DNA Engine & DNA Engine Tetrad Operations Manual

Turning the DNA Engine On

Move the power switch to “1” (the “On” position). In most The fan will
turn  on,  and  the  power  light  on  the  keyboard  will  glow  red.    In  most
cases a self-test of the heat pumps will begin running (see note below).
Its progress is tracked on a screen in the LCD window:

This screen disappears in 1 minute. If a problem is detected, the display
shows an error message.

Note:

If the Alpha unit’s block or heat sink is not at ambient tempera-

ture (typically because the Alpha unit was recently in use), the machine
will skip the self-test.

If the self-test does not detect any problems, the Main Menu is displayed:

The DNA Engine is now ready to execute programs.

Understanding the Main Menu

The  Main  Menu  is  the  common  access  point  to  all  programming  and
machine configuration screens:
