Auto Memory
The DVS 304 stores 16 auto memories with input and picture control data for each input.
The default settings enables these memories to automatically recall input and picture
controls for signals that have been previously applied. By disabling auto memories, the
DVS 304 will treat every newly applied input as a new source. Default is

the desired setting (4x3 or 16x9) can be made in the input config menu by adjusting the
aspect ratio setting. If auto memories is enabled, then this setting is saved and recalled
the next time the signal is detected.
It is strongly recommended that the aspect ratio mode setting be used on initial setup of
the DVS, or input rates that have not already been saved as auto memories may not be
displayed as expected. This can be overcome by clearing the auto memories on the input
in question, and is done by holding in the front panel
button simultaneously for four seconds. Alternatively it can be cleared on a rate by rate
basis by applying a one-time auto image.
"New" signals/rates that have not been previously detected by the
DVS 304 are initially set-up using default parameters, then auto
image
is automatically applied and values stored. The next time that
signal is
detected, the values stored in the auto memory location are ap-
plied.
"New" signals/rates that have not been previously detected by the
DVS 304 are set-up using default parameters. If one or both
manual input and picture settings are made to the input, an auto
memory location is
created and recalled each successive time the input is detected.
Each change in input sync triggers an automatic auto image.
When auto memory is disabled, each change in sync is treated as
a new signal and
an automatic auto image is triggered. Any manual changes made
to the
image and picture controls are lost each time a new rate is de-
tected.
Each change in input sync causes default values to be applied
to the rate. Any manual changes made to the image and picture
controls are lost when a new rate is applied.
