Distress calls
Distress calls are meant for situations where someone or a vessel is in immediate danger or in need of help. For example, if the vessel starts taking on water, or there is a fire, and the situation has gotten out of control.
The fastest way to make distress call is by lifting the flap and pressing the DISTRESS button located on the front of the X100. You can also make distress calls by using the DSC call softkey found on the AIS List and AIS Plot screens.
Once a distress call is sent, it automatically repeats every four minutes until it is acknowledged by a nearby vessel or coast station. This ensures that your emergency signal continues to broadcast, increasing the likelihood that help will receive your call quickly.
