hrr115P38Lightning instruction manual is massive (digitally, 36.7MB) and I had to put the entire .pdf file in dropbox.com - - You can download a complete copy by clicking on the link below:

https://www.dropbox.com/s/dgfq9i3eyssx0if/hrr115%20P-38%20Lightning%20-%20Complete.pdf?dl=0

Once there, on the upper right side of the page should be 3 dots.  Click on the dots and choose "download".  Should you have any problems at all, e-mail me and I can send the link directly.
