After having transmitted the DSC distress alert on appropriate DSC distress channels (HF, MF and/or VHF), prepare for the subsequent distress traffic by tuning the radiocommunication set(s) (HF, MF and/or VHF as appropriate) to the corresponding distress traffic channel(s). If method b) described above has been used for transmission of DSC distress alert on a number of HF bands: take into account in which HF band(s) acknowledgment has been successfully received from a coast station; if acknowledgments have been received on more than one HF band, commence the transmission of distress traffic on one of bands, but if no response is received from a coast station then the other bands should be used in turn. The distress traffic frequencies are: HF (kHz): Telephony 4125 6215 8291 12290 16420 Telex 4177.5 6268 8376.5 12520 16695 MF (kHz): Telephony 2182 2174.5 VHF: Channel 16 (156.800 MHZ). Distress traffic The procedures described earlier are used when the distress traffic on MF/HF is carried out by radiotelephony. The following procedures shall be used in cases where" the distress traffic on MF/HF is carried out by radiotelex: The forward error correcting (FEC) mode shall be used unless specifically requested to do otherwise; all messages shall be preceded by: at least one carriage return, line feed, one letter the distress signal "MAYDAY"; The ship in distress should commence the distress telex traffic on the appropriate distress telex traffic channel as follows: carriage return, line feed, letter shift, the distress signal "MAYDAY",
