The Vision 21 is easy to operate and requires minimal training. The layout of the System Processor keypad is logically grouped and makes use of colored keys to highlight frequently used functions. The displays are highly visible with a viewing angle of 150°, unlike the limited viewing of most LCDs.
Operating procedures are structured in an organized hierarchy. This, along with activity summaries appearing on the display, eliminates the need for memorizing arcane codes and procedures.
Up to twenty operator login names and passwords are stored in the System Processor. Various operator activities may be password protected by the three password levels.
The System Processor may operate in one of two modes; Dispatch or Logging Mode. Dispatch Mode sets the Vision 21 as the primary call processing center. Logging Mode sets the Vision 21 as a decoding center with call information passing to another device through an RS-232 cable. This allows the primary processing to be done on a computer with greater database capabilities.
Built-in diagnostics target hardware problems in both the Vision 21 and remote Master Boxes. Common hardware problems, such as a low battery or disconnected cable between modules, are continuously monitored. Master Box troubles and missing self tests are tracked by the System Processor, reducing maintenance time.
