Suunto EON Steel Black User Guide 3.0

Ceiling broken

Algorithm lock

This section describes what happens if you break the decompression ceiling when diving with Suunto Fused™ RGBM 2 algorithm.

Breaking the decompression ceiling

When you ascend above the ceiling by more than 0.6 m (2 ft), the ceiling parameter turns red, a red, down pointing arrow appears, and an audio alarm is generated.

ErrorCond ceiling broken black

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 EON Steel Black 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.

Algorithm locked

Locking the algorithm is a safety feature, highlighting that the algorithm information is no longer valid.

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.

NOTE:

When you dive with Bühlmann 16 GF algorithm, the algorithm will not be locked even if you break the decompression ceiling and omit the decompression stops. See Warning: Ceiling broken for more information.

Warning: Ceiling broken

This section describes what happens if you break the decompression ceiling when diving with Bühlmann 16 GF algorithm.

Bühlmann 16 GF algorithm does not have the same algorithm lock as the one in Suunto Fused™ RGBM 2 algorithm. If you dive with Bühlmann 16 GF algorithm, your device will continue showing the original dive plan even if the decompression stop is violated. Approve the Ceiling broken warning by pushing the middle button.

When the warning disappears, Ceiling broken sign becomes visible on the left side of the screen.

Logs

If ceiling is broken during your dive, it will be visible in your dive logs. When you check the dive in numeric view, Ceiling broken is shown as a header of the log.

If you dive again after ceiling was broken, the new dive log has the header Ceiling broken in previous dive.

Dive planner

If ceiling is broken during your dive, it will be visible in the Dive planner. A pop-up message appears on the screen, saying Prior Ceiling Broken violation will affect planner accuracy. The message disappears after three seconds or it can be removed by pushing the middle button. After the message disappears, the planner can be used as usual.
