The CHARTS IN DATABASE screen displays a list of all the
charts in the chart database (if there aren't any charts loaded,
this screen will be blank). To the right of the SCALE column is
a red vertical slide bar, which is relative to the size of the list of
charts in the database. The smaller the slider, the larger the
list; the larger the slider, the smaller the list. The slider also
indicates your relative position in the list.
Deleting charts
To delete one or more charts, first you must mark each
individual chart for deletion. The chart deletion function is
accessed from the CHART INVENTORY screen.
Whenever you delete HCRF charts, the permits for those charts
remain on the system.
1. Press the STAR key until you reach the SETUP MENU
screen, then press the CHART INVENTORY key.
2. Press the DELETE CHARTS key.
