SET DIVE - DATA Set Dive - Data – FRESH / SALT WARNING Before diving, make sure you have correctly set the units of measurement. An incorrect setting may give rise to confusion during the dive, and hence to underwater behavior errors. To ensure maximum accuracy, you need to set Nemo Wide for either fresh water (“Fresh”) or seawater (“Salt”) as appropriate. Check this setting often, especially if you use the instrument in a variety of environments (lake, sea, swimming pool).
Nemo Wide dive computer Note The alarm for any deep stops always remains active. WARNING The audible alarms should only be disabled by experienced divers, who take full responsibility for this operation. EAN This section addresses dives using EAN as the breathing mix. When you see the word EAN in Set dive - Mode, press the button.
Fig. 12 The display bar shows you: • the temperature (in °C or in °F); • the duration of the dive so far (dive time) in digits. In this mode, the keys operate as follows: <+> button: • Press this button to display the maximum depth reached. Press it again to remove the maximum depth. • Hold down the button for 2 seconds to activate the display backlight. <-> button: • inactive in this mode.
Nemo Wide dive computer SAFETY STOP Fig. 17 If the maximum depth of a dive exceeds 10 meters, a “Safety Stop” is activated for the ascent. Nemo Wide suggests that divers take a 3-minute safety stop between 2.5 and 6 m in depth (8 - 19 ft), and will display the word “SAFEST”. A Timer located on the display bar indicates the time needed to complete the stop (Fig. 19). WARNING A rapid ascent increases the risk of decompression sickness.
these parameters in addition to the normal air dive parameters (discussed in the preceding section). This section will examine the general parameters for EAN dives monitored by Nemo Wide and the differences in how the data are displayed. WARNING It is essential to correctly set the oxygen percentage in the mix to ensure correct readouts of: • no decompression time remaining; • decompression stop times; • alarm on exceeding the maximum permitted PPO .
Nemo Wide dive computer • maximum depth; • icons for any mistakes made during the dive(omitted stop, uncontrolled ascent) • display of % CNS Fig. 27 Fig. 25 Fig. 24 In this mode the buttons function as follows: <+> button: • Press this button to display the maximum depth reached. Press it again to remove the maximum depth. • Hold down the button for 2 seconds to activate the display backlight.
PLANNING: SCROLLING OF NO DECOMPRESSION LIMITS This function allows the user to scroll through the no decompression limits, automatically taking into account the current residual saturation of the tissue compartments from a preceding dive.
Nemo Wide dive computer invite you to consult the special section of the www.mares.com web site. You can download the dedicated software and any updates from the web site. A: In the latter case, during the dive and in surface mode, the pertinent error icons are displayed along with the standard “Bottom Time” indications.
Turn clockwise, pressing the cover until the icons are aligned (Fig. 36). * Note Data refer to calculations performed with the following parameters: • Average length of every dive 45 min • 12 months of OFF-MODE. • Battery life is affected by the operating temperature. • At lower temperatures the battery life decreases. • The life of the battery will vary depending on use. Fig. 36 STRAP You can adapt the length of the strap to your wrist by cutting it to size along the special grooves (Fig. 37). Fig.
