I have added the 17 degree Magnetic Declination into the map that The Zodiac requested which is something someone with a compass would do for hiking or in a military situation.

"The Mt. Diablo code concerns Radians & # inches along the radians."   

Zodiac is working in Imperial calculations which may mean the old Degrees, Minutes and Seconds

The buttons maybe military and datum's.  Maybe he was a military surveyor or similar that worked for Denning?
