HI DOES ANYONE HAVE TECHNICAL DATA ON BROOKS/ ACORN 180 (2016) CURVE GOING LIFT PLEASE. MY PROBLEM IS IT HAS BEEN LEFT DISCHARGED FOR SOME TIME AND APPEARS TO HAVE LOST SOME OF THE PROGRAMMING DATA. IT IS SOMETIMES BUT NOT ALWAYS GOING INTO ERROR IN BOTH DIRECTIONS WHEN CHANGING TRACK ANGLE AND SOMETIMES FORGETTING ITS PROGRAMMED LIMITS. IT HAS BEEN INSTALLED IN EXACTLY THE SAME ORIENTATION AS ORIGINALLY INSTALLED. I AM A RETIRED ELECTRICAL ENGINEER FROM AN INDUSTRIAL AUTOMATION BACKGROUND AND HAVE INSTALLED THIS FOR A FRIEND FOR FREE AS HE IS IN NEED AND HAS LITTLE FUNDS. I CHOSE IT FROM EBAY AND REMOVED IT MYSELF. ANY INFO WOULD BE VERY MUCH APPRECIATED. REGARDS JOHN ferrarijohn348@hotmail.com
