.2 Signal Amplification

The built-in signal amplifier ensures stable transmission up to 200 meters (656 feet) without significant delay, even through walls or floors.

5.3 HDMI Loop Out Function

The Transmitter (TX) unit features an HDMI Loop Out port, allowing you to connect a local display. This means content from your source device can be mirrored to two different displays simultaneously: one connected directly to the TX unit and another wirelessly to the RX unit.

5.4 Infrared Remote Control Function

The extender supports infrared (IR) pass-through, allowing you to control your source device from the remote display location. Connect the IR OUT cable to the TX unit and the IR IN cable to the RX unit. Point your source device's remote control at the IR receiver connected to the RX unit, and the signal will be transmitted back to the source device.

5.5 Multiple Receiver Support

One Transmitter (TX) unit can be paired with up to four Receiver (RX) units, allowing you to transmit the same source content to multiple remote displays simultaneously. Additional RX units must be purchased separately.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid or aerosol cleaners.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Avoid dropping or subjecting the device to strong impacts.
• Ventilation: Ensure proper ventilation around the units to prevent overheating. Do not block ventilation openings.

7. Troubleshooting

• No Signal on Display:
  • Check all HDMI cable connections to ensure they are secure.
  • Verify that both TX and RX units are powered on and their PWR indicators are lit.
  • Ensure the LINK indicator on both units is solid, indicating a stable wireless connection. If blinking, try repositioning the units or antennas.
  • Confirm the display is set to the correct HDMI input source.
  • Try connecting the HDMI source directly to the display to rule out issues with the source or display.
• Poor Video/Audio Quality:
  • Reduce the distance between the TX and RX units.
  • Ensure there are no major obstructions (thick walls, metal objects) between the units.
  • Minimize interference from other wireless devices (e.g., Wi-Fi routers, microwaves) by moving them further away.
  • Check if the source device's resolution is supported by the extender and display.
• IR Remote Control Not Working:
  • Ensure the IR OUT cable is correctly connected to the TX unit and the IR emitter is positioned directly in front of the source device's IR sensor.
  • Ensure the IR IN cable is correctly connected to the RX unit and the IR receiver is positioned to receive signals from your remote control.
  • Check the batteries in your remote control.
• Intermittent Connection:
  • Move the TX and RX units closer to each other.
  • Adjust the angle of the antennas for optimal signal reception.
  • Avoid placing the units near large metal objects or other strong electromagnetic interference sources.

9. User Tips

• Optimal Placement: For best performance, place the TX and RX units in a clear line of sight if possible, or with minimal obstructions. Avoid placing them behind large metal objects or near other strong wireless signals.
• Multi-Display Setup: If you need to display content on multiple screens, remember that one TX unit can support up to four RX units. This is useful for presentations or multi-room entertainment.
• IR Control: When using the IR remote control function, ensure the IR emitter on the TX side is directly facing the IR sensor of your source device, and the IR receiver on the RX side is positioned to easily pick up signals from your remote.
• Power Cycle: If you encounter any issues, a simple power cycle (unplugging and replugging the power adapters for both units) can often resolve temporary glitches.
