If you exceed these ascent rates, the IQ-600’s audible alarm
will sound, and the computer will display its Ascent Rate
Warning, as shown in Figure 10. This consists of the SLOW
symbol and current depth indicators blinking on and off. The
Ascent Rate Warning will continue to display until you slow
your ascent rate to that which the IQ-600 finds acceptable, or
until you reach a depth of 5 ft/1.5m.
Deco Stop Violation Warning—In so far as the IQ-600 is
not designed nor intended for planned decompression dives,
you should consider the very fact the computer indicates a
need for mandatory stops as a significant warning in itself.
Once you enter this mode, you should further be alert to the
possibility of a Deco Stop Violation warning.
A Deco Stop Violation takes place when you either
ascend shallower than the indicated stop depth or do not
spend sufficient time there before ascending. To warn you
of this violation, the computer’s audible alarm sounds, and
the stop depth and stop time, along with the DECO symbol,
blink on and off. These items will continue blinking as long
as you remain shallower than the indicated stop depth.
