MAKING A DISTRESS CALL

Lift the red cover. Press and hold the DISTRESS key for three seconds. Your radio transmits your ship’s location every few minutes until you receive a response.

NOTE:
If the radio displays Enter User MMSI, cancel the automatic distress call and make a normal voice distress call.

Making a Voice Distress Call

Speak slowly – clearly – calmly

For future reference, write your ship’s name & call sign here:

  1.  Make sure your radio is on.
  2.  Press the 16/P key to switch to Channel 16 (156.8 MHz). (If the corner of the display does not show 16, press the 16/P key again until it does.)
  3.  Press the PUSH-TO-TALK key and say: “MAYDAY — MAYDAY — MAYDAY.”
  4.  Say “THIS IS {name of your ship (three times)} and call sign/ship registration number (once).”
  5.  Repeat “MAYDAY {name of your ship}” once.
  6.  Tell where you are: (what navigational aids or landmarks are near, or read the latitude and longitude from your GPS).
  7.  State the nature of your distress (e.g. are you sinking, medical emergency, man overboard, on fire, adrift, etc. ).
  8.  State the type of assistance you need (medical, towing, pumps, etc.).
  9.  Give number of persons aboard and conditions of any injured persons.
  10.  Estimate present seaworthiness of your ship (e.g. how immediate is the danger due to flooding or fire or proximity to shore).
  11.  Briefly describe your ship, giving ship name (e.g. “Blue Duck is 32-foot cabin cruiser, white hull, blue deckhouse”).
  12.  Say: “I WILL BE LISTENING ON CHANNEL 16.”
  13.  End message by saying “THIS IS {name or call sign of your ship}, OVER.”
  14.  Release the PUSH-TO-TALK key and listen.

If you do not get an answer after 30 seconds, repeat your call, beginning at step 3, above.
