EMERGENCY SHUTDOWN

The large red mushroom
switch located on the top
of the LR-20 is the Emer-

which is also the main on/off
switch for the unit. To turn
the power on, the user must
rotate the switch 90 degrees
in the direction of the arrows

down until it latches will
immediately turn the unit off.
