4.2.6.1-2 Coding Dimension Discriminability

Each level of a coding dimension should be easily and readily distinguishable from the other levels.

Additional Information:
For example, if color is used, the different colors should be easily discriminated. Each color should have a single, precise meaning that is consistent with applicable population stereotypes. A formal coding scheme that encompasses all coding methods (e.g., color, shape, brightness, textures/pattern, and flash rates) and specifies a hierarchical order should be established and formally documented. Alarms should be organized into categories according to priority. Coding should be systematically applied such that alarm information with the highest priority is also most prominent.
