Algorithm Lock - Suunto EON STEEL 1.4 User Manual

NOTE: Gas time reading shows zero and turns red if tank
pressure goes below 35 bar (500 psi).

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highlighting that the algorithm information is no longer valid.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 EON Steel locks the algorithm calculation and
displays LOCKED instead, as shown below. Note that the ceiling
value is no longer present.
