Zooming in and out on the chart view
To zoom in and show a more detailed view of the chart, press
the IN key located in the lower right-hand corner of the

press the OUT key located next to the IN key.
Obtaining detailed chart data
For detailed chart data, you should obtain either ChartKit BSB
chart CDs from MapTech or NDI, ChartPack BSB chart CDs
from Maptech, or HCRF chart CDs from the United Kingdom
Hydrographic Office (UKHO). With these choices in
cartography, the 961/962 provides you with truly worldwide
chart coverage. (If your vessel ever moves into an area that
isn't covered by the charts installed, the 961/962 will
automatically display a plotter grid.) For information on
obtaining BSB or HCRF (ARCS) charts, see "Purchasing charts"
starting on page 13-37.
For further details about using these charts, see "Navigational
chart CDs" starting on page 2-5.
If you're using BSB charts, make sure you use Maptech Chartkit's
Second Edition (or higher) BSB-format chart CDs (or anyone else's
BSB-formatted 2.0 CDs). If you try to install one of the First Edition
CDs, you'll receive an error message, and will be unable to
complete the installation.
