Hi beardofthedead, welcome to the forum!
Cut & pasted below is a likely explanation saying Pressure Gain may be a fine calibration feature. Newer machines would not need this because they are more accurate.
I suggest that if you were to look up your altitude (using googleEarth or weather.com or a map or whatever) and were to set the altitude accordingly, that would probably be a good thing, but not to worry about the "pressure gain" setting.
(Or, if you want to go to the trouble, maybe the (!*#&^@) DME who sold you this dinosaur would be willing to check it for you.)
Re: inquiry on resmed s7 pressure gain setting

This is just a guess on my part...
I'm guessing the "pressure gain" setting has to do with adjusting the pressure delivery, if you checked the pressure with a manometer, found it to be a bit "off" and not actually delivering the amount of pressure the machine said it was delivering. But, I may be wrong about that since you say you've not been able to change that particular setting.
Anyway, this was in an old (2003) issue of rt magazine:
CPAP Flow Generator
ResMed Corp, San Diego, has added the S7™ Lightweight to its family of flow generators for the treatment of obstructive sleep apnea. A fixed CPAP flow generator, it features ResMed’s modular humidification system and gross-altitude and fine-gain adjustment for accurate pressure delivery
The part I emphasized in bold red is what makes me think the adjustment you described is ... what I think it is.
Perhaps you could take the machine to a kindly DME who would take the few moments needed to give the machine a quick check with a manometer. If I couldn't find a DME willing to do that for free, I'd not worry about it.
