Preamble Message Outro
Three long, rising, sharp telephone tones Achtung, Achtung 32587 32587 05458 05458 ... 32125 32125 Ende, Ende
Repeated for 5 minutes   5-figure paired groups  

No amount of 5-figure groups in the message was given. Up until 2000, transmitted messages were highly non-random, as it can be seen, for example, here. The messages didn't look as much non-random afterwards.

Historical schedule: First Thursday of the month at 20:05 and 20:35 UTC (summer) or 21:05 and 21:35 UTC (winter). The frequency of the first sending was random, but always within 3 - 6 MHz range, lower in European winter. The repeat was 100 kHz above the previous frequency (since 2000, lower before that).
