I am having the same problem that David Glass has or had but have not found a answer. John Sherman - Here is his question
New FIOS Quantum Box. Remote used on the old FIOS box does not work. Major issue - cannot remove the screen saver that says ":Press Menu Button to Continue". Menu button on old remote does not work. Need a remote for Arris IPC 1100, please!
I assume you have already done a proper Forum Search for your model number in case other people have already answered your question ?
If so and that didn't help then check out this thread: https://community.sling.com/message/10363#10363
Come back if it that doesn't help either.
