3.2.3 Shutting Down
Turn off power using the power ON/OFF switch.
Warning: DO NOT UNPLUG THE M300! The blackbody has a temperature
controlled cooling fan that remains active until the enclosure temperature is
below about 140°F. If the power is interrupted by external means, this cooling will
not occur and the devices in the enclosure may overheat. If power fails during high
temperature use, remove the top, rear cover plate to allow better convection cooling
until the blackbody is cool.
