    # Datums und Zeitformate, ggf. anpassen. 
    view.dateFormat = %d %B
    view.timeFormat = %H:%M
    # Erinnerung Termin
    event.remind = 0
    # Anpassung Templates
    view.list.listTemplate = fileadmin/templates/CAL/list.tmpl
     view.event.eventModelTemplate = fileadmin/templates/CAL/event_model.tmpl
}

and my changes in event_model
all other is standard
example of one entry TEMPLATE_PHPICALENDAR_EVENT_LIST....

<!-- ###TEMPLATE_PHPICALENDAR_EVENT_LIST_ODD### start -->
	<dt class="vevent">
		<div class="dtstart-container"><abbr title="###MICROFORMAT_START###" class="dtstart">###STARTDATE### ###STARTTIME### ###ENDTIME### ###CATEGORY### ###LOCATION###</abbr></div>
		<div class="summary"><!-- ###EVENT_LINK### start-->###TITLE###<!-- ###EVENT_LINK### end--></div>
	</dt>
<!-- ###TEMPLATE_PHPICALENDAR_EVENT_LIST_ODD### end -->

if the MARKER ###LOCATION### is not inside then all others additionals will be shown 
like CATEGORY and ENDTIME 

if the MARKER is inside the page is only empty
with following html code

<html>
<head></head>
<body></body>
