● Is the lamp of the twisted pair distributor lit-up?
Is the power adapter cable properly connected toAC100-240V line or a twisted pair distributor?
● Is there a source that causes noise near the cables?
A noise filter should be used in case of noise.
● Is the CAT5e cable properly connected to the Input andOutput of the distributor? Is cables damaged?
● Is the CAT5e cable properly connected to the RJ-45 ?
If the twisted pair cable is carrying weight, please use thecable mounting kit.
● Is the receiver working properly?
Adjust the LEVEL /PEAKING of the twisted pair receiverreferring to the instruction manual of the receiver.
● Is the lamp of the twisted pair transmitter lit-up?

The image of PDP isflickering or thereis noise● Is the twisted pair cable near the AC line? It should
be far from the line.
● Is there a source causing noise close to AC
adapter of the twisted pair distributor? A noise filter should
be used in case of noise.
● Is the CAT5e cable properly connected to RJ-45 connector ?
If the twisted pair cable is carrying weight, please use the cable mounting kit.

● Is the length of the cable within the recommended transmission range ?
Please note that use beyond the recommended distance will require outside
support.
Other situation● Is the CAT5e cable properly connected to RJ-45 connector?
If the twisted pair cables is carrying weight, please use the cable mounting
kit.
● Is the receiver working properly? Adjust the LEVEL/PEAKING of the twisted pairreceiver referring to the instruction manual of the receiver.
