There are 4 pages in the Default Tools Menu. My PCF only shows the 1st page. I must have done something many, many downloads ago. Is there something I can do to get the language, firm keys, and free memory pages back? Would a merge with default Philips PCF do the trick?

I don't think there is anything in the PCF for this. Are you sure they are missing? How are you trying to get to these pages from the first page?

For the TSU3000, remember that they changed the Tools/Setup structure changed when they changed the interface to match the TSU7000.

For the TSU7000... maybe write protected? Or you're calling Tools instead of Setup?

Well, here is what I am comparing it to:
In default 7000 PCF when you click on the pronto icon...you find yourself at the "settings" page, and choosing "settings button" you go to the setting page. There is a button at the top right of the page showing "1 of 4" on the button. When you click on that button you go to a page with 4 settings buttons....which in turn takes you to each of the pages.

On my PCF when you click on the "1 of 4" button it takes me to page "1", with no other buttons or choices...except to click on Pronto icon and exit.

My PCF is working perfectly...I am just unable to change any settings associated with these pages or see my free memory.

I bet you deleted all items on the Page Overview page of your System device. Put em back and I think it will work as expected. It is undocumented but the Page Overview page of Settings uses the images/buttons in the Page Overview page of your System device in your PCF.

Thanks for the tip. I'm all fixed up.
