3. Pairing (for multiple RX units)
The system supports connecting one Transmitter (TX) to up to four Receivers (RX). When adding multiple RX units, they must be paired with the TX. Refer to the specific pairing instructions in your product packaging if not automatically paired.

Figure 7: The system supports up to 1 TX to 4 RX connections. Note that transmission distance may decrease with more receivers.
Operating Instructions
Wireless Transmission
Once powered on and connected, the TX and RX units will automatically establish a wireless connection. The system utilizes 5.8GHz frequency for high-speed transmission and dual antennas for enhanced signal stability, allowing for transmission through obstacles like walls or glass.

Figure 8: The system offers up to 820ft transmission range with 0.01s low latency.
IR Remote Control
The system includes IR cables to allow you to control your HDMI source device (e.g., DVD player, set-top box) from the location of your display (where the RX unit is). Connect the IR Blaster cable to the TX unit and position its emitter near the IR receiver of your source device. Connect the IR Receiver cable to the RX unit and position its receiver to face your remote control.
