By default, published calendars have small icons at the bottom for links to an RSS feed and iCalendar (ics) feed of your events. If you don't want these icons shown, you can add this parameter to the url you are using for your calendar:
rss_link=N
If it's the first parameter you are adding, it must be preceded with a question mark (?). If it's the second (or greater) parameter you are adding, it must start with an ampersand (&). Here are two examples:
