Thank you for the excellent thread, espeacially the complete follow up.
I too have recently acquried an RM-X4S and had a follow up question.
It seems to work, however the response to button presses is intermittant. Half of my button presses result in no response. I am wondering what repsonse people are getting? I understand that there is an intentional response "release delay" behavior. I have yet to resistance test the stalk and/or view the Hijack button codes. I really do hope to hear that something is awry with my stalk/tuner, because its almost un-usable this way.

Also, I see how to get into the menu but once in it seems Skip should allow you to scroll the menu. Without that all I can do is down-down-down...pretty limiting. What am I missing besides doing my own ir-mapping...or could it be a faulty stalk/tuner?

Regards,
Michael
