3. Scroll through the event list with the UP and DOWN keys.
4. Exit the event list by pushing the LEFT key.
It is possible to set the order in which the events are sorted. If the
"Order" -parameter is set to "New-Old", then the first event in
the EVENT LIST is the most recent event.

Forced Control (Force)

In some menus it is possible to switch a signal on and off by using
a force function. This feature can be used, for instance, for testing
a certain function. The force function can be activated as follows:
1. Move to the setting state of the desired function, for example DO
(see section "Configuration and Parameter Setting").
2. Select the Force function (the background color of the force text
is black).
