When ASR is on, the projector monitors the current input for horizontal
and vertical scan frequency changes. When a frequency change occurs, the
current Input memory and all Recall memories are scanned in search of a
memory with matching scan frequencies. If one exists, this memory
becomes the current setup memory. If a matching memory is not found, an
ASI is performed. ASI automatically adjusts display settings based on the
settings of other setup memories stored in the projector. The new settings
created by ASI are either a copy of the settings from another setup memory
which has matching scan frequencies or an interpolation between “the two
closest” setup memories.
ASR is also performed when:
• You switch to an input which has ASR set to On.
• You select a Recall memory and ASR is set to On for the current input.
• A channel is selected which specifies an input which has ASR set to On.
• The source frequencies are different than the frequencies in the setup
being selected.
When ASR selects a setup memory, a source message is
briefly displayed to indicate which memory was selected.
If the new memory settings (Input and Recall) match
that of one of the channels in the Channel List, the
matching channel is used and displayed in the source
message. Display adjustments, if made, are stored in the
new memory (unless it is locked).
If, on the other hand, an ASI is performed, a source
message is briefly displayed which includes an ASI
message to indicate the action taken. If an Input
memory with matching scan frequencies was found by
ASI, its settings are used and its identity is displayed. If
an interpolation was performed, the two setup memories
selected for the interpolation are displayed and the
resulting settings are used. If adjustments are made to
settings created by the ASI feature, the new settings will
NOT be saved in the current setup memory; a message is displayed to indi-
cate this. To perform an ASI and have the adjustments saved in the current
setup memory, press to select the ASI with Save utility.
Note: To avoid selection/use of the current Input memory settings when it is
desired that Recall memories be ASR selected when a source change occurs,
clear the current Input memory ()to reset its scan frequency settings
to null values, then immediately lock the memory ()so that its settings
cannot be modified.
