[. . . ] As with any tool, the Matrix may be misused if the following safety and operational precautions are not strictly followed. If they are followed, careful use of the Matrix can increase your diving enjoyment and reduce the risk of decompression sickness; if they are not followed, you will be placing yourself at serious risk for decompression sickness. Pay special attention to warnings and cautions, which are denoted by this symbol WARNINGS are used before a procedure or situation that may result in serious injury or death. CAUTIONS are used before any situation or technique that will result in damage to the product. [. . . ] Divers strongly recommends that you wait until the segments of the CLBG are well within the green zone before surfacing, unless a low air situation dictates that you surface. At the end of all decompression dives, spend as much time as possible at your safety stop and on the surface to reduce your compartment loading before the next dive. VIOLATION MODES The Matrix enters one of three different Violation Modes when you dive the computer beyond its normal operating limits, because continued exposure is outside the mathematical model used to calculate decompression status. These modes are explained in detail in the next chapter, “Extreme Situations. € GAUGE MODE If the Matrix enters a Permanent Violation Mode, it will only operate in Gauge Mode on subsequent dives. gauge Mode is explained in detail in the next chapter , “Extreme Situations. € DIVE LOG MODE Accessing the Dive Log Mode Ten minutes after surfacing from a dive, you can access the Dive Log Mode by pressing the neon-yellow button at any time. After entering the Dive Log, the Matrix scrolls through all dives in memory, beginning with the most recent dive. However, if you need to pause the dive log scrolling to write down the information in a logbook, press and hold the neon-yellow button anytime during the scroll to freeze the display. Note: If you hold the button down to enter Dive Log Mode, and do not release the button for eight seconds, the Matrix enters External Access Mode. In External Access, the Matrix displays the letters “EA” and counts down from 6 to 0. Your buddy would be unable to lend assistance without also risking decompression sickness. VIOLATION MODES If you exceed certain limits, the Matrix will not be able to tell you how to get back to the surface. These situations will make the Matrix enter Violation Mode and must be avoided at all costs. They push decompression theory to the limits and can result in loss of some Matrix functions for 24 hours after the last dive of the day in which a violation occurred. they are termed “Conditional Violation , ” “Delayed Violation Mode , ” and “Immediate Violation Mode. € It is important to understand how each of these modes function and how to carry out decompression procedures in the event you encounter one. Conditional Violation Mode Before a situation causes the loss of nitrogen monitoring functions, the Matrix enters Condition Violation Mode. If properly handled, the Conditional Violation Mode will not only assist you in getting back to the surface, but will also allow continued use of the computer. There is only one situation that forces the Matrix to enter a Conditional Violation Mode: Ascending above the required decompression stop. S Ascending Shallower than the Required Decompression Stop The Matrix will enter a Conditional Violation Mode if you ascend shallower than the indicated stop depth for less than five minutes. This can easily happen if you temporarily lose control of your buoyancy, or get caught in a surge or swell. [. . . ] Figure 17 Low Battery Display WARNING: All memory of tissue loading is erased when the batteries are removed. If you change batteries between dives, you must wait 24 hours before diving again. If you need to change the batteries yourself, follow these simple procedures: Removing the Matrix from the Console Boot 1. To avoid damage to the gauge, make sure to work over a soft, cushioned surface. [. . . ]
