Marking and Saving Waypoints
Knowing your present position is only part of any
navigation equation. You also need to keep track of
where you’ve been and where you are going. Waypoints
serve as electronic markers that let you keep track of
starting points, destinations, navaids and any other
important position.
The GPSCOM 170 allows you to mark, store and use
up to 250 waypoints. A waypoint position can be entered
by taking an instant electronic fix or by manually enter-
ing a coordinate or range and bearing in reference to an
existing waypoint. If you try to mark a waypoint without
having a position fix, you’ll be notified with a ‘No GPS
Position’ message.
To mark your present position:
1. Press
K
to capture your position.
The mark position page will appear, showing the cap-
tured position and a default 3-digit waypoint name.
To change the default position name:
1. Press the up arrow key twice to move the field high-
light from the ‘SAVE?’ field to the name field.
2. Press
E
to begin entry of the name. Pressing the
left arrow key will clear any existing data.
3. Use the arrow keypad to enter a value in the appropri-
ate character field, and to move to each
character position.
4. Press
E
to confirm the waypoint name. The field
highlight will move to the ‘route number’ field.
