(RNG/BRG) data boxes. The current units are shown for the heading 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.
