Stop Projection - Digitalis Digitarium Alpha User Manual

4) If you want to make sure you are in the center of the dome, press
up an azimuthal grid. Move the projector as needed to center the grid on the
dome, and then turn off the grid.
5) Don't forget to change your latitude, longitude, and time zone, if necessary.
See the section entitled " Menu Mode" for instructions on changing these
settings. If you modify settings and want those modifications to become your
default settings, you will need to save them as default, using the menu.

Stop Projection

To stop projecting onto the dome, aim the DLP projector remote control into the
vents near the lens. Press and hold the power button until a dialog pops up,
asking whether you really want to stop projecting. If you do, hold down the power
button again. Otherwise, do nothing.
It takes 90 seconds to shut off and cool down the projector lamp safely.
During these 90 seconds do not shut off power to the projector or you
could damage the lamp. You will not be able to resume projection until after this
cooling period is completed. While cooling, the indicator light will flash orange.
Once finished, it will be steady orange.
Note that the computer components of the Digitarium Alpha are still running.
To resume projection, turn on the projection lamp just as you did the first time.
If you will not be restarting projection soon, place the lens cap over the lens to
protect it.
