A:AnswerHI RIchele,
I'm not sure if this remote will work with an Entone cable box. Can you call our helpline at 1-800-420-7968?
thank you for your inquiry and have a great day
A:AnswerYes, but it turned the box off to the point that it had to do a reboot of some sort each time we turned it on which added to the time for a picture to appear.
A:AnswerIm not sure if it is compatible but I'd bet a glass of water in the desert that it'd work.
If it doesn't keep your receipt. Best Buy has a flawless return policy. Good luck.
