What should I do if there is no image or audio on the display?

Check that the display is on and set to the correct HDMI input. Verify the LINK LED on the receiver is solid (flashing indicates no signal). Ensure the transmitter's power LED is blue (red means no input signal). Also confirm the source resolution is supported.

How do I stabilize an unstable image?

Press the LENGTH or RESET button on the transmitter to re-identify the signal. Alternatively, disconnect and reconnect the CAT cable.

Can I control the source device remotely?

Yes, the set includes an IR blaster (connect to transmitter) and two IR receivers (connect to receivers) for IR passback up to 60 kHz. This allows you to remotely control the source device from the display locations.

What type of network cable is required?

Use shielded or unshielded CAT6/6a/7 cable terminated to the IEEE-568B standard. The maximum length is 40 meters.
