Algorithm Lock; Ascent Rate - Suunto D5 User Manual

Suunto D5
Vent.: ventilation time; this is the starting duration of the time your breathing time. The
•
time is increased by the increment time for each interval.
Incr: increment time; this is added to the ventilation time for each interval. For example, if
•
your ventilation time is 1:00 minute and your increment time is 0:30 seconds, the first
interval ventilation is 1:00, the second is 1:30, the third is 2:00, and so on.
Repeats: number of intervals

WARNING: Anyone who engages in any form of breath hold diving is in danger of
shallow-water blackout (SWB), the sudden loss of consciousness caused by oxygen
starvation.

3.3. Algorithm Lock

Suunto Fused™ RGBM algorithm is locked for 48 hours if you omit decompression stops for
longer than three (3) minutes. When the algorithm is locked, no algorithm information is
available and Locked is shown instead. Locking the algorithm is a safety feature, highlighting
that the algorithm information is no longer valid.
When you ascend above the decompression ceiling by more than 0.6 m (2 ft), the ceiling
parameter turns red with an arrow pointing down appears, and an audio alarm is generated.
In such a condition, you should descend back below the ceiling level to continue the
decompression. If you fail to do so within three (3) minutes, Suunto D5 locks the algorithm
calculation and displays Locked instead, as shown below. Note that the ceiling value is no
longer present.
In this state, you significantly increase your risk of decompression sickness (DCS).
Decompression information is not available for the next 48 hours after surfacing.
It is possible to dive with the device when the algorithm is locked, but instead of the
decompression information, Locked is shown. Diving while the algorithm is locked resets the
algorithm lock time back to 48 hours when you surface.

3.4. Ascent Rate

During a dive, the bar on the left indicates ascent rate. One bar step corresponds to 2 m (6.6
ft) per minute.
The bar is also color coded:
• Green indicates ascent rate is ok, less than 8 m (26.2 ft) per minute
