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 Switching the Cursor Data Box
On and Off on page 2-13.)
Day/Night
This option allows you to change the display between day and night modes.
If you select
NIGHT mode, a different palette, more suited to night time
viewing is used.
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).
