Before You Start
For best performance:

Step-by-Step Setup Guide
Step 1: Connect the Transmitter (TX)
- Connect your source device (PC, Blu-ray player, streaming box) to the HDMI IN port on the transmitter

- Plug in the power adapter
Once powered, the indicator light will turn on
Step 2: Connect the Receiver (RX)
- Connect the HDMI OUT on the receiver to your TV or projector
- Plug in the power adapter
The receiver will automatically power on and begin initializing
Step 3: Pair the Transmitter and Receiver
Before use, the TX and RX must be paired:
- Connect TX and RX temporarily using an HDMI cable
- Wait for the pairing indicator to stop flashing
- Disconnect the HDMI cable once pairing is complete
If needed, you can reset pairing by holding the reset button for 6+ seconds
