Marquee 8521 Ultra Green (HUD) User's Manual
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 indicate 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] [2] ) to reset its scan frequency settings to null
values, then immediately lock the memory ( [UTIL] [1] [2] ) so that its settings
cannot be modified.
When to use the ASR feature...
The ASR feature is intended for use when many different sources must share the same
input (via a third party switcher, for example) or when a signal source can output several
different scan frequencies (e.g., a SVGA card).
Example
A system has six different sources. Source "A" is a video camera. Source "B" is a VCR.
Sources "C" through "F" are various computers. All sources are connected to a 3rd party (non-Electrohome)
signal switcher. The switcher is connected to projector slot 1. For each source, a Recall memory is created to
store its display settings. No two sources have the same frequencies.
[UTIL] [1] [4] is pressed to turn on the ASR feature for the projector's slot 1 input. When ASR is on and a source
is selected by the switcher, the projector automatically adjusts its display settings for the new source by switching
to the Recall memory set up for that source.
3.6.1.3.2 Clear Channel Setup [UTIL] [1] [5]
This utility is used to clear the current setup memory to the factory default display
settings.
To clear the current setup memory, press [5] from the Source Setup menu. A dialog box
is displayed. Move the cursor to "Do It" then press [ENTER] to clear the memory. If you
press [ENTER] with the edit cursor on "Cancel", the clear operation is not performed.
When the clear operation is complete, the Source Setup menu is returned.
Note: Note: Clearing a setup memory does not "delete" it from the system. If the projector's 80 memory
spaces are used up, and you need to delete unused memories to make room for new memories, call
your dealer for assistance.
3.6.1.3.3 Select Internal Frequency [UTIL] [1] [6]
This utility allows you to use the projector's internal signal generator. The
internal signal generator is provided to assist users and technicians during
projector setup. By using the internal generator, a setup memory can be
adjusted for a particular set of horizontal and vertical scan frequencies
without requiring an external source. Six preset horizontal and vertical
frequencies are provided.
If one of the preset frequency sets closely match a source you will be using,
you can set up an Input or Recall memory for the source before it is
available for connection to the projector. When the source becomes
available, few adjustments will be required. Another reason to use the internal generator is to improve the
accuracy of the ASI feature. By setting up various memories at different scan frequencies, ASI has more
information to choose from when making interpolations between setups.
To select an internal frequency, press [6], "Select Internal Frequency" from the Source Setup menu. The resulting
menu allows you to choose the scan frequencies of the internal generator. Select one of the displayed items.
