In order to use the digital coordinate sheet file efficiently, you first need to know how to use the "find" function on your specific device.

For iPhones

Open the file below in Safari (Chrome will not work).  Then, in the search bar at the top of the browser enter your label (i.e., R3).  DO NOT TAP ENTER.  Scroll down, or look at the bottom of the drop down menu and you will see results that say "In This Document."  Tap "Find (your search term)" and it will take you to your specific coordinate sheet, based on your label.  Once you find your coordinate sheet, TAKE A SCREENSHOT!

Alternatively, if you use a PDF viewer to view your PDFs, then there should be a button at the top of your screen that has a magnifying glass.  Tap this button then enter your label.  It should take you to your coordinate sheet.  Once you get there, TAKE A SCREENSHOT!

For Androids

In order to view pdf documents on Android, you must have a pdf reader.  Within your pdf reader at the top there should be a button that looks like a page with a magnifying glass.  Tap that button and you can then enter the label you want to find within the document.  Once you find your coordinate sheet, TAKE A SCREENSHOT!
