•
Alarms:
The alarms that can appear in connection with the radar operation,
are:
- Guard Zone alarm
- Rotation lock alarm (check connection to scanner)
- Trigger fail alarm (check connection to scanner)
- Heading missing alarm (check connection to compass)
- Communication failure alarm (check connection to scanner)
- Communication time-out failure alarm (no communication
between display and scanner)
- Bearing zero alarm (check if scanner is rotating)
- Bearing pulse alarm (check if scanner is rotating)
•
Off-center mode
– permits the operator to obtain a greater view
in the direction of interest. Place the cursor within 2/3 of the dis-
play and press the [0] key. The ship’s position will now be moved to
the cursor position and thereby increasing the desired area of view.
To deactivate the Off-center mode, press [CLR] and [0]. This will
replace the ship’s position back at the center of the display. If the
radar system is turned off while the Off-center mode is on, at next
power up the offset mode will still be on.
•
PLOT function
– will require that a heading sensor (Gyro or Com-
pass) is connected to the CRXX. If so, then you can plot the actual
cursor position on the radar display by pressing the [PLOT] key from
the radar display, and thereby save the position in the WP-list as a
waypoint i.e. you can give the plotted waypoint a new name/number,
symbol, color, etc.
•
Radar colors
- There are several color settings to choose from for
the radar display. See Palette setup ([MENU],[7],[4]).
•
Range rings
- The extension of the range depends on how power-
ful the connected radar antenna is. There are several ways of adjust-
ing the range on the screen, the quickest way is:
1-9
Use one of the shortcut keys to quickly go to a different range:
Press [1] = 0.125 nm [2] = 0.25 nm
[3] = 0.50 nm
[4] = 0.75 nm [5] = 1.5 nm [6] = 3 nm
[7] = 6 nm [8] = 12 nm
[9] = 24 nm
