I just installed a new (to me) X1 DVR & while going through the install prosses a message appeared showing a bar chart whith 6 bars & only 2 bars light & a message saying my signal is weak & to check for lose cables etc. I had to move a large wall unit out from the wall to get to where the cable comes out of the wall. I checked that the cable was tight & also checked that the spitter (1 goes to the internet modem) connections were aslo tight. By the time I had finished the above & looked at the TV screen the message had gone. I'm not sure if the message left because of my actions or that the message stays only for a short time before going to the next step in the install prosses. Does anyone know how I can check my cable TV signal stregnth? Thanks
