USER’S GUIDE
1. RECORDING TO VCR
1) TIMELAPSE MODE
- Channel to be recorded is switched, whenever NEGATIVE SWITCHING PULSE
through SW OUT port of TERMINAL arrives from TIME LAPSE VCR. Therefore, the interval of channel
switching is determined by recording time of TIME LAPSE VCR. Since as the recording time increases, the
time interval between channels to be recorded becomes longer so that the probability of missing important
scene grows. Therefore the configuration of appropriate recording time is important.
- When ALARM occurs, the recording frequency of the alarmed channel is increased.
- If TIME LAPSE VCR is configured to very short time duration comes under REAL TIME MODE,
recording might be out of order, and there might be some channels that are not recorded.
2) REAL TIME MODE
- If TIME LAPSE VCR is configured to time duration comes under REAL TIME MODE, channels are recorded
in order in tape by FIELD SWITCHING of 60 fields/sec for NTSC, and 50 fields/sec for PAL.
- When ALARM occurs, the recording frequency of the alarmed channel is increased by recording weighting.
- If TIME LAPSE VCR is configured to time duration comes under TIME LAPSE MODE, recording might
be out of order, and there might be some missing fields in recording.
2. PLAY BACK RECORDED TAPES
- When you play back tape using TIME LAPSE VCR, you have to choose appropriate
PLAY TIME of TIME LAPSE VCR for the precise search of desired picture. If you play back tape, which
recorded in long time mode, in short time mode, scenes will pass by so fast that you may not find desired
scene easily. Therefore, search videotape for desired scene, changing time mode appropriately.
- To play back videotape, press PB THROUGH key to see playback signal status of TIME LAPSE VCR,
and adjust pictures so that vertical turbulence and noise bar is not be displayed using + and - TRACKING
buttons.
- Manipulate LIVE/PB key to turn off LED. Then video signals from each channel are displayed in order on the
corresponding location in QUAD screen. To stop and see a standstill image, press FREEZE key, or
PAUSE/STILL key of TIME LAPSE VCR.
- When playback is suspended using PAUSE/STILL key of TIME LAPSE VCR, you can view output from the
VCR in the monitor using PB THRU key.
- Even if current screen is standstill by pressing FREEZE key, tape is being played back continuously.
Therefore, the screen will display images of time passed when the frozen screen is released. To see missing
images, you have to rewind the tape.
- Channel without signal is displayed by black screen during playback.
If the signal of a channel is missing during playback, the standstill image of last screen of the channel is
displayed.
The standstill screen turns to black screen when the channel is selected again by pressing channel key and
there is no signal at that time.
