value in the status bar.
Cursor Readout
This option controls whether the cursor data is shown in latitude and
longitude or in range and bearing. Alternatively, you can show both types
of readout, in separate boxes, or turn the cursor data box off.
You can also turn the cursor readout box(es) on and off during normal
operation, via the
SCREEN
default soft key (see Chapter 2) .
Day/Night
This option allows you to change the target presentation between
DAY
and
NIGHT
modes.
In normal day presentation, black targets are displayed on a white
background. If
NIGHT
presentation is selected, the image is reversed, so
that white targets are shown on a black background to reduce the intensity
of the image.
Help
When Help is set to
ON
, a prompt appears in place of the status bar when
selecting a soft key or menu choice and when using the context-sensitive
cursor. The help message is cleared when an action is selected.
Soft Keys
When the Soft Keys option is set to
ON
, the default soft keys are displayed
if no other operation is in progress.
When the Soft Keys option is set to
OFF
, the default soft keys are only
displayed when a soft key is pressed and they disappear if no operation is
performed for 10 seconds.
Key Beep
This option controls whether or not the keys sound when pressed.
Note:
The alarms continue to sound.
MOB Data
This option controls whether
MOB
data is based on GPS data, or on dead
reckoning (
DR
). Dead reckoning normally provides a better indication of
the course to an object in the water, on the assumption that your vessel
and the object are both subject to the same tide and wind effects.
