Raymarine e7 User Reference page 87

• If you have a Raymarine GPS receiver using SeaTalk or
SeaTalk ng , it will automatically correlate each time you change the
datum on the multifunction display.
• If you have a Raymarine GPS receiver using NMEA0183, or a
third-party GPS receiver, you must correlate it separately.
It may be possible to use your multifunction display to correlate
an NMEA0183 GPS receiver. From the homescreen go to Set-up
> System settings > GPS Set-up > View Satellite Status. If the
datum version is displayed, it may be possible to change it. From
the homescreen go to Set-up > System settings > Data Sources
> GPS Datum.
Note: Raymarine recommends that you check the displayed
vessel position in the chart application against your actual
proximity to a known charted object. A typical GPS has an
accuracy of between 5 and 15 m.
Chart cards overview
Chart cards provide additional cartographic information.
Obtain detailed cartographic information for the area that
you navigate using Navionics® chart cards. To check the
current availability of Navionics chart card types, please
visit www.navionics.com or www.navionics.it. The amount of
cartographic detail shown varies for different areas and for different
scales. The chart scale in use is indicated by a number and a
horizontal line in the status bar — the number represents the
distance the horizontal line represents in nautical miles horizontally
across the chart.
You can remove and insert chart cards while a chart is displayed
provided that you follow the correct procedure. The chart information
is retained on-screen until the chart application redraws the screen;
for example, when you pan outside the current area, or use the
Range control to change the chart scale.
Using the chart
Caution: Care of chart and memory
cards

from chart and memory cards:

to a chart card, as the charts may be overwritten.
