• 1 Introduction 1.1 Glossary Symbolizes uncontrolled ascent violation. : Symbolizes decompression stop violation. : 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. AVG: Average depth, calculated from the beginning of the dive. CNS: Central Nervous System. CNS% is used to quantify toxic effects of oxygen. DESAT: Desaturation time.
Nemo Wide Dive Computer 1.2 OPERATING MODES 1.3 USER-REPLACEABLE battery The functions of the Nemo Wide computer can be grouped into three categories, each corresponding to a specific mode of operation: Nemo Wide uses a CR2450 user-replaceable battery. See section 4.2.1 for instructions on how to replace it. Good quality batteries should suffice for approx 300-500 dives, depending on the usage of the backlight and the temperature of the water.
SURFACE MODE press press and hold: BACKLIGHT (always with exception when G2 = ON and 02% on display) DIVE MODE press press and hold: BACKLIGHT (always with exception when G2 = ON and 02% on display) NITROX ONLY NITROX ONLY TIMEOUT 4” 5
Nemo Wide Dive Computer • 2 Menus, settings and functions 2.1 MOdE This chapter describes in detail all menus, setting and functions of the Nemo Wide dive computer. Nemo Wide always switches on in pre-dive mode.
2.2 SEt MENU Description SEt dIVE Nemo Wide’s SEt menu allows you to change settings. Once inside this menu, press the button to scroll between two submenus: or SEt dIVE, where you can set parameters pertaining to the dive, and SEt tIME, where you can set parameters pertaining to time and date. Press the enter button to enter a menu, press the or button to scroll up and down between available options or to increase or decrease the value of a setting.
Nemo Wide Dive Computer 2.2.1.3 ALt (ALTITUDE) 2.2.1.5 UN:tS (UNITS) 2.2.1.8 ErASE (ERASE DESATURATION) Atmospheric pressure is a function of altitude and of weather conditions. This is an important aspect to consider for diving, because the atmospheric pressure surrounding you has an influence on uptake and subsequent release of nitrogen. Above a certain altitude, the decompression algorithm has to change in order to account for the effect of the change in atmospheric pressure.
Press the or button to scroll between the pages of information, press the esc button to return to the list of the main logbook menu. 2.4 DIVE PLANNER This submenu allows you to download your dive data to a PC or Mac. Press the enter button and the display will show PC ready, symbolizing that Nemo Wide is ready to communicate. 2.6 INFO 2.3 LOGBOOK Nemo Wide can record the profiles of approximately 35 hours of diving, at a sampling rate of 5 seconds.
Nemo Wide Dive Computer as it is set to either air or nitrox): • Against sudden effects: Nemo Wide has an MOD alarm set for a user-defined ppO2max. As you enter the oxygen concentration for the dive, Nemo Wide shows you the corresponding MOD for the defined ppO2max. The default value of ppO2max from the factory is 1.4bar. This can be adjusted to your preference between 1.2 and 1.6bar. Please refer to section 2.1 for more information on how to change this setting.
3.2.4 Missed decompression stop button, you can modifiy the By pressing the information displayed in the bottom row. At each button press, the screen cycles through temperature, oxygen percentage, CNS and time of day (in lieu of the dive time; the latter has a 4-second time out after which the dive time is displayed again). WARNING Violating a mandatory decompression obligation may result in serious injury or death. If you ascend above the decompression stop depth by more than 0.
Nemo Wide Dive Computer 3.4 AFTER THE DIVE - In case of a dive violation, the corresponding symbol ( , ) is shown. In addition, the bar graph shows the calculated nitrogen load in the leading tissue. You can use this to gauge your progress in getting rid of nitrogen as the surface interval grows. Nemo Wide continues to perform decompressionrelated calculations (nitrogen release), for as long as there is desaturation time left.
3.5.3 SPECIAL SITUATIONS which gas is currently being used during the various phases of the dive. To use multiple gases, you will need to enable the gases and set the oxygen percentage and the ppO2max for each one. This is done in the same way as for G1, with the difference that for G2 and G3 you can turn a gas ON or OFF. Keep in mind that the MOD for G2 and G3 is the depth at which Nemo Wide will prompt you to perform the gas switch (see section 3.5.2 below).
Nemo Wide Dive Computer While the average depth is displayed, pressing and holding the enter button resets the average depth. Power supply: - CR2450 user-replaceable battery - battery life: 300-500 dives. Actual battery duration depends on the usage of the backlight and the water temperature. 4.2 Maintenance From any display, pressing the enter button restarts the stopwatch. 3.6.
