Always dive within the limits of your training skills and experience Technical diving activities including decompression diving mixed gas diving rebreather diving wreck and cave diving all substantially increase the risks of scuba diving The KAON dive computer is capable of calculating decompression requirements based on the B hlmann ZH L16C algorithm first published in 19901 Decompression is an inexact science It is possible to follow a decompression plan exactly and still suffer decompression sickness Following a decompression plan does not in any way guarantee the avoidance of decompression sickness The same profile that gets you out of the water safely one day may cause decompression sickness another day and lead fo temporary or permanent injury or death You can die while diving WARNING ELECTRONICS CAN FAIL ALWAYS CARRY BACKUP he KAON dive computer hardware like any electronic equipment whose components mature and age If they fail during your dive they can stop providing you with critical information You must have a plan to handle the failure of the KAON dive computer during your dive You should carry backup instruments including a depth gauge submersible pressure gauge digital bottom timer or dive watch a compass and have access to decompression tables Do not risk your life on only one source of information WARNING ALWAYS CHECK FOR SOFTWARE UPDATES The KAON dive computer software likely still has b2. assuming that you follow the dive plan precisely You can configure two types of waypoints Normal where you set a target Depth and a Time spent at that depth and your KAON uses this information to create a dive plan Switch where you set a target Depth and a Gas you want to switch to at that depth and your KAON uses this information to create a dive plan 3 5 Alarms Your KAON can display visual alarms when you exceed any of the following parameters e Maximum depth e Maximum dive time e Maximum ascent rate e Maximum descent rate When the alarm is activated for any parameter that piece of information will start blinking on your screen for one minute If you do not correct the situation within one minute the parameter display will invert i e it will appear as black letters on colored background until you correct situation causing the alarm Once you do that the alarm will turn off The only exception is a time alarm It will blink for I minute after which it will go back to normal 3 6 Your Saturation only in Rec amp Tec modes This menu item displays a screen with your current saturation calculated with the BUhImann ZH L16C algorithm The information presented here takes into account data from dives you have actually completed Liquivision Products Inc 12 KAON Manual Liquivision KAON Dive Computer User Manual Your Saturation screen after a period of no Your Saturation screen after a deep dive diving
