Getting Started
Reviewing/Creating
Map Waypoints
You’ll now have a clearer picture of the route you are navigating. Keep in mind that when you
exceed the usable range of the built-in database or the optional MapSource or BlueChart data in use,
the range fi eld displays ‘overzoom’ to indicate that you should exercise extreme caution using the map
data. Press the ZOOM IN key to zoom into the 2 nm scale. Now that you’ve zoomed in a little closer to
your route, you can pan ahead of your vessel with the cursor to review map items and create on-screen
waypoints. Move the cursor to highlight the ‘TOUR3’ waypoint— just use the ARROW KEYPAD to
move the cursor as close as possible to the waypoint (To move the cursor in small increments, try a
series of short key presses).
Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint symbol and name
are highlighted. The data fi eld at the top of the map displays the waypoint name, the range and bearing
from your present position, and the coordinates for the waypoint.
To review the waypoint page for a selected waypoint:
1. With the waypoint highlighted, press ENTER.
2. To return to the Map Page, press ENTER again or press QUIT.
The cursor can also be used to create new waypoints right from the map display.
To create a new waypoint using the cursor:
1. Use the ARROW KEYPAD to move the cursor as close as possible to the following position:
N35º 02.914; W 076º 26.152’ (Use the data window to verify the cursor position.)
2. Press and release the ENTER/MARK key to capture the cursor position. Do not hold the button
down, as doing so marks your present position, not the map position.
3. Use the ARROW KEYPAD to highlight the waypoint symbol fi eld to the left of the waypoint name/
number.
4. Press ENTER to access the symbol page.
5. Use the ARROW KEYPAD to select the ‘Shipwreck’ symbol and press ENTER to confi rm.
6. Highlight ‘OK’ and press ENTER again to fi nish.
The waypoint ‘highlights’
when the cursor is moved
over it.
Waypoint numbering starts with
001 and continually counts up,
even if the waypoint name has
been deleted.
