Certain models of Digital Selective Calling-equipped VHF radios will automatically switch from a working channel to Channel 16 upon receipt of a DSC distress alert, distress alert acknowledgment and other DSC calls in which a channel number has been designated, according to a Coast Guard Safety Alert.

A navigation safety hazard may consequently occur if the radio is being used to maintain a listening watch or to communicate on the designated bridge-to-bridge radiotelephone or vessel traffic services monitoring channel.
