Sec. 80.312  Priority of distress transmissions.

    The distress call has absolute priority over all other 
transmissions. All stations which hear it must immediately cease any 
transmission capable of interfering with the distress traffic and must 
continue to listen on the frequency used for the emission of the 
distress call. This call must not be addressed to a particular station. 
Acknowledgement of receipt must not be given before the distress message 
which follows it is sent.
