Should the ICATS and projector be turned off after each session?

As a rule, the projector should be turned off after each session as the projector bulbs have a "lifetime" and wear out over time. The ICATS takes minimal power and can remain on with no harmful effects. If you want to turn off the ICATS, make sure to shut it down properly with "Right-click / Quit / Shutdown", followed by removing power (switch, or unplug). Removing power from a running ICATS is not recommended as it could cause the SD Card to fail, though typically no harm occurs.
