details.

coordinate grid (when Grid is set to AUTO (default) in chart setup),
depending on the actual scale - see section 3.4 Chart setup for more
details in regard to what can be shown on the chart and what you

can be zoomed up/down in six steps, from

enables you to zoom beyond the chart,
which automatically is switched off and replaced by a lat/long coor-
dinate grid. In this mode, the scale can go down to 1:600.
