yet in distress).

Making an automatic distress call
If you have programmed your MMSI number, your radio can transmit an automated distress
call with your current location and nature of the distress. The radio then monitors the
channel 16 for a response and repeats the distress call every few minutes until it receives an
acknowledgement.
To send an automatic distress call, press and hold DISTRESS for three seconds. If
no MMSI number has been programmed, the radio prompts you to enter your MMSI
number.
If you want to include the nature of your distress in the distress call, use the following
distress procedure:
1. Press DISTRESS .
2. The radio displays the list of distress conditions; use CHANNEL UP and CHANNEL DOWN to
choose the nature of your distress, then press and hold DISTRESS for three seconds.
