b) HIERARCHY
The setting and actual value messages are arranged hierarchically. The header display pages are indicated by double
scroll bar characters (), while sub-header pages are indicated by single scroll bar characters (). The header display
pages represent the highest level of the hierarchy and the sub-header display pages fall below this level. The MESSAGE
UP and DOWN keys move within a group of headers, sub-headers, setting values, or actual values. Continually pressing
the MESSAGE RIGHT key from a header display displays specific information for the header category. Conversely, contin-
ually pressing the MESSAGE LEFT key from a setting value or actual value display returns to the header display.
