Frank,
I'm sorry to hear this! Try re-positioning the Extender. Make sure that it's directly in front of the remote sensor on the cable box, and see if that clears up the issue for you. You always want to make sure that it's no farther that 2 inches in front of the remote sensor. With some of the cable boxes, the extender is very sensitive, and it has to be in the perfect spot.

I'm trying to use the extender cable to control my Charter Comm. Set Top Box (Model #DC550DR) but I can't get it to work. I've had the STB for about a year and can't find its Model # when running the Remote Set Up.
I only need STB control for changing channels and, strangely, it sometimes works but rarely.
Any ideas for me, please?
Frank
