1.1 Functions

Attaching an optional GPS/DGPS receiver (GPS 100 or DGPS 200) makes it possible to turn the GPS
Navigator J-NAV500 into a GPS/DGPS navigational system. This navigational system uses GPS satel-
lites to calculate accurate positions anywhere in the world and under any weather conditions 24 hours
a day. This navigator displays navigational paths to entered waypoints using position data. There are
the following four navigation displays:
• POSITION
• NAVIGATION
• CDI
• PLOT
There is also a [STATUS] display showing status information such as satellite number, beacon fre-
quency and receiving level.
A total of 499 waypoints and 20 route plans can be entered in the navigator. A single press of the
key can turn any current location into a waypoint. Someone should fall overboard, press the
key for an instant graphic representation of that position and the route to return to this position.
