The system supports Day-1, Day-2, Day-3, Night and Time
service modes. Attendant programming can be used to change the system operating mode. The
three Day modes are designed to cover a 3-shift 24-hour workplace. Changing modes between
Day-1 and Night can be easily accomplished by using a Night-switch key programmed on the
attendant's or alternate attendant's keysets.
The Time mode initiates Day-1 to Night (and Night to Day-1) mode
change-over at times specified in system programming. The time is programmable on a
per-weekday basis and can be easily changed using attendant programming.
