OutputOn/Off: Pushbuttonwithdualindicatorlamps.
Note: all voltage and current levels set via the keyboard are displayed on
a separate 0.3" 4 digit display. This entry preview system ensures that
the user can observe the value entered before it is effected thus avoiding
possible error. The display is also used for setting additional functions
and for displaying watts.
