Check the
Input memory of the
currently selected input for
matching H & V scan
frequencies.
match
yes yes
no match
Change the current
setup memory to the
matched Input memory.
no
Do nothing.
A change in scan frequency is detected.
The change is greater than 100 Hz horizontal
or greater than 1 Hz vertical.
Is ASR
set to On for the
currently selected
input?
no
Switch to the selected
source and/or setup
memory.
A source, Recall memory, or channel was manually
selected. The H & V scan frequencies of the source
do not match that of the selected setup memory.
Is ASR
set to On for the
selected
input?
Search for a
Recall memory with
matching H & V scan
frequencies.

Use the display settings
of the matched Input
memory but do not update
the current setup memory.
Create new display set-
tings by interpolating the
two closest setup mem-
ories (in freq.). Do not
update the setup memory.
