5 Solutions to Common Problems

In most cases, nearly every issue with the Cobra series can be resolved by checking the CAT 5 termination and making sure that it’s pinned to the TIA/EIA 568B wiring specification. However, there may be other problems that cause the system to not perform as it is designed. Below are solutions to the most common installation errors.

Problem:	No video signal at the transmitter local port or at the receiver.
Solution:	Check that both units are powered.
	Ensure EQ adjustment is set correctly — turn knob slowly. • Make
	sure the CAT 5 cable is terminated correctly per the TIA/EIA
	568B wiring specification.
	Is the display device powered on and functioning?
	Check to ensure display settings (resolution, refresh rate, etc) are
	compatible with input signal.
Problem:	Poor video quality.
Solution:	Have all receiver adjustments been finished?
	Ensure EQ adjustment switches are set correctly

Solution:	Powered speakers are required. Make sure speaker power is ON
	Check input source levels from the source device. Make sure the
