I need the setup/ mode program code summary for an Wild Heerbrugg T2000 theodolite, also how can I adjust the focus of the recticle/ cross hairs on the main telescope as the eyepiece has no provision to focus recticle and the focus is about 2 milimeters ( .079 in. ) out of focus as determined by moving eye piece away from telescope body, ie. recticle is to close to eyepiece. Any help or information will be appreciated. Regards, Jerry
