screen remains active. It is important to note that this switch does not disconnect power 
from  the  monitor.  Power  is  always  supplied  to  the  internal  AC/DC  power  supply  (or  the 
optional 24V DC to DC converter) which in turn, continually supplies power to the internal 
monitor electronics and the optional touch screen controller.
