The flow display computer receives site-specific operating instructions
from Active Memory.

a Security code.
Arrow Keys Use the <Up, Down, Left and Right> Arrows to navigate through the
Installation Menu in their respective directions. The <Up or Down>
Arrows allow you also to scroll through option list items.

computer acquires its receive signal and enhances other parameters
for optimal operation at a site.
