Distress Calls - Simrad RS90 Operating Manual

Distress calls

DSC is particularly useful for sending distress signals to all stations.
The process is automated to the extent that if you are under stress,
you can simply press a single, dedicated distress button—the red
button beneath the red cover on top of the RS90 handset.
When sending a distress call, the DSC radio automatically transmits
as much information as is available, including:
•
The MMSI of the ship in distress;
•
The position of the ship in distress; (If the radio is connected to a
GPS);
•
The nature of the distress.
¼ Notes
•
Before the DSC functions can be used, you must enter a valid MMSI
into the RS90 radio. See "Entering or viewing your individual MMSI"
on page 84.
•
If the small DSC icon is not displayed on the standby screen,
DSC may have been turned off in settings. See "Enabling DSC
functionality" on page 87.
Soft Keys

provides additional functionality to the [SCAN] and/or [OK] and/or
[3CH] buttons during DSC operations.
