●Large LCD Display

Necessary navigational information can
be displayed on a large LCD screen at a
glance, ensuring simple operation without
troublesome switchover of displays.

●

More Accurate DGPS Positioning

Differential GPS position data is
automatically received in DGPS service
areas, and own ship's position fixes are
displayed with very high accuracy.

●Waypoint Memory

Up to 499 waypoints can be stored in the
internal memory with their place names in
8 alphanumeric characters.

●Data Outputs

Two data ports are provided: one is an
RS-422 port, and the format is selec­table from NMEA0180, NMEA0183
(version 1.5 or 2.1) and a JRC.

●Navigational Calculations

Navigational calculations are made in the
Great Circle or Rhumb Line mode.

●Loran C/A TD Display

The GPS position fixes can be converted
into Loran C or A time difference values
and displayed on the LCD screen.

●Relay Contact Output

A log pulse or external buzzer alarm
signal is available from the relay contact
output.

●Weather information display

Local weather and sea conditions in
coastal sea areas of Japan can be
