Jose, use the center button to go into the menu, then scroll to “Advanced Shortcut.” Open that up and you will see the items that you can disable. Scroll left and you will see Ballistic Calculator, WiFi, Recoil Activated Video and such. Once you have each of those highlighted you can press the center button to put a diagnal line over the icon which will disable it.
cmatura, do you currently have the RT model? I have an XT 6.5x that required a 20 MOA picatinny rail to keep the crosshairs relatively centered on a bolt rifle. Isee you no longer have the 4k. Did you not like it? If you don’t mind, tell more about the RT.
