Purpose
The purpose of these exercises is to lead you through most of the menus, buttons and functions needed for operating the system in a safe way
The exercises are written for general operation and you might therefore find exercises not relevant for your use of the system
Note that some functions are not available in the simulator, but the menus will be present to show you how to do the operations
