connection, simply check the desired box(es). To break a connection, uncheck the desired box(es). Note that
two types of connections are shown: Manual connections and dynamic connections. Manual connections result
from configuration settings or functions. Dynamic connections result from Beltpac operations or the front panel
Talk button. Checking a box in the window always results in a manual connection. Manual connections are not
overridden by dynamic operations. However, clearing a connection manually does not prevent a later dynamic
or manual connection from being established. Note that the Audio Connection Matrix window can only be
opened while PC850 is “online”.
