All menu based modes can be deactivated by the RETURN command, i.e. by
connecting all three contacts simultaneously, or by immersing the
IQ-400
in
water.
4.1 Logbook Memory
The
IQ-400
has a sophisticated high capacity
Logbook Memory. Dives shorter than one minute
are not registered.
The logbook memory is activated by touching the
MODE and MODE/PLAN contacts until LOG
appears. It will give access to the nine most recent
dives made.
The following information will be shown on three
alternating displays (Fig. 4.2 - 4.5):
Display I, Main Display (Fig. 4.2):
• maximum depth (a)
• dive number (c)
• dive time (e)
• personal/ altitude adjustment setting (d)
• the minimum NO DEC TIME or maximum
ASC TIME reached during the dive (b)
• SLOW if the diver has surfaced with this
warning on
• downward pointing arrow if the ceiling was violated
• Er in the center window, if the ceiling was violated permanently (over 3 min)
or if the 12 m [39 ft] ceiling was reached or if the ASC TIME was over 63 min.
DISPLAY II (Fig. 4.3):
• average depth (a)
• surface interval time before dive (b)
• temperature at the maximum depth (c)
• dive time
29
NOTE
The menu based modes can be activated only when 10 minutes
have elapsed after the dive.
