ASI with Save ASI Automatic Source Interpolation is a feature which automatically adjusts display settings based on the settings of other setup memories stored in the projector The ASI with Save utility performs an immediate ASI on the current source and saves the resulting display settings in the current setup memory The new settings are created by either copying the settings from another setup memory which has matching scan frequencies or by interpolating 3 32 rr GJ B Woe OPERATION between the two closest setup memories This feature is very useful when adding a new source to the system and or when much adjustment is required By using the ASI with Save feature the projector can do most of the required adjustments for you To perform an ASI with Save press 2 from the Source Setup menu A dialog box is displayed AST WITH SAVE Press 4 to move the cursor bar to Do It then press iarna Curra Exa New display settings will immediately be setup wil be lost calculated and saved in the current setup memory The only exception is when the current setup memory is locked If locked display settings will not be modified If Cancel is selected from the dialog box the operation is stopped For more information about the ASI logic process refer to Appendix C ASR ASI Logic Diagrams Notes about the ASI feature ASI works better when there are many setup memories in the system For example if you a

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 3 33 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 hae 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 Selected Memory 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 PUR me with matching scan frequencies was found by ASI its ASI 5

The projector has 80 setup memories which store display settings Multiple setup memories are needed because display settings are usually different for different sources For example the display settings brightness contrast convergence etc when using a VCR may be very different than the settings 3 13 OPERATION Input Memories gt Recall Memories gt 3 14 for a high resolution computer output When display adjustments are made the new settings are automatically saved in one of the projector s setup memories There are two types of setup memories Input and Recall Both memory types store the same parameters The only difference is that Input memories store display settings for a particular physical input e g switcher 0 slot 1 while Recall memories can be used with any input At any one time one setup memory is the current setup memory The display settings in the current setup memory are used for the current display When a source is selected by entering its input number the Input memory for the selected input becomes the current setup memory unless ASR is on and is triggered If a Recall memory is selected it becomes the current setup memory Display adjustments are automatically saved in the setup memory which is current at the time of adjustment unless the setup memory is locked explained later As mentioned above Input memories store display settings for each physical input e swit
