Nemo Wide dive computer

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.

<-> button:

by pressing this button you can choose to view

on the display bar:

• total time to surface;

• the % CNS.

• the temperature (in °C or in °F);

• 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 diver’s behavior. Divers should

check this data during the ascent for more

precise information on the estimated stop.

 WARNING

To fully understand how to perform

decompression with EAN, the user should

also carefully read the corresponding

section for compressed-air deco stop dives.

NOTE

If you have completed an EAN dive and

wish to do a repetitive dive with air, set the

computer for “EAN” with O

at 21%. By so

doing, the calculation of the %CNS will

remain active.

SURFACING  EAN

When the measured depth is less than 1 m

(3 ft), Nemo Wide considers the dive to be

suspended (“Surfacing”) and halts the dive

timer. If the diver does not return below 1.5 m

(5 ft) within the next 3 minutes, Nemo Wide

considers the dive to be ﬁnished and records its

data in the log book memory. If the diver does

re-descend within 3 minutes, the dive continues

and the dive timer resumes from where it left

off.

Data displayed in Surface mode (Fig. 25):

• duration of the dive;

• maximum depth;

• icons for any mistakes made during the

dive(omitted stop, uncontrolled ascent)

• display of % CNS

FIG. 25

SURFACE MODE  EAN

The data displayed in Surface - EAN mode

is the same as that for Surface - AIR mode,

except for the addition of the % CNS value

(Fig. 26).

DIVE  BOTTOM TIME GAUGE

In this mode Nemo Wide functions as an

electronic timer and depth gauge, but does not

perform any calculations for no-deco limits or

for deco-stop times.

Responsibility for planning the no-

decompression limits or an adequate

decompression therefore lies entirely with the

user.

The details displayed in Predive and Surfacing

mode are the same as those already described

for air or EAN dives.

The data shown in Dive mode however are the

following (Fig. 27):

• dive time,

• current depth;

• ascent rate;

• temperature (in °C or in °F);

• the primary time.

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:

• this button is not enabled in this mode.

<ENTER> button:

• temporarily displays (for 10 seconds) the

dive parameter settings, just as they appear

in Predive Mode.

<ESC> button:

• this button is not enabled in this mode.

FIG. 27

 WARNING

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.

NOTE

After a dive in “BT” mode, the transition to

“AIR” or “EAN” mode will be disabled for

24 hours. (This lockout can be disabled by

clearing the residual nitrogen memory in

Set Dive - Data mode).

 WARNING

This option is intended only for highly

experienced divers. Users who clear the

residual nitrogen memory cannot then

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.

SURFACE MODE  BOTTOM TIME

The desaturation time and the delay before

ﬂying or traveling to high altitudes are

displayed in the same way as for Air or EAN

dives.

BOTTOM TIME WITH BEHAVIOR

ERROR

The following errors can occur during an air or

EAN dive:

• Uncontrolled ascent

• Omitted deco stop

In this case, Nemo Wide will inhibit the

Dive - AIR and Dive - EAN modes for 24 hours,

allowing operation in BOTTOM TIME mode only,

and will continue to display the underwater

behavior error in question.

The corresponding error icons are displayed in

Dive, Time and Logbook mode.
