FLASHBACK OPERATION, CONTINUED
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.
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, and then performs the PreShot.
The scan unit goes to the pan, tilt, zoom, and focus positions programmed in the
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.

PreShot 99 is reserved for manually controlling the NightShot mode on camera model
numbers 843216-1011, 843216-1013, 843216-0984, and 843216-0985. PreShot 99
toggles between standard operation and the NightShot mode. The NightShot mode
must be in the manual mode for this PreShot to function. (Refer to
the NightShot in manual mode.) The NightShot mode causes the camera to pull the IR
block filter and automatically go to black and white to increase the sensitivity of the
for enabling and disabling the Still PreShot feature.
Video is frozen between PreShots. Video from the old position
remains until the scan arrives at the new PreShot, then switches to
the video from the new PreShot. While video is frozen, an asterisk
(*) appears on the same line as the Camera ID.
