3.5.17 DISPLAY DEFINITION DURING POWER ON SEQUENCE

This section defines the display definition during the NAV 2000R power-up sequence. During power-up,
the NAV 2000R initializes the display screen and displays the JCAIR symbol and "NAV 2000R" using
large sized characters while it executes a self-test diagnostic. The diagnostic test results will be
displayed under the heading "SYSTEM DIAGNOSTICS......" as the self-test proceeds. If all self-tests are
passed, a second screen will display. If any self-test fails, the fail test flashes, as a notification to the
operator. After a failed self-test, the operator must press the ENT key for the unit to proceed. On the
second screen, which remains for approximately seven seconds, the current software version status of
both the CPU and DSP boards is displayed. Following this screen, the NAV 2000R will enter normal
operation, as defined by the unit configuration.
3.5.18 STORING & RECALLING SETUPS
The NAV 2000R has the ability to store and recall up to 49 different NAV 2000R conditions. All NAV
2000R selection options are stored to memory for later recall. The store function saves current NAV
2000R status, configuration setup, system mode of operation, field data, and the current page and field
selector positions.
This means that all entries of the six primary modes: VOR, LOC, G/S, ADF, MKR, and COM, and the
secondary modes: EMM, VORa, and LOCa are stored.
Current NAV 2000R conditions are stored by pressing and releasing the store, STO, key (while not field
editing or entering). A pop up menu prompts for storage register number. The storage register number is
entered using the numeric keypad and is a number from 1 to 49.
Previously saved NAV 2000R test setups are recalled by pressing the RCL key. A pop up menu prompts
for the storage register number. The storage register number is entered using the numeric keypad and is
a number from 1 to 49.
Following a recall, the NAV 2000R will remain in its current SELECTED MODE with the stored field data
updating the previous setup. Selection of a different mode will then select that selected mode's recalled
field data. Therefore, nine test setups, one of each operating mode, are stored and recalled for each
register number.
If a setup is stored or recalled, this will continue to be displayed on the status line until a field is modified.
Recalling register 00 sets all NAV 2000R fields to factory default settings. Storage to register 00 is not
possible.
Also, if the LOC/GS mode button is pressed while the recall "pop up" window is displayed, an ILS
frequency pairings help screen will appear.
