of the VCR, typically this is to check VCR output or settings.
To select the VCR as input, press FUNCTION (F) and then press PLAY. On Monitor-A you
will see the multiplexed video images as they are being output to the VCR for recording.

always reverts to Live mode.
VCR Playback Speed:
The programmer must select the Playback speed on the VCR, and not on the SW-D8000U. There
is no related setup required on the SW-D8000U during Playback.
The SW-D8000U will automatically adjust its display to match the VCR Playback speed.

which the data was recorded is displayed after the "P".
example 24 hour mode) tells the programmer the speed at which the tape was recorded. It does
not indicate the speed at which the tape is being played back. To find out the Playback speed, the
programmer must look at the VCR's Playback speed indicator.
If the recording was made using the camera switch VEXT input , then the mode and speed indicator
will read 'P EXT' in Play mode. The time and date is displayed on-screen during Play mode. Note
that this is the recorded time, not the current system time. The indicator 'V' will be displayed in the
corresponding camera image if there was video loss at the time that the recording was made.
The SW-D8000U will display the text 'N/A' if a camera is not detected on tape for 8 or more
consecutive cycles during Playback. And if it is not flagged as a video loss camera the warning
message 'N/A' will display signifying that it is Not Available. This is a warning message only, and
can appear during Playback on full-screen or multi-screen formats on Monitor-A.
Several circumstances can cause the 'N/A' indication:
q The camera may not have been in the record list at the time of recording.
q The camera may have been disabled at the time of recording.
q
The images for that camera on tape have been corrupted and cannot be decoded at time of
Playback.
q The VCR Play speed is very slow.
This indicator helps the operator to tell the difference between images that are not being updated
during Playback and images that are being updated from tape but have no movement within the
image.
The indicator 'A' will be displayed with the corresponding camera image on Monitor-A if there was
an active alarm at the time that the recording was made.
