3.3  Shut-Down 
Prior to working with the MR system, familiarize personnel with the function and location of 
the installed ON/OFF switch. 
 
The ON/OFF switch has the function to switch on/off the electrical power of all electronic 
devices  of  the  scanner,  except  the  internal  line  power  distributor  and  the  computer 
console. The switch does never affect the magnet, which is always on. 
 
The ON/OFF switch is installed near the magnet. It is recommended to check in regular 
intervals the free access to the unit. 
 
If a risk of electrical hazard occurs, the main power supply of the system must be switched 
off immediately using the ON/OFF switch.
