TERRA Operative:
Here's the cleaned up version of the manual.
I uploaded it to the HP-Agilent-Keysight Groups.io as it's just a little to big to upload here. (I didn't want to crunch it down too much).

That looks awesome! What's your process like for cleaning up pdf's? I have a horrible scan of a manual that I've been trying to clean up with acrobat pro and scantailor, but haven't had much luck. Unfortunately, I can't find any better scans online due to the age of this device
TERRA Operative:
I use Photoshop and Acrobat.
Usually I separate the pages into two folders, one for left pages, one for right pages (The text is often offset away from the spine of the book to allow space for the holes for the folder).
Then I set up a script for each side in Photoshop that adjusts the Levels to crush the text to black 'just enough' and the same with the whites to remove the paper texture etc. Also in the script I set up marquees to delete any visible page edges and hole punches etc (This is where I find the separate left and right scripts are needed). Then finally I crunch the colour space to 'Indexed Color' with 16 shades of grey (you can go to monochrome bitmap like many other manuals around the net are for smaller file sizes, but we aren't hurting for storage space these days and 16 colour grayscale looks much nicer). If there are colour pages, I'll adjust the colour space for just those pages as needed.
Then I run the script on the pages, saving as png.
After inspecting the pages for problems or errors etc and correcting as needed also a quick overview for any left-over blemishes (like from a smudge or dirt on the scanner), I drop them into Acrobat and set up the bookmarks and page numbers etc. Also, I delete the blank white images from any blank pages to save some more file size.
Then I kick out an optimised pdf (with the image settings turned off because we already took care of it in Photoshop) to strip out any extra unneeded junk and it's done.
Some manuals need schematics stitched together and bad scans repaired etc so it can get manual and tedious sometimes, but good colour scans in 600dpi make a world of difference (your scans were actually pretty nice!)
The colour scan makes a difference as the paper texture is often yellowish so is easier to remove than grayscale against the black text in the case of a grayscale scan.
