3.6 Entering Waypoints

3.6.1 General Waypoint Information

One of the key operations of the
pre-programmed waypoint destinations from your present position. Way-
points can be entered into your 398 unit by using one of the following four
methods:
Storing au "Event" (instantly saves ship's present position as you pass
l
a buoy, enter a channel, or are sitting on top of a great fishing spot).
Direct entry of Latitude/Longitude coordinates taken from marine
l
charts or light list, etc.
Direct entry of Time Difference (TD's) coordinates. These are usually
l
from a chart or a friend's loran.
By using Range and Bearing from your present position.
l
The
398 has 500 internal waypoint memories for storing waypoint
NAV
position coordinates. These memories are numbered from #OOl to 499.
Whenever you decide to enter new waypoint position data, or recall old
entered first. This is necessary so the
information from the correct memory.
Since there are so many waypoint memories, it's usually a good idea to
make a paper log of your stored waypoint data. The log should include the
Name of the waypoint, its Memory #, L/L and TD coordinates, the source of
the position data, and may be even the normal bearing and range from your
slip.
Some owners use certain numeric blocks of the memory locations to store
certain waypoint groups that make up trips or route plans. In this way, favorite
trips are saved and used over and over again by the number grouping selected.
Of course, the paper log book helps keep things straight for everyone.
