RST
– The RST position is used to reset the system. To place the
system into the RST position requires that the push button on the back of
the switch be depressed and the switch turned to the RST position. This
essentially removes all electrical power from the system.

- In the OFF position, electrical power is available to the system
CPU for maintenance use only.
Standby

active and start the cool-down process for the IR camera. In this position
the HCU switches and controls are ineffective except the Power Switch
and Backlight Control.
ON
– In the ON position the system becomes fully operational.
