Smart dive computers
Smart Z draws the diver’s attention to certain situations and warns the diver of unsafe diving practices.
Attention messages and alarms are always visual and audible under water, only visual at the surface except
the decompression alarm.
The audible attention messages (but not the alarms) can be selectively
switched off with SmartTRAK.

2.1 Attention messages
Attention messages are communicated to the

res. In addition, two short audible sequences can
be heard (in an interval of 4 seconds) in two diffe-
rent frequencies under water.
Attention messages come up in the following
situations (more information can be found on the
listed pages):

2.2 Alarms
Serious injury or death may result from failing to
immediately respond to alarms given by Smart Z.
Alarms are given to the diver visually by flashing
symbols, letters or figures. In addition, an audible
sequence in one frequency can be heard during
the whole duration of the alarm.
An alarm occurs in the following situations (more
information can be found on the listed pages):
Page
• Oxygen toxicity reaches 100%
21
• Ignored decompression
23
• Remaining Bottom Time = 0
22
• Exceeding the prescribed ascent rate

(Particular scale of beeps, ->20)
• Low battery alarm*
