Use this potentiometer to adjust the video signal gain to achieve the desired image brightness Too little gain may cause the image to look dark or dull while too much gain will cause the image to look washed out 6 Troubleshooting Warnings Do not use to link between buildings unless potential grounding and shock hazards have been addressed The video distribution system is intended for dry indoor non hazardous locations Do not use the RJ45 connectors to connect to any other type of equipment as this may damage the video distribution hub extender or remote interface module The units may not work properly in the presence of large GROUND potential differences Problem The power LED does not illuminate or illuminates very dim Possible Solution Check that the 6 VAC power supply is connected to the unit and connected to an AC power outlet of the correct voltage Problem Computer will not adjust to the desired video display settings Possible Solution The computer may be failing to communicate with the local monitor Try connecting the local monitor to video output 1 on the video distribution hub located near the video input connector If there is no local monitor in the system you may need to connect one temporarily to adjust the video display settings Note the remote monitors should be capable of operating with the same video display settings as the local monitor Some LCD monitors will operate with a variety of
