Demonstration Modes
Volts
The demonstration modes are provided primarily
for sales personnel.

of the +5, -5, +12 and -12 V power supplies and is
provided as a diagnostic tool. The voltages should
be within ±5% of the nominal level.

Mode not enabled
Unstdy Marker Four markers are superimposed
on the input picture. After processing through
Archangel One, the amount of movement of the
markers is indicative of the amount of correction
Archangel One is performing. This is especially
useful for demonstrating the effectiveness of
Archangel One with a single monitor.
Temp
Unstdy Graph
When the temperature limit is approached, an
intermittent chirp will be heard from the box. A
continuous beep will be heard when the maximum
range is exceeded. The unit will continue to run
and will not automatically shut down if the
maximum temperature is reached, however it is
advised that the unit should be turned off at the
first opportunity.
The measured horizontal and
vertical motion is displayed on a
graph, with history detailing the
last 250 fields. A vertical line on
the graph indicates a detected
cut.
Note that Archangel One will not correct
unsteadiness when the graphs are displayed.
Graph H-Gain
The horizontal gain of the graph may be adjusted
using this control.
If the unit is overheating, check that the ventilation
fan is operating on the rear of the unit and the
airflow is not restricted by external objects or the
build-up of dust/dirt in the fan grille.
Alarms
Graph V-Gain
The vertical gain of the graph may be adjusted
using this control.
Valid Blocks (Diagnostics)
The temperature warning beep can be disabled by
setting the temperature alert in the Alarms menu
to Off.
This overlay shows the regions of the screen that
the unsteadiness process is using in its
calculations.
