Recommended Safety Stops With every dive over 10 meters, there is a three-minute countdown for the Recommen- ded Safety Stop, to be taken in the 3–6 m/10–20 ft range.
  • Page 52 (5) seconds, the microbubble build-up is predicted to be more than is allowed for in the decompression model. The Suunto RGBM calculation model responds to this by adding a Mandatory Safety Stop to the dive. The time of this Mandatory Safety Stop depends on the severity of the ascent rate excess.
  • Page 53 You must not ascend shallower than 3 m/10 ft with the Mandatory Safety Stop warning on. If you ascend above the Mandatory Safety Stop ceiling, a downward pointing arrow will appear and a continuous beeping starts. You should immediately descend to, or below, the Mandatory Safety Stop ceiling depth.
  • Page 54 6. DIVING This section contains instructions on how to operate the dive computer and interpret its displays. The dive computer is easy to use and read. Each display shows only the data relevant to that specific diving mode. 6.1. Diving in AIR mode This section contains information on diving with standard air.
  • Page 55 The dive computer will remain in the SURFACE mode at depths NOTE less than 1.2 m/4 ft. At depths greater than 1.2 m/4 ft the instru- ment will go into the DIVE mode automatically. However, it is re- commended that you activate the SURFACE mode manually before entering the water in order to perform the necessary dive pre-checks.
  • Page 56 Bookmarks will be shown as a dive log symbol when scrolling the profi le memory on the computer display. The Bookmarks will also be shown as annotations in the PC- software, Suunto Dive Manager. To make a bookmark on the profile memory during a dive press the PLAN button.
  • Page 57 200 minutes, the first (lowest) bar graph segment appears. As your body absorbs more nitrogen, more segments start to appear. Green Zone– As a safety precaution Suunto recommends you should maintain the no-decompression bar graph within the green zone. Segments start to appear when the available no-decompression time decreases below 100, 80, 60, 50, 40, 30, and 20 minutes.
  • Page 58 Red Zone– As all of the bars appear (red zone), your no-decompression stop time has become zero and your dive has become a decompression stop dive (for more information see Section 6.1.5. Decompression dives). 6.1.4. Ascent rate indicator The ascent rate is displayed graphically along the right hand side with a vertical bar. When the maximum allowed ascent rate is exceeded, the fifth SLOW warning segment and the STOP sign appear and the depth reading starts to blink, indicating that the maximum ascent rate has been exceeded continuously or that the current ascent rate...
  • Page 59 When the maximum allowed ascent rate is exceeded the fifth SLOW warning segment and the STOP sign appear and the depth reading starts to blink indicating that the maximum ascent rate has been exceeded continuously or that the ascent rate is above the allowed maximum rate.
  • Page 60 DO NOT EXCEED THE MAXIMUM ASCENT RATE! Rapid as- WARNING cents increase the risk of injury. You should always make the Mandatory and Recommended Safety Stops after you have ex- ceeded the maximum recommended ascent rate. If this Mandatory Safety Stop is not completed, the decompression model will penalize your next dive(s).
  • Page 61 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).
  • Page 62 Ceiling, ceiling zone, floor and decompression range When in decompression, it is important that you understand the meaning of ceiling, floor, and decompression range. The ceiling is the shallowest depth to which you should ascend when in decom- • pression. At this depth, or below, you must perform all stops. The ceiling zone is the optimum decompression stop zone.
  • Page 63 In such cases, it is more manageable to maintain an additional distance below the ceiling, to ensure that the waves do not lift you above the ceiling. Suunto recom- mends that decompression takes place deeper than 4 m/13 ft, even if the indicated ceiling is shallower.
  • Page 64 Figure 6.7. Decompression dive, below floor. Upward pointing arrow, blinking ASC TIME label and an audible alarm tell you to ascend. Minimum total ascent time including safety stop is 7 minutes. Ceiling is at 3 m/10 ft. Display above the floor When you ascend above the floor, the ASC TIME sign stops blinking and the upward pointing arrow disappears.
  • Page 65 Figure 6.8. Decompression dive, above the floor. The upward pointing arrow has disappeared and the ASC TIME label has stopped blinking, which means that you are in the decompression range. Decompression will now begin, but is very slow. Therefore, you should continue your ascent.

You are in the optimum ceiling zone at 3.5 m/11 ft and your minimum ascent time is 5 minutes. Pressing TIME button activates alternative display. During the decompression stop, ASC TIME will count down towards zero.
  • Page 67 Figure 6.10. Decompression dive, above ceiling. Note a downward pointing arrow, an Er warning and an audible alarm. You should immediately (within 3 minutes) descend to or below ceiling. In addition, an Error warning (Er) reminds you that you have only three (3) minutes to correct the situation.
  • Page 68 6.2.1. Before diving in the NITROX mode If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder must always be entered into the computer to ensure correct nitrogen and oxygen calculations.

Altitude diving The atmospheric pressure is lower at high altitudes than at sea level. After traveling to a higher altitude, you will have additional nitrogen in your body, compared to the equilibrium situation at the original altitude.
  • Page 110 Before high-altitude diving, the instrument must be set to the Altitude Adjustment mode to adjust the calculations for the new altitude. The maximum partial pressures of nitro- gen allowed by the mathematical model of the dive computer are reduced according to the lower ambient pressure.
