Paul's right - there's no "save changes" or even "register signal" like you have in NEC's.
When the PJ senses a new horz/vert refresh rate that hasn't been used before, you'll see "NEW SIGNAL" in the bottom right corner for a few sections. The signal is registered at that point - you don't have to do it yourself. Any changes you make at that point as saved as well. You can't go through a bunch of changes and then back out of them. Everything is saved at every click of a button.
The buttons on the remote let you select the INPUT you want to use. The '5' button is the RGBHV input(If I remember correctly 1 and 2 are composite and S-video I think). If that's the ONLY input you use then you should only have to press '5' once and never again as the PJ should always return to the last input you used every time you power it on. I have noticed however that my Barco needs to have input 5 reselected after a power outage or when it's been unplugged.
But putting a "9" in front of any input number (ex: '95') you get a second set of settings that you can use for that same horiz/vert refresh rate. Like Paul said, it's really only useful for people with scalers that don't do anamorth. squeeze so you have to do it in the PJ. So it's useless for anyone with a modern scaler or an HTPC. I've never used it myself...
So when you get a new Barco, the usual sequence would be as follows:
- Go into the menu and erase all memories completely.
- Feed the PJ the HIGHEST signal you expect to use (usually via RGBHV which is input 5). (Lower resolutions use the settings from higher ones to extrapolate geometry settings so it's always good to set up the highest resolution first).
- Hit '5' on the remote.
- The PJ senses the new signal and creates a slot in memory for it (out of the 32 available).
- Do the complete mech/elec setup. All changes are saved as you go along. Write down these numbers in case you plan on being adventurous one day.
- That's it. Nothing else needed. As you turn off the PJ (go to standby) and turn it back on it should return to the same input (5 in this case) no matter what you're feeding the PJ (it doesn't autosense and switch by itself).
Having to hit '5' every time leads me to believe that you're powering the PJ down COMPLETELY. Most people just go to standy where everything's off except for the CPU module that is feed 9V DC from the LVPS, so that it can come back on by pressing on/off via remote. (Leave the push on/off button on the PJ in the 'on' position). I think there's a dip switch in the row of little switches on the big black cpu module that lets you go into standby when you hit power off on the remote. I only *completely* turn of the power when I go on vacation.
Funny- I had the opposite problem as you when recently working on an XG75 that I had for a short period: I would always forget to save my changes and couldn't figure out at first why the PJ wasn't auto-registering new signals!!
