Chapter 7: Setting Up the System Defaults 127
Day/Night
This option allows you to change the target presentation between day and night
modes.
In the normal day presentation, black targets are displayed on a white
background. If you select
NIGHT
presentation, the picture 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 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 make a noise when you press them.
MOB Data
This option controls whether MOB data is based on position 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.
Menu Timeout Period
With no timeout set, menus and soft key labels remain displayed until you clear
them by pressing
ENTER
,
CLEAR
or the appropriate dedicated key.
If you set a value here, the menus and soft key labels will be cleared if a key has
not been pressed for the specified number of seconds.
This setting does not affect the default soft key labels, which are controlled by
the Soft Keys option (see above).
