2.29 Displaying Navigation
Data During Stand-by
Various navigation data can be displayed
during stand-by. A barometer is built in this
radar; atmospheric pressure appears, in
graph form, on the navigation data display
during stand-by. If your navigation aid can
output data in NMEA 0183 data format, your
vessel’s position in latitude and longitude,
the range and bearing to waypoint, speed,
course, date, time and cross track error may
be input to this radar, and be seen in the bot-
tom text area during stand-by. Further, with
video sounder input, depth may be dis-
played, both digitally and in graph form.

[ENT] key.

the [ENT] key.

Note 1: The depth display scale changes au-
tomatically with depth and the maximum depth
is 1,000 meters.
Note 2: The barometer display is updated
hourly, thus the data shown may not be the
latest.
CAUTION
The barometer and depth displays are intended
as reference. Any data displayed by them
should be used with extreme caution.
