It has been brought to our notice that the call "C.Q." (All Stations), while being satisfactory for general purposes, does not sufficiently express the urgency required in a signal of distress.
Therefore, on and after the 1st February, 1904, the call to be given by ships in distress or in any way requiring assistance shall be "C.Q.D."
This signal must on no account be used except by order of the Captain of the ship in distress, or other vessels or stations retransmitting the signal on account of the ship in distress.
All stations must recognise the urgency of this call and make every effort to establish satisfactory communication with the least possible delay.
Any mis-use of the call will result in the instant dismissal of the person improperly employing it.
