Alarm Distance] - Furuno FS-1575 Service Manual

4.5.4 [4. ALARM DISTANCE]

There are cases where own ship cannot be involved in distress even though it received a
distance Distress alert.
Setting this submenu [4.ALARM DISTANCE] to "500NM" on the assumption of the
above cases makes it possible not to output an alarm sound even if a Distress alert is
received.
For example, the reception alarm will not sound when receiving any of the following
Distress alert messages in any sea area other than polar regions (within the latitude of
+/−70 degrees) and at a distance exceeding 500NM between the Distress ship and the
own ship.
However, popup messages will be outputted.
In sea areas outside the latitude of +/−70 degrees, an alarm sound and popup message
are forcedly outputted.
