This feature allows FM-4850 to automatically send a position request call at certain
intervals.
This feature must first be enabled from the "ACTIVATION" menu, then the vessel
addresses must be set from the "SELECT ADDRESS" menu.
Also, you can monitor the position of the selected vessel from the "MONITOR
POSITION" menu.
