3.14 Error state (algorithm lock)
Suunto DX has warning indicators that alert you to react to certain
situations that would significantly increase the risk of DCI. If you do
not respond to these warnings, Suunto DX enters an error state and
shows Er on the display. This indicates that the risk of DCI has
greatly increased.
If you omit decompression stops for longer than three (3) minutes,
the RGBM algorithm is locked for 48 hours. When the algorithm is
locked, no algorithm information is available and
ER
is shown
instead. Locking the algorithm is a safety feature, highlighting that
the algorithm information is no longer valid.
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 DX locks the algorithm calculation and displays
ER
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.
