6.4.2.1 Bearing Indication Hold Time
The “bearing indication hold time” defines how long the bearing value is indicated after the
signal fell under the squelch level.
If there is no more valid bearing information available, the last bearing data (bearing arrow,
life values and digital bearing display) is displayed on the “Bearing” page for a defined period
of time. This time is set to 2 seconds by default and configurable via this setting.
By pressing the “OK” button or the hotkey “Edit Value” (s. Fig. 80, positions 4 or 8), the
following dialog is opened.
Setting to
“Endless” (last
bearing is shown
until the next

o
The new value for the bearing hold time can be entered in the input field “New Setting”,
using the numeric keys of the keypad.
o
Use the hotkey “Endless” to set the bearing hold time to an “endless” value, which
means that (after the signal was interrupted) the last valid bearing information will be
shown as long as the new valid bearing needs to arrive.
o
To set the bearing hold time to the default value (2 s), press the hotkey “Set Default”.
o
For the final confirmation, press “OK” or use the “ESC” button to leave the dialog
without adopting the new value.
6.4.2.2 Bearing Reference Direction
The bearing reference direction is significant for the bearing indication. The direction of the
bearing arrow in the 360° display (and compass rose indication) is always referred to a
defined point in space.
This reference point can be the
magnetic
north position,
true
north position and
relative
(reference is the direction to the vessels bow). For further explanation refer to chapter 6.1.2.
Pressing “OK” or “Edit Value” (s. Fig. 80, positions 4 or 8) while the line “Bearing Reference
Direction” is marked opens the corresponding dialog.
