3.6 Entering Waypoints

3.6.1 General

Information

One of the key operations of the

NAV

398 is to guide you to planned or

pre-programmed

destinations from your present position.

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

a buoy, enter a channel, or are sitting on top of a great fishing spot).

Direct entry of Latitude/Longitude coordinates taken from marine

charts or light list, etc.

Direct entry of Time Difference

coordinates. These are usually

from a chart or a friend’s loran.

By using Range and Bearing from your present position.

The

NAV

398 has 500 internal

memories for storing

position coordinates. These memories are numbered from

to 499.

Whenever you decide to enter new

position data, or recall old

information, the

memory location number has to be

entered first. This is necessary so the

NAV

unit can place or retrieve the

information from the correct memory.

Since there are so many

memories, it’s usually a good idea to

make a paper log of your stored

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

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.
