In such event, you should descend 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.
Algorithm locked
Suunto Fused™ RGBM 2 algorithm is locked for 48 hours if you omit to take 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highlighting that the algorithm information is no longer valid.
Algorithm locked in Timer view:
Algorithm locked in No Deco view:
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.
3.3. 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
•
Yellow indicates ascent rate is moderately high, 8-10 m (26-33 ft) per minute
•
Red indicates ascent rate is too high, over 10 m (33 ft) per minute
