  • Page 3: Guidelines For The Use Of Aladin 2G

    • If Aladin 2G fails at any time during the dive, the dive must be terminated, and appropriate surfacing procedures (including a slow ascent and a 3 to 5 minute safety stop at 5 metres /15 feet) should be initiated immediately.
  • Page 4 • After diving, wait at least 24 hours prior to flying. Aladin 2G dive instrument is a personal protective equipment in compliance with the essential safety requirements of the European Union directive 89/686/EEC. RINA SpA, Via Corsica 12, I-16128 Genoa, notified body no. 0474, have certified the conformity with the European Standard EN 13319:2000.
