Indices and chart enlargement
When the soft key ZOOM OUT is used, you
will see several frames appear on the chart.
These frames are called indices and they
show you what parts of the chart can be en-
larged in the current picture range. The ar-
eas circumscribed with smaller frames can
be enlarged, but the area enclosed by the
largest frame cannot.

Korea) showing indices
Remarks on chart display
A chart will not be displayed in the following
conditions:
• When the chart scale is too large or too
small.
• When scrolling the chart outside the indi-
ces.
When this happens, select proper chart scale.
