OPERATION
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).

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 UTIL 1 2 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 ( UTIL 1 5 ) to reset its scan frequency settings
to null values, then immediately lock the memory ( UTIL 1 3 ) so that its settings cannot be modified.
