[. . . ] You should always make the Mandatory and Recommended Safety Stops after you have exceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompression model will penalize your next dive(s). Continuous ascent rate violations will result in Mandatory Safety Stops. When Recommended Deep Stop is enabled, the length is indicated in seconds. 6. 1. 5. Safety Stops A 3 minute Recommended Safety Stop is prompted after every dive to over 10m. Decompression dives When your NO DEC TIME becomes zero, your dive becomes a decompression dive so you must perform one or more decompression stops on your way to the surface. The NO DEC TIME on your display will be replaced by an ASC TIME, and a CEILING notation will appear. An upward pointing arrow will also prompt you to start your ascent. If you exceed the no-decompression limits on a dive, the dive computer will provide the decompression information required for ascent. After this, the instrument will continue to provide subsequent interval and repetitive dive information. Rather than requiring you to make stops at fixed depths, the dive computer lets you decompress within a range of depths (continuous decompression). 30 UPWARD POINTING ARROW, BLINKING ASC TIME AND AN ALARM TELL YOU TO ASCEND. MINIMUM TOTAL ASCENT TIME INCLUDING MANDATORY SAFETY STOP IS 15 MINUTES. CEILING IS AT 3 M. Display above the floor When you ascend above the floor, the ASC TIME display stops blinking and the upward pointing arrow disappears. Below is an example of a decompression dive above the floor. UPWARD POINTING ARROW HAS DISAPPEARED AND ASC TIME LABEL HAS STOPPED BLINKING, MEANING YOU ARE IN THE DECOMPRESSION RANGE. Decompression will now begin, but is very slow. You should therefore continue your ascent. Display at the ceiling zone When you reach the ceiling zone, the display will show you two arrows pointing at each other (the "hour glass" icon). Below is an example of a decompression dive at the ceiling zone. TWO ARROWS POINT AT EACH OTHER "HOUR GLASS" YOU ARE IN THE OPTIMUM CEILING . AND YOUR MINIMUM ASCENT TIME IS 15 MINUTES. During the decompression stop, ASC TIME will count down towards zero. When the ceiling moves upwards, you can ascend to the new ceiling. You may surface only after the ASC TIME and CEILING labels have disappeared, which means that the decompression stop and any Mandatory Safety Stop have been completed. You are advised, however, to stay until the STOP sign has also disappeared. [. . . ] Abbreviation for no decompression time limit. Abbreviations for oxygen enriched air nitrox. Used to measure the whole-body-toxicity. A term used by Suunto for the values displayed in the oxygen toxicity bar graph. [. . . ]
