+==== Computer-reported events during dive
+Many dive computers record events during a dive. For instance,
+most dive computers report alarms relating to high partial pressures of oxygen,
+to rapid ascents or the exceeding of no-deco limits (NDL).
+On the other hand, other events are classified as warnings and, for instance, occur when
+the remaining gas in a cylinder falls below a predetermined limit, a deep stop needs to be performed or
+the need to change gas during multicylinder dives. Some dive computers also report notifications,
+e.g. when a safety stop is initiated or terminated or when a predetermined amount of OTUs have been incurred.
+The alarms, warnings and notifications differs from one dive computer to another: some dive computers do not
+report any of the above events, while others provide an extensive log of events. The reporting of events
+is therefore a function of the dive computer used. In addition, _Subsurface_ does not always
+have the ability to detect all the events reported by a specific dive computer.
+
+Events are indicated by symbols on the dive profile. Notifications are shown as a white, round symbol with a letter _i_;
+warnings are indicated by a yellow triangle and alarms by a red triangle. By moving the cursor over a symbol,
+the explanation is given in the bottom-most line of the _Information Box_ (see image below, where the cursor is positioned
+over the alarm that was reported).
