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 V90 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 V90 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.
Softkeys
A softkey is a name that appears at the bottom of the screen and
provides additional functionality to the [SCAN] and/or [OK] and/or
[3CH] buttons during DSC operations.
Dot symbols on the handset keys and just under the display screen
indicate which keys correspond to the softkeys as follows:
• • • • • •
[SCAN] key [OK] key [3CH] key
The following table shows the softkeys that occur in DSC mode.
