Indices and chart enlargement
When the ZOOM OUT soft key 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 enlarged in the
current picture range. The areas circumscribed
with smaller frames can be enlarged, but the
area enclosed by the largest frame cannot.

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 indices.
When this happens, select proper chart scale.
