Time Lapse VCRs
The time-lapse VCR reduces the number of cassettes required for a site. It also reduces the amount of time
spent changing cassettes and the amount of storage space required for them. Time-lapse VCRs record and play
tapes more slowly by recording fewer images. The speed of operation for a normal VHS VCR is 3 hours. The
table below gives examples of how many fields can be recorded on a three hour tape per camera in various time-
lapse modes.

THE MENU SYSTEM
More advanced operation of your multiplexer involves use of the menu system. Your multiplexer provides user-
friendly, on-screen menus for entry of user data such as titles and for the selection of options (see the Programming
Reference manual for details).
Note that the alarm key is disabled while the menu system is active.
