4.1 Dive time
The whole time spent below a depth of 4 feet is displayed as dive time in minu-
tes. While the dive time is running, the colon on the right of the figures is flas-
hing in one second intervals. Maximum dive time displayed is 199 minutes.
If a dive lasts longer than 199 minutes the dive time display starts
again at 0 minutes.
4.2 Current depth
Current depth is given in 1 foot-increments. On switching on and at
a diving depth of less than 2 ft the void display <—> appears.
Depth measurement is based on freshwater. Therefore,
Aladin
®
Pro Ultra shows a slightly greater depth than
actually true when diving in salt water, depending on
the salinity of the water.
4.3 Maximum depth
Maximum depth is displayed if it is lower than the current depth (maximum
indicator function). To prevent the display changing very frequently when
diving in the vicinity of maximum depth, it is only displayed if it exceeds the cur-
rent depth by more than three feet.
The portion of oxygen is displayed instead of maximum depth until a first
maximum depth is reached (but at least for the first 5 minutes of the dive).
