Finding Your Position Cold Start When the GlobalNav 310 is turned on for the very first time, it doesn’t know where it is, nor what the local time or date is. If you tell it your position, time, and date, the unit will take much less time to lock-on to the satellites and give you a fix or position.
The next time you use the unit, it should take much less time to lock on. To use your GlobalNav 310, first make certain you have a clear view of the sky, free from any obstructions such as trees, carport, or a covered boat dock.

NAV screens. WAYPOINTS The GlobalNav 310 gives you the capability of creating your own data- base of locations, called “waypoints”.. You can save your present posi- tion, cursor position, or enter a latitude/longitude and save it as a way- point.
Saving The Cursor Position as a Waypoint When the cursor is showing on the plotter and you press the WPT key twice, the GlobalNav 310 puts the cursor’s position into the first available waypoint number. A message appears on the display telling you the way- point number it just used.
Remember, the method of saving your present position and the cursor’s position is identical. Edit Lat/Lon The GlobalNav 310 lets you enter any latitude/longitude using the keyboard and save it under any waypoint number, from 1 to 250. You can also change any waypoint’s position using this method.
Edit Name The GlobalNav 310 also lets you assign a name to each waypoint. The name can have up to eight characters. To name a waypoint, first select the way- point number that you wish to name.
For example, moving waypoint number 2 to waypoint number 10 depos- its the name “WPT 2” in waypoint 10’s name field. DISTANCE BETWEEN WAYPOINTS The GlobalNav 310 can easily give you the distance between two user waypoints. To do this, first press the WPT key, highlight the “Wpt Options”...
