SW-D7000U, 9CH. COLOR VIDEO MULTIPLEXERJVC PROFESSIONAL, IMAGING PRODUCTS 25NOTE: The title colors and positions in Play mode can be different to those in Live mode.The unit will keep a separate record of the selections for Live and Play.3.3.5 PLAY MODE: SEQUENCING DURING PLAYBACKDuring the Play mode, the multi-screens and full-screens are sequenced according to thesequence list and dwell times programmed in the menus. (Refer to the descriptions in the Livemode section of the manual.)CAUTION: When sequencing the display during Playback, do not set the VCR’s Play speedsuch that the frequency at which any one camera is Played back off the tape isslower than the frequency that the sequence list will switch through cameras inthe list.Example:If the VCR is set to 48 hour mode while Playing back a tape with 9 cameras recorded, then a fieldfor any one camera will generally not be sent from the VCR to the multiplexer more often thatevery 5 seconds. If the sequence dwell time is then set to 2 seconds, there is a very goodchance that the display will not be updated with a field from VCR for the current camera in thesequence, before the sequencing switches to the next camera in the sequence list.Recommendation:Set the VCR to its 2hour speed when sequencing the displays during Playback.NOTE: Tapes being Played back may be from different sites or different setups, and mayhave nothing to do with the current Live setup of the unit. Hence, the multi-screensequencing option will sequence through only the cameras that are not already onthe multi-screen. Any video loss or disabled cameras setup or detected in Live orduring recording will be ignored.3.3.6 ADJUSTING PLAYBACK BRIGHTNESS AND CONTRASTThe SW-D7000U provides a simple front panel adjustment to digitally adjust the contrast andbrightness of the Playback signal from the VCR.
