Edited for correct path/file name: Answered my own question. You can modify the [install drive]:\spectrum\tomcat\webapps\spectrum\console\gis-view.jsp file. Save a backup. Then, edit it and search for "startmap". In the function Startmapping is this line: "var marker_title=..." I modified it to: "var marker_title="Device : " +model_name+"\n" + "Location : " +location;" It works perfectly!
