6. When you are between 2.4 and 6 m (7.9 and 20 ft), a safety stop timer will appear and
count down until the suggested stop. Once the stop is performed, a Stop done
notification

5.8.5. Example - Multigas mode
The following example shows a decompression dive to 40 m in Multigas mode and with the
following gases: NX28 (main gas), NX99 decompression gas.
1. Pre dive screen – showing the active gas (NX28), set ppO2 and MOD.
2. NDL alarm at 5 min.
3. NDL reaches 0 and decompression is needed. The gauge changes to orange indicating
Deco time. The NDL area shows the TTS value including deco stops and safety stop. The
ceiling value is displayed in the switch window.
4. The ceiling value is 9 m so you can ascend to this depth within the ascent speed limits.
Once arriving close to the ceiling depth and entering the decompression window area,
two arrows appear next to the depth number and a timer appears in the Deco field
indicating a deco stop of 1 min. Once the countdown is 0, the TTS value is displayed again
and the ceiling value has changed 3 m shallower, to 6 m.
