4.5 Registration the Waypoint

When creating the destination by the use of the bearing and distance data in
(3) below, be sure to select great circle navigation in 4.5.3.5 "Switching be-
tween Great-circle and Rhumb-line".
If lhumb-line navigation is selected, it is impossible to enter the destination
using the methods in (3) below.
The equipment has a memory to store a total of 499 waypoints. The registered waypoints will not be erased
even when the equipment power supply is shutoff because they are backed up with the built-in battery.
Therefore, all the important position data such as the route or fishery data can be maintained under any
circumstances. Each waypoint can be identified and managed with the numbers of 001 to 499. Note that the
waypoint memory for 400 to 499 is used commonly with the event memory.
Following any one of the three steps described below can set the waypoint.
(1) Method to directly store to current position (event)
Pressing the EVENT key directly stores the current position when passing by a fishery or buoy.
The waypoints entered with the event function are stored starting from #400 to #499 in the chronologi-
cal order. Note that the used memory locations will be skipped.
(2) Method to enter the latitude and longitude
Directly enter the values read from the chart or the latitude and longitude obtained from other navigation
information.
(3) Method to enter the bearing and distance from the current position
Only when great circle navigation "4.5.3.5" is selected for navigational calculations, the destination can
be enter using the bearing and distance.
The equipment will automatically calculate the latitude and longitude of the waypoint if the bearing and
distance from the current position have been entered to it.
Memo
We would recommend you to take a note on the waypoint numbers since there are as many as 499 waypoints
available with the equipment. Attachment 2-D "Table of Waypoints" will provide ease in accessing to it.
