NEMO WIDE DIVE COMPUTER

Congratulations! Your new Nemo Wide Dive Computer is the result of the latest Mares technology, and has been designed to guarantee maximum safety, efficiency, reliability and long life. Simple and easy to use, it is ideal for all types of dives. This manual contains all the instructions for its use. Mares thanks you for your choice and urges you to always practice safe and responsible diving. Enjoy! No part of this document may be reproduced, stored in a retrieval system, or transmitted in any form without the written permission of Mares S.p.A. Mares adopts a policy of continuing improvement, and therefore reserves the right to make changes and enhancements to any of the products described in this manual without notice. Under no circumstances shall Mares be held responsible for any loss or damage sustained by third parties deriving from the use of this instrument.

WARNING

In addition to the dive computer, also use a depth gauge, a submersible pressure gauge, a timer or watch, and dive tables.
Mares recommends scrupulous adherence to the simple rules of behavior listed below:
Responsible Diving Practices
Always plan your dives in advance. Never exceed the limits of your skill and experience. Go to your deepest planned depth at the beginning of the dive. Check your computer frequently during the dive. Comply with the ascent rate indicated by the computer. Always perform a safety stop between6and -3meters (-20 and -10 ft) for at least 3minutes. After any decompression stops, ascend very slowly to the surface. Avoid yo-yo dives (repeatedly ascending and descending underwater). Avoid strenuous activity during the dive and for half an hour after surfacing. When diving in cold water or after intense exertion, start ascending well before reaching the no-decompression limits. In the case of a decompression dive, prolong the decompression stop nearest the surface for safety. Repetitive dives should be separated by a surface interval of at least 2 hours. Your deepest dive should be the first one of the day. Avoid diving until the desaturation time deriving from the previous dive has elapsed. When doing repetitive dives for several consecutive days, take at least one day off from diving every week. In the case of decompression-stop diving, it is recommended to take one day off from diving every three days. Avoid decompression-stop dives and do not dive deeper than 40 meters (130 ft) unless you have been specifically trained in this type of technical diving. Avoid repetitive square profile dives (dives to a single depth) deeper than 18 meters (60ft). Always wait at least 12 hours, and preferably 24 hours, before flying after a dive, in accordance with the recommendations of the Divers Alert Network.

DANGER

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Before diving, make sure you have read and understood all parts of this manual.
The Nemo Wide dive computer is designed exclusively for recreational sports use and not for professional applications.

SET DIVE - DATA

Set Dive - Data FRESH / SALT
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). Use the <+> or <-> buttons to adjust the values. Press the <ENTER> button to save the changes made and move to the next selection. The <ESC> button exits to the previous set. Set Dive - Data - C Meters / F Feet You can select which units of measure you want to use: metric (C and m) or Imperial (F and ft). Use the <+> or <-> buttons to adjust the values. Press the <ENTER> button to save the changes made and move to the next selection. The <ESC> button exits to the previous set. Set Dive - Data - Del Tissue
Note If you have completed an EAN dive and wish to do a repetitive dive with air, set the computer for EAN with O2 at 21%. By so doing, the calculation of the % CNS will remain active.
The PF 0 program introduces no additional margin of safety. This icon, which appears during the dive, indicates whether a personal correction factor is enabled, and if so, its level. The current personal safety factor program (PF0, PF1, PF2) is displayed when you turn on the computer (Fig.6).
This section covers dives using compressed air as the breathing mix. When you see the word AIR, in Set dive - Mode, press the ENTER button. First of all, you can adjust the altitude. Set - Air - Altitude Altitude programs: P0 (0-700 m)(0-2296 ft) P1 (700-1500 m)(2296-4921 ft) P2 (1500-2400 m)(4921-7874 ft) P3 (2400-3700 m)(7874-12139 ft) When this item is accessed, it displays an indication of the current altitude program (P0, P1, P2, P3) (Fig.5). Use the <+> or <-> buttons to enter the desired value. Press <ENTER> to save the changes and advance to the next setting.
Use the <+> and <-> keys to set the desired value. Press <ENTER> to save your selection and move to the next set. Set - AIR - Fast Asc

A rapid ascent increases the risk of decompression sickness. This function enables or disables the Stop function in case of uncontrolled ascent, to prevent the dive computer from locking out after a rapid ascent. The feature can be particularly useful for instructors who need to practice emergency ascents. It displays the current setting (ON or OFF) when activated (Fig.7).
This option is intended only for highly experienced divers. Users who clear the residual nitrogen memory cannot use the instrument for repetitive dives. After this operation, do not dive with Nemo Wide if you have already dived within the previous 24 hours. This item is used for clearing the residual nitrogen memory of the tissue compartments. In Set Dive - Data mode, scroll until the blinking DELETE message appears. Press <ENTER> to call up the confirmation option, which will show a blinking NO message. Use the <+> or <-> buttons to change to OK. Then, once the OK message is displayed, press <ENTER> to clear the residual nitrogen in the tissue compartments. If you do not wish to clear the residual nitrogen memory in the tissue compartments, press <ENTER> when NO is displayed. The <ESC> button exits to the previous set. Press the <ENTER> button after the last item to return to the Set dive - Data menu. Now we can move to the Set dive - Mode using the <+> and <-> keys.
Note This setting cannot be changed during the dive. Therefore, carefully check all settings before going underwater.
Do not dive in mountain lakes without having first checked that the appropriate altitude program is selected. Set - Air - Personal correction factor
Use the <+> or <-> buttons to change the setting. Press <ENTER> to save the changes and advance to the next setting.
This function is intended only for highly experienced divers, who take full responsibility for the consequences of disabling the Stop on uncontrolled ascent.

Use the <+> or <-> buttons to change the setting. Press <ENTER> to save and return to Set Mode. The <ESC> button returns you to the main menu.

SET DIVE - MODE

Set Dive - Mode is used for setting the general parameters for the planned type of dive. Press ENTER to access this menu. Here you can select the dive you have planned and adjust the corresponding parameters accordingly. The last operational mode will appear selected from among: AIR EAN BOTTOM TIME Use the <+> and <-> keys to choose the dive type desired.

deco icon; current depth (in m or ft); depth of deepest decompression stop (in m or ft); duration of the deepest decompression stop; icons for the altitude program and personal correction factor (if enabled). 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: by pressing this button you can choose to view on the display bar: the ascent time; the temperature (in C or in F). or the ascent time; the duration of the dive so far (dive time) in digits <ENTER> button: temporarily displays (for 10 seconds) the dive parameter settings, just as they appear in Predive Mode. <ESC> button: When the <ESC> button is pressed during the dive, Nemo Wide will temporarily display the estimated deep stop required. The data displayed during the ascent may vary as a result of the divers behavior. Divers should check this data during the ascent for more precise information on the estimated stop. Note When the no-decompression time remaining is one minute, an audible alarm is sounded to indicate that the diver is about to exceed the no-decompression limits.
When the omitted deco stop alarms are triggered, desaturation of the simulated tissue compartments is halted and resumes only when the diver returns to the correct stop depth.
If the decompression stop depth is exceeded by more than 30 cm (11 inches), the downward triangle icon will flash; if it exceeds 1m (3 ft) it keeps flashing and an audible alarm will sound. These warnings remain active until the diver returns to the correct depth.
Never ascend above the correct decompression stop depth. Note
If the deco-stop overshoot exceeds one meter and lasts more than three minutes, the computer switches to Omitted Stop mode and the corresponding icon appears. In this case, if the diver attempts a repetitive dive after surfacing, Nemo Wide will only function as a depth gauge and timer (BT mode), and it will display the errors of the preceding dive.

DEEP STOPS

To minimize the likelihood of critical bubble seed formation, in the case of decompression dives or dives close to the no-deco limit, Nemo Wide prompts for a series of one-minute deep stops at different depths depending on the dive profile. Thus, when the conditions exist during the dive, Nemo Wide will display a deep stop icon (Fig.16).

Fig.20

If an AIR or EAN dive ends with an uncontrolled ascent or an omitted stop, Nemo Wide will restrict Dive - AIR and DiveEAN modes for 24 hours and will only allow the BOTTOM TIME operation mode.
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.
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
Effects on Central Nervous System Oxygen toxicity exposure is monitored by means of a CNS (Central System Calculation), based on currently accepted recommendations for exposure limits. This toxicity is expressed as a percentage value which ranges from 0% to 100%. The percentage CNS value is shown on the display. An alarm is triggered when it exceeds 75%, signaled by blinking of the value.

PREDIVE - EAN

This operating mode remains active until the diver goes below 1.2 meters (4 ft). The following details are displayed (Fig.22): type of dive (EAN); units of measurement (m-C or ft-F); type of water (Salt, Fresh); altitude program (if enabled) and level; personal correction factor (if enabled) and level; icon for %O2.
Before the dive, make sure you have correctly set up all the EAN dive parameters: percentage of oxygen in the mix and limit for the partial pressure of oxygen, which together determine the maximum depth of the dive.

Fig.23

Note The procedure for scrolling the items on the display is identical to that described in the section on diving with compressed air. Note The functions of the buttons are identical to those described in the section on diving with compressed air. 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. <-> button: by pressing this button you can choose to view on the display bar: the % O2; the % CNS. Or the temperature (in C or in F); the duration of the dive so far (dive time) in digits. <ENTER> button: hold down this button to display the dive settings with the same window as the Predive mode. <ESC> button: When the <ESC> button is pressed during the dive, Nemo Wide will temporarily display the estimated deep stop required. The data displayed during the ascent may vary as a result of the divers behavior. Divers should check this data during the ascent for more precise information on the estimated stop.

Fig.22

Nemo Wide should only be used for diving with oxygen rich mixes (EAN) by divers who have the necessary certification. Lack of appropriate diver training may result in possibly serious injury.
Note If Predive Mode persists for more than 10 minutes without any button being pressed, Nemo Wide will revert to Time mode. Note Before every dive, it is advisable to enter Set Dive mode and check all the parameter settings and the EAN parameters in particular.
The user is advised to carefully read the section on compressed air diving before reading the section on EAN dives.
We advise that when diving you always put Nemo Wide into Predive mode. Always check that the dive computer is switched on early in your dive.
MONITORING OF THE GENERAL DIVE PARAMETERS
Oxygen Partial Pressure When the diver reaches a depth at which the PPO2 exceeds the maximum limit entered in the corresponding parameter, (from 1.2 to 1.6 ATM), Nemo Wide triggers an alarm condition signaled by: blinking depth indicator; audible alarm. The alarm persists until the diver ascends enough for the PPO2 to return within the programmed limit.
DIVE EAN: NO-DECOMPRESSION DIVE
When the diver descends below 1.2 meters (4 ft) Nemo Wide automatically switches to Dive Mode and starts displaying the dive data. If this mode persists for more than 20 seconds, Nemo Wide will begin recording the dive details in the Log Book memory. The following details are displayed (Fig.23): current depth (in m or ft); no decompression time remaining, expressed in minutes; no deco icon; icons for the altitude program and personal correction factor (if enabled). the % O2; the % CNS.
DIVE EAN DECOMPRESSION STOP DIVE
The data displayed for decompression-stop diving with EAN are as follows (Fig.24): deco icon; current depth (in m or ft); depth of deepest decompression stop (in m or ft); duration of the deepest decompression stop; icons for the altitude program and personal correction factor (if enabled).
When the max PPO2 alarm goes off, ascend immediately until the alarm turns off.

Log Book mode is used for viewing the details of past dives on the display. The dives are organized as in the pages of a log book, with the number 1 assigned to the most recent dive, 2 to the preceding dive and so forth, until the memory is full. If the memory is full, when the user dives again the oldest record is deleted to free up memory for the new dive. Maximum capacity is approximately 40 hours of diving with profile points at twenty second intervals. To enter Log Book mode, scroll through the Main Menu until the LOGBOOK message appears on the display bar, and then press the <ENTER> button. Log Book The first page of the log book contains a summary history of dives with the following information (Fig.29): maximum depth reached;

The mineral glass is not exempt from scratches resulting from improper use.

Replacing the battery

Replacing the battery is a delicate operation, and requires close attention. We suggest that you visit an authorized Mares center. Mares declines all responsibility for any damage caused by replacing the battery. Unscrew the waterproof cover located on the back of the Nemo Wide, turning it counterclockwise (Fig34).
Note When the battery charge status is displayed, pressing the ENTER button will run an instant battery check.
Q: Are the 3 minutes of the safety stop included in the ASC time? A: The 3 minutes of the safety stop are not included in the ASC time. Q: What is a DEEP STOP? A: To minimize the likelihood of critical bubble seed formation, in case of decompression dives or dives close to the no-deco limit, Nemo Wide prompts for a series of one-minute Deep Stops at different depths depending on the dive profile. This is one of the special characteristics of the RGBM Mares-Wienke Algorithm. For more information visit: www.rgbm.mares.com Q: If I ascend above the depth for the DEEP STOP can I go back down to do the stop? A: If you surpass the stop by more than a meter (3 ft), the stop is canceled. Q: Why doesnt the DEEP STOP icon appear during the dive? A: The DEEP STOP only appears for decompression dives or dives close to the deco limit. Q: If I start my DEEP STOP and then go back down what happens? A: If you begin the DEEP STOP and then descend, the countdown stops. It resumes when you return to the DEEP STOP depth. Q: Why doesnt Nemo Wide turn off after a dive? A: If the no-fly period has not expired, after a dive Nemo Wide switches to TIME mode and shows information about the most recent dive. If you want to turn off the Computer, use the OFF command.

Fig.34

Remove the battery Note Do not discard the old battery in the environment. Mares respects the environment, and urges use of the appropriate separated waste collection service. Insert a new battery, Lithium CR 2450, making sure the polarity is correct.
Q: What happens if I replace the battery after a dive, before the desaturation time has run out? A: The residual nitrogen memory will be cleared, and the RGBM calculations for any previous dives will be aborted. The diver who used the computer in the previous dive must not dive for at least 24 hours. Q: What happens if I start a dive while Nemo Wide is still in OFF mode? A: If left in OFF mode when you begin the dive, Nemo Wide will still activate DIVE mode within 20 seconds of descending past 1.5 m (5 ft). Q: When I replace the battery, will my Log Book dive data be lost? A: No. Q: What happens if there is an uncontrolled ascent or omitted decompression stop during an AIR or EAN dive? A: Nemo Wide automatically switches to Stop mode at the end of the dive. The only Scuba mode that remains active in this case is Bottom time. Q: What indicates that Bottom Time mode was chosen by the user, rather than forced as a result of underwater behavior errors during the preceding dive?

Inspect the O-ring carefully, checking for any signs of damage, tearing or warping. If necessary, replace it with a new O-ring (Mares spare part Code 44200723). Position the gasket in the cover Set the cover on the Nemo Wide, making sure that the icons are positioned correctly (Fig.35).
