Yeah it's confusing. I kept fooling with it and found in order for the unit to spit out the EHR you have to set up one of the pre installed ballistic curves to get into the right mode. At the end of the process you can choose what you want to see after the line of sight measurement. I have mine set up so the EHR comes up right after the measurement. I then push the secondary button and it gives me the temp, station pressure and look angle. I even emailed Lecia support asking if there was a simple solution and the answer was not even relevant so I just kept fooling with it.
Hope this helps. I set that thing up months ago and hope I have given you a straight answer. Just play with the darn thing and you will get it long enough to set it up the way you want. I don't use the preloaded ballistic stuff...nothing even close.
