Waypoint name
– a name can be added to each waypoint for easy identification.
WPplot
– instant storage of actual position as a waypoint.
XTE
– Cross-Track-Error (-Distance), measured magnitude of the position error
perpendicular to the intended track.
Radar section:
Cursor EBL
- can provide an image on the radar display which will determine
the risk of a collision if you continue on the proposed course line. The bearing
and distance from ship’s position to cursor position will be displayed in the top
line of the screen.
Cursor feature -
The cursor appears on the display as a large (+) character.
To activate the cursor, just press the cursor key. The cursor may now be
positioned by using the cursor key. When the cursor is set to a position on the
screen, the bearing and distance from ship’s position to cursor position will be
displayed in the top line of the screen.
)
To turn off the cursor, press CLR.
The chart cursor can be synchronized to the radar cursor, and thus be controlled
by the radar cursor in split screen operation.
EBL (Bearing mode) key
– the EBL bearings may be displayed in either
degrees Relative “R” or True “T”, depending on the selected orientation (HU,
NU, TM).
GAIN control
- adjusts the gain level of the radar’s receiver. The Gain control
level is usually set for the best target presentation with a slight noise speckle in
the background on the 12 or 24nm range. The Gain control level may be reduced
on shorter ranges to improve target definition as necessary and increased on
longer ranges.
Use some caution when adjusting the Gain control. If gain is set too low, small or
weak targets may be missed. If the gain is set too high on short ranges, the CRT
may become excessively covered with noise speckle making target observation
difficult.

On the longer range scales (24nm or greater), the sea clutter control may be
