Trouble Shooting
1. How to deal with video ash or cut o during the installation?
• Power indicator should be solid on and status indicator should be
blinking. If not, please check if the power adapter is well connected.
• Link indicator should be solid on. If it is blinking or off, it is likely a
problem with your Ethernet cable. Please change to a qualified cable
(Cat5e/6/7, EIA/TIA 568B) and ensure the cable length is within the
maximum distance (230ft for 1080P, 131ft for 4K).
• HDCP indicator should be solid on or blinking. If it is off, it means no
signal pass through. Please check if the HDMI cables are well connected
to the source and TV, and the Ethernet cable that connects transmitter to
receiver is normal. Try a better HDMI cable or Ethernet cable.
2. How to deal with a weak or not working IR signal?
• Make sure the IR cables are correctly installed according to the
Installation Instruction diagram above.
• Check if the IR emitter head is secured over the center of the device IR
receiver window. The best position may vary depending on the device.
Please refer to the device user manual. If the signal is weak, please try to
adjust the position.
• Pay attention to the control angle and distance as below.The control
signal will be better when your controller is pointed at the IR receiver
head directly.
Enabled Angle 0° 30°(Horizontal) 15°(Vertical)
Distance 26ft (Max) 15ft (Max) 10ft (Max)
