I'm going to do some investigative work with my 1000. I've been focusing on the 900 and a couple of other URC remotes as of late.

They do have similar button action. Too soft in my opinion.

btw, here's something to try... with one of the keys you
see the problem with, try programming a macro. Send some
key first that'll be ignored. Then send the real key.

Maybe the remote is having issues waking up and sending
the first key ...

I have had the same problem with buttons programmed with macros; none of the commands are sent. Press the button a second time and everything works perfectly.

Has anyone had any issues with the light button? Once or twice I have pressed the light button and got no response. The first time I thought I must not have pressed hard enough. When it happened the second time I swear I pressed hard enough. This has only happened twice whereas other buttons have been affected with greater frequency.

That sure sounds like the remote is just missing the keys as opposed to messing up the processing of it.

Does it always miss the first key pressed after the remote was left alone?

Or can you be say punching in a channel, and it misses a digit out of the middle?

(goal: isolate a startup problem)

Does it always miss keys you use all the time, or does it seem like it'll miss any key?

(goal: isolate a bad contact)

In my case it is totally random and is not isolated to once specific button. As others have stated the button works fine on the second press.

So for instance, if you wanted to press the GUIDE button on your remote, but you always pressed the EXIT button first... do you think it would ever not bring up the guide?

What I'm guessing here, and just trying to isolate, is that the remote probably drops in to a low power mode between keys strokes. When it wakes up out of that low power mode it might be doing it too slowly at times to detect the button that was pushed.

If this is the case then, then I imagine longer pushes would tend to be detected anyway, and anything you could do that'd keep the remote awake and in a higher power state would tend to eliminate the problem. So for instance when the backlight is on, the remote is minimally thinking about when it needs to turn the backlight off. This is all conjecture and guess work without any knowledge of how the remote's software actually works, but it's seeming plausable.

Try holding the buttons down longer and see if it ever misses ...

Oh, and if I'm right this may very well be an issue that can be fixed in the firmware. The firmware may need to be rewritten to check the keypad more quickly and any debouncing done in s/w may be to be reduced.

Sunstar,

Yes, I have also had problems with the light button not responding on the first press.

I have held the buttons down when they don't respond and it has no effect until released and pressed again.

There would definitely be instances when guide would not come up.

Holding the buttons down longer does not help; exactly as mentioned by Chuck above.

I've also had numerous instances where the back light doesn't turn on the first time I push the button. It always turns on with the second press.

Like everyone else has state, holding the buttons down for a longer period of time has no effect on making the button work on the first press.

If the TX-1000 uses the same OS and similar firmware it would stand to reason that it to would have the same problems as the 900.

The 900 and 1000 use the same OS. The 3000 and the 950 use a version of Windows CE, which is different than the first two remotes.

Well, if it's a firmware problem it's a weird one.

I'm sure the engineers are in total agreement with you, Jon!

Hopefully they're working on it, but problems that don't reproduce easily are a pain to solve. Stop selling the remotes and I bet it becomes a higher priority!

Its real easy to reproduce. Press Info over and over until it happens, usually within 20 tries.

Easily reproduced on YOUR remote WP. More intermittent and strange on other remotes. Plus, a little different on each person's remote, except perhaps for the firing of the IR on the second button press every time.
