• 1 Introduction 1.1 Glossary Symbolizes dive violation (in dive mode). : : Symbolizes uncontrolled ascent violation (in post-dive and logbook displays). : Symbolizes decompression stop violation (in post-dive and logbook displays). ASC: Total ascent time, the time it takes to perform the ascent from your current depth to the surface in a decompression dive, including all decompression stops and assuming an ascent rate of 10m/min or 33ft/min.
MATRIX Dive Computer 1.2 OPERATINg MOdES The functions of the Matrix computer can be grouped into two categories, each corresponding to a specific mode of operation: • watch : Matrix is dry on the surface. In this mode you can use it as a normal watch.
1.4 BuTTON OPERATION Matrix has four buttons. These buttons allow you to access menus and change settings while in surface mode. During the dive they switch displays, call up the compass, and allow to display further information on the computer screen. Each button performs a different function when it is pressed and when it is pressed and held for one second.

The number shown in the middle of the compass rose represents the bearing, between 0 (North) and 359. 1.4.1 DIGITAL WATCH DISPLAY The digital watch display is the “home” display of Matrix. In this mode, you have a central ribbon with the current time in hours and minutes, while the top and bottom portions of the display can be customized. 1.4.3.1 SETTING A BEARING 1.4.2 ANALOG WATCH DISPLAY From the digital watch display, press the top left button to switch to a simulated analog watch display.
MATRIX Dive Computer • 2 Menus, settings and functions This chapter describes in detail all menus, setting and functions of the Matrix dive computer. Press and hold the top right button to reach the main menu. Inside this you will see the following submenus: Note - If you remain in pre-dive for longer than 10 minutes without pressing any button, Matrix will return to the time of day display. - It is recommended to put Matrix into pre-dive before submerging.
Press and hold the top right button to enter a menu or submenu, press the right side buttons to scroll up and down between available options or to increase or decrease the value of a setting. Then press and hold the top right button to confirm the change in setting. Press or press and hold the top left button to exit a menu without saving the last change. MENU Description SET DIVE backlight Allows you to set the duration after which the backlight turns off automatically.
MATRIX Dive Computer locking up of the computer in the event of an uncontrolled ascent. WARNING - An uncontrolled ascent increases your risk of decompression sickness (DCS) - This feature is intended for very experienced divers only, such as dive instructors, who take full responsibility for the consequences of turning off this function. 2.2.1.7 Alarms In this menu you can disable audible alarms.
diver’s body at the same depth as compared to breathing air. 2.4 DIVE PLANNER This function allows you to scroll through the no decompression limits, automatically taking into account the current residual saturation of the tissue compartments from a preceding dive.
MATRIX Dive Computer Oxygen toxicity exposure is tracked on Matrix by means of the CNS % based on currently accepted recommendations for exposure limits. This toxicity is expressed as a percentage value which ranges from 0% to 100%. When the value reaches 75%, an alarm goes off and the message CNS > 75% appears for 10 seconds.
3.2.5 Low battery WARNING Do not start a dive if the low battery warning is displayed on the screen on the surface. The computer may fail to function during the dive and this could lead to serious injury or death. If Matrix detects that the battery power level is getting below 10%, it will show the message LOW BATTERY on the display. In a LOW BATTERY situation, the backlight is disabled, as well as audible signals. WARNING When this warning appears, you should stop the dive, safely, without delay.
MATRIX Dive Computer During a decompression stop, the following symbols may appear: : optimal range for the decompression stop; : above decompression stop depth, descend immediately! The nitrogen bar graph is on the left side of the display. It represents nitrogen saturation in the leading tissue compartment. The bar graph is made of six segments, which gradually fill during the dive. The more black segments you see, the closer to the no deco limits you are.
- The surface interval (SURF): this is displayed from the moment the dive is closed (3 minutes after surfacing) for as long as there is remaining desaturation or no-fly time on the computer. - In case of a dive violation, the corresponding 3.3.1.3 STOP SUMMARY TABLE The stop summary table lists each individual stop in depth and duration, including safety, deco and deep stops. This table does not appear as long as you are in a no deco dive without deep stop requirement. symbol ( , interval.
MATRIX Dive Computer Note - If you dive using just one gas, select G1 and deselect the other two. - For dives with two gases, select G1 and G2 and deselect the third. - When enabling G2 and G3, you must first define G2 and then G3. - You cannot activate G3 without first having activated G2. - G2 cannot have an oxygen percentage higher than G3. - If you set G2 to OFF, G3 will automatically be set to OFF also. - The MOD for G2 and G3 is the switch depth for the corresponding gas.
During a dive in bottom timer mode, the following information is displayed: • 4 TAKING CARE OF MATRIX 4.1 Technical information Operating altitude: - with decompression – sea level to approximately 3700m/12100ft - without decompression (gauge mode) – at any altitude Decompression model: RGBM Mares-Wienke (10 tissues) - current depth stopwatch dive time temperature in case of an ascent: ascent speed (in m/min or ft/min). Pressing and holding the bottom right button resets and restart the stopwatch.
