FLASHBACK OPERATION, CONTINUED
For example, after the scan has initialized, the operator finds a scene of interest. If the
operator invokes the flashback command, the scan stores the current scene (Scene
A). If the operator moves on to another scene (Scene B), then invokes the flashback
function, the scan returns to Scene A. While at Scene A, if the operator invokes the
flashback function, the scan returns to Scene B. The toggle pattern repeats
indefinitely until the operator moves the scan to a different scene (Scene C). While at
scene C, the operator invokes the flashback command, the scan goes back to the last
scene viewed when the flashback command was invoked. If the flashback command
is invoked again, the scan returns to scene C.
The only exception is during a VectorScan operation, for example, if the Flashback
function is invoked and the scan returns to scene A. After that, a VectorScan is
started. During the VectorScan, the scan moves from PreShot 2 to PreShot 3. If the
flashback is invoked while the scan is at PreShot 3, the VectorScan will be terminated
and the scan will go back to PreShot 2. Each time flashback is invoked thereafter, the
scan toggles between PreShots 2 and 3 until the scan is manually controlled. After
that, the flashback feature returns to normal operation. The next time the Flashback is
invoked, the current scene (Scene D) is stored and the scan returns to the last
Flashback scene (in this case, Scene A) prior to the start of the VectorScan. Once at
Scene A, if the flashback command is invoked, the scan goes back to Scene D.

PRESHOTS
When a scan unit receives a command to go to a PreShot, if it has not already found
its home position, the unit goes to its home position first, then performs the PreShot.
The scan unit goes to the pan, tilt, zoom, and focus positions programmed in the
PreShot.
While a scan unit is going to a PreShot position, the character generator adds the title
of the PreShot to the video signal and adds the letter A (automatic) with the camera ID
to the video signal. The PreShot title and the letter A remain on the video until the
scan gets another command. When the scan is being manually controlled the letter M
(manual) is added to the camera ID.
If:
PreShot title ON
Camera ID title ON
Operator sends the scan to a
PreShot that has not been
programmed
The KD6i has a Still PreShot feature that can be enabled or disabled.
Refer to
Rev. D
Section 5.5.5
for enabling and disabling the Still PreShot feature.
Then:
PreShot title is displayed.
Camera ID and the letter A or M are displayed.
The message "DOES NOT EXIST" is displayed
on the video.
