[. . . ] MATRIX MANUAL Safety Considerations You must carefully read this entire manual before using your Matrix. wARNING: Diving has many inherent risks. Decompression sickness is among the most serious of those risks. Even if you follow the instructions in this manual carefully, it is possible that you may be seriously injured or die from decompression sickness, or some other inherent risk of SCUBA diving. [. . . ] In External Access, the Matrix displays the letters “EA” and counts down from 6 to 0. Figure 11 Dive Log Mode Memory Capacity The Matrix retains the information for the last 10 dives indefinitely, even if you remove the batteries. After exceeding the 10 dive limit, the newest dive is added to memory while the oldest dive is deleted. Dive Log Display When you enter Dive Log Mode (figure 11), the Matrix displays the logbook Icon (a) with the dive number (b) immediately to the right. Maximum depth (c) and total bottom time (d) are located at the bottom of the screen. The Compartment Loading Bar Graph (e) shows the nitrogen loading level at the end of the dive. The ascent rate indicator (f) shows the fastest ascent rate during the dive. Lastly, if a decompression stop was required during the dive, the "DECO" label (g) is displayed. Extreme Situations EXCEEDING THE MAXIMUM DEPTH The Matrix displays the current depth down to 250 feet (76 m). (76 m), the current depth and maximum depth will display three dashes (figure 12), indicating that the Matrix is beyond its depth range. (76 m), the current depth display returns to normal, while the maximum depth continues to show three dashes. Note: If you exceed the 250 foot (76 m) limit, three dashes will be displayed as the maximum depth when you view the dive in Dive Log Mode. Although the Matrix withstands the pressure at 250 ft. (76 m), the depth at which you can use all its features can be much shallower. Before going further, read the following warning: WARNING: The maximum recommended sport diving limit is 130 feet (40 m). Diving any deeper than 130 feet (40m) should be avoided. Special equipment and training are necessary for this type of diving. Divers strongly recommends against diving to depths below 130 ft. Figure 12 Exceeding the Maximum Depth EMERGENCY DECOMPRESSION After entering decompression, the prescribed decompression stop depths may move quickly through the 10, 20, 30 and 40 foot (3, 6, 9, 12 m) displays. Once you enter decompression, it is imperative that you ascend toward the required stop depth immediately. If you continue the dive at a greater depth, you increase decompression risk and may also exceed the operating limits of the computer to such an extent that the computer will cease to provide ascent information. WARNING: If the Matrix display indicates you have entered decompression mode, do not descend further or remain at the same depth. [. . . ] Run your finger around the outer edge of the top battery in a circular motion until one edge of the battery pops up. Turn the unit over so the bottom battery drops out into your hand. Discard the used batteries, regardless of age or amount of use. Closely examine the metal contacts inside the battery compartment; check for signs of bending, breakage or corrosion, which indicates the entrance of moisture into the battery compartment. [. . . ]
