Hi,
I am having a couple of problems with my Pronto. I have somehow managed to stop the backlight from automatically coming on when I press a button onscreen. I went into the menu and followed what the instruction manual says about moving the Level control all the way to the left but it makes no diffrence! The other thing is that the 2nd menu in the setup screen has more options than my manual mentions. For example what is the Light Sensor for? and the Set button? And lastly the Revert menu item is greyed out.

Whats going on here folks???

I am eating humble pie again. Did a search but this time over 2 years and found the answers. The Backlight still seems a bit of a hit and miss. I can now only get it to come on for the same time as the LCD even though it is set to only be on for 5 seconds?

if you have the backlight to be automatic then backlight time=LCD time.


can't remember but there was an issue with an error in the manual try the other direction


it would help if you give more info (Pronto model...)


the original Pronto had a light sensor, it was later dropped because the component used mercury or something and EU law made it illigal so latewr models did not have it. It is exactly as it says, it is the light sensor (how much light it is receiving) later models still had it in the firmware (fake) so that the firmwares are compatible.

The light sensor also made the first Prontos chew throught batteries pretty fast because it was always on sensing the light level.

If I remember correctly, the revert button is normally grayed out the way we use the Prontos.

The first Pronto programming did not use a computer, but you taught everything to the remote itself and that was it. When you started the remote, it had its factory default programming and the Revert button was grayed out. After all, how can you revert when you are already at the factory setting?

As soon as you started teaching commands, the Revert button became active, because then you were not at the factory default any more.

Once we started programming with computers, this got a little less understandable. When you download a ccf into a Pronto, the revert button is grayed out because you haven't made any changes on the remote itself. And why would you want to revert in normal operation? The remote wouldn't go back to your ccf, it would go back to the factory ccf. So it is nice that Revert is grayed out and your kid can't find out what it does.

Sometimes the Pronto messes up and has to revert just to accept a download. If the button is grayed out, what I have done is to teach it a new IR command; then the button is active and it will revert to the factory default.

Someone told me of a method to make it revert to your own ccf when it messes up, but I haven't been successful with this. Someone made a comment that while you can do that, your ccf has to be pretty darn small to do it.
