Use BNC pigtail adaptor to connect NTSC or PAL compatible cameras. See Figure1-3; the
position and numbering of the on-screen camera output is determined by the slot and channel
numbering sequence of the cards. For example, camera 1 would be connected to channel 1 of
card 1, camera 2 would be connected to channel 2 of card 1, camera 5 would be connected to
channel 1 of card 2, etc., since there are 4 available channels per card slot.

not contain a diskette, and there are no discs in the CD / CD-RW drive; if there are any discs, press the
eject button to eject an inserted disc.
