5. DIVE COMPUTER LIMITS DOES CARRY SOME RISK OF DECOMPRESSION SICKNESS COMPARTMENTS AND HALF TIMES When you dive with the instrument it measures and displays depths and times as your dive progresses It shows you available no decompression time and possible decompression required based upon the following five factors 1 your present depth 2 excess nitrogen absorbed during earlier portions of the dive 3 residual nitrogen remaining from previous dives 4 the no decompression limits that apply to that depth 5 the personal altitude adjustment mode in use Back on the surface the dive computer will continue to calculate the no decompression dive times available for various depths on the next dive As the surface interval increases so does the available dive time for the next dive 57 To perform these calculations the dive computer continuously models the absorption and release of excess nitrogen from theoretical compartments Each compartment absorbs and releases nitrogen at a different rate The compartments that absorb and release nitrogen rapidly are believed to have a high tolerance for excess nitrogen whereas compartments that absorb and release nitrogen more slowly are believed to be more sensitive The no decompression limits in the U S Navy tables are based upon six theoretical compartments for single dives and one compartment for surface intervals and repetitive dives If you are familiar with table theory you may know tha

14. L ALTITUDE ADJUSTMENT MODE When diving at altitudes greater than 700 m 2300 ft the personal altitude adjustment feature must be correctly selected in order for the computer to calculate no decompression status The diver should also use this option to make the calculation more conservative whenever it is believed that factors which tend to increase the possibility of decompression sickness exist see Section 3 5 Failure to properly select the personal altitude adjustment mode correctly will result in erroneous data and can greatly increase the risk of decompression sickness WARNING THE INSTRUMENT IS NOT INTENDED FOR USE AT ALTITUDES GREATER THAN 2400 m 8000 ft Diving at altitudes above this limit may significantly increase the risk of decompression sickness When diving at higher altitudes above 700 m 2300 ft it is essential that the entered altitude mode i e maximum altitude limit of the dive computer exceeds or is equal to the altitude of the dive site The altitude mode indicator must show either Al or A2 depending on the altitude More information about this is given in Section 3 5 Personal Adjustment and High Altitude Dives DECOMPRESSION DIVES WARNING DO NOT USE THIS INSTRUMENT TO CONDUCT DECOMPRESSION DIVES Suunto does not recommend this instrument to be used to conduct decompression dives However if through carelessness or emergency a diver is forced to exceed the no decompression limits on a dive the instru

53. to reduce the probability of decompression sickness The mathematical model uses an ascent rate of 10 m min 33 ft min Therefore it is critical that a proper ascent rate is always used The reader diver is forewarned that individual physiological differences severe environmental conditions and predive activities especially those which tend to increase dehydration may increase the risk of decompression sickness As a safety precaution Suunto recommends that divers using this instrument should maintain no less than 10 minutes no decompression time remaining at all times during the dive This is especially important for divers in poor physical condition in cold water or other strenuous conditions Historically divers have been advised to always include a margin of safety in their diving activities Suunto supports these practices and strongly recommends that the diver make the deepest portion of the dive near the beginning of the dive and gradually progress into shallower depth allowing time for a 3 to 5 minutes safety stop at a depth range of 3 to 6 meters 10 to 20 ft This is believed to be effective in further reducing the risk of decompression sickness Furthermore the reader diver is advised that any dive carries some risk of decompression sickness and neither the authors nor SUUNTO Oy will assume any responsibility or liability for accidents or injuries which might occur for any reason 16 2 GETTING ACQUAINTED WITH THE DIVE C
