+    If a <I>suspend</I> is scheduled, all further observations are discarded. The
+    <I>suspend</I> itself is just a <I>sleep</I>. If very soon, a new observation
+    will be started, it is best to schedule the <I>suspend</I> before it, otherwise
+    the observation might get started before the <I>suspend</I> is executed. Note
+    that a suspend does <b>not</b> interrupt the current observation, but will work
+    as a normal entry, i.e. the previous measurement (usually a <i>data</i> run) will
+    be finished before the suspend is executed.

+    If a <I>resume</I> is scheduled, it has the same effect as if the preceeding
+    <i>suspend</i> was removed. That effectively means that the last observation
+    which was scheduled before the <i>resume</i> will be executed as it if just became
+    valid. Consequently, if it is scheduled close to the change of observation, 
+    it makes sense to schedule it after this observation, to avoid that the previous
+    observation becomes effective.
