5. COMPUTER TO CHECK THE REMAINING NO FLY TIME PRIOR TO FLYING Flying or traveling to a higher altitude within the no fly time can greatly increase the risk of DCS Review the recommendations given by Divers Alert Network DAN There can never be a flying after diving rule that is guaranteed to completely prevent decompression sickness WARNING THE DIVE COMPUTER SHOULD NEVER BE TRADED OR SHARED BETWEEN USERS WHILE IT IS IN OPERATION Its information will not apply to someone who has not been wearing it throughout a dive or sequence of repetitive dives It dive profiles must match that of the user If it is left on the surface during any dive the dive computer will give inaccurate information for subsequent dives No dive computer can take into account dives made without the computer Thus any diving activity up to four days prior to initial use of the computer may cause misleading information and must be avoided WARNING DO NOT EXPOSE ANY PART OF YOUR DIVE COMPUTER TO ANY GAS MIX CONTAINING MORE THAN 40 OXYGEN Enriched air with greater oxygen content presents a risk of fire or explosion and serious injury or death WARNING THE DIVE COMPUTER WILL NOT ACCEPT FRACTIONAL PERCENTAGE VALUES OF OXYGEN CONCENTRATION DO NOT ROUND UP FRACTIONAL PERCENTAGES For example 31 8 oxygen should be entered as 31 Rounding up will cause nitrogen percentages to be understated and will affect decompression calculations If there is a desire to adjust the
