4.17 Entering Waypoints
Waypoints can be entered in one of the following four ways:
• Using to store a waypoint
Press when you pass a fishing point or buoy and enter the desired waypoint number. (See
Section 4.11, “Entering current position as a waypoint [EVENT].”)
• Entry of latitude/longitude (When the [L/L] is selected.)
Direct entry of latitude/longitude coordinates from marine charts or other navigation informa-
tion.
• Entry of Loran C time difference(When the [T/D] is selected.)
Direct entry of Loran C time difference TD1 and TD2. (For those who are used to time difference
data)
• Entry of bearing and distance
Direct entry of bearing and distance from current position of the ship can be calculated.
Up to 499 waypoints can be entered which are numbered from 001 to 499.
To store new numbers and to recall old ones, a number must be entered.
Thus it is a good idea to record the waypoint number and waypoint name in the waypoint list in Appendix
E. (Or in a copy of this list.)
The following function can be used to look for a registered waypoint.
• Sorting the waypoint list in number order (default) or in alphabetic order.
(4) Waypoint symbol
It is possible to display the first letter of the waypoint name as a waypoint mark on the display.
This display function can be turned on and off.
