Scrolling Ball Indicator
The first time ac power is connected to the system, or whenever ac power is disconnected
from the system and then reconnected, a scrolling ball that moves from left to right may be
visible in the operator panel display before the first 8xxx progress code appears. It may not
remain in the display long enough to be visible. If seen, it might remain in the operator panel
display for a time of less than one second, or up to 3–5 seconds, depending on the system
and configuration.
