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.

<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 their ascent for more

precise information on the estimated stop

(Fig. 13).

DIVE  AIR: “DECOMPRESSION

STOP” DIVE

If the diver does not ascend when the residual

time has expired, Nemo Wide switches to

“decompression stop” mode, indicated by the

appearance of the “deco” message and by an

audible alarm.

The following data are displayed in this mode

(Fig. 14):

Fig. 14

• “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).

• 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 diver’s 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.

TIME TO SURFACE ASC TIME

The ascent time is given by the sum of:

• duration of the various decompression

stops;

• Time required to ascend at an average

speed of 10 m/min (32 ft/min).

• Any deep stops.

DECOMPRESSION STOPS

Nemo Wide also checks that the

decompression stops are observed; two icons

graphically indicate how the diver must behave

(Fig. 15).

Fig. 15

• 2 triangles: correct decompression stop

depth;

• upward triangle: diver below decompression

stop depth, ascend!

• downward triangle: diver has ascended

beyond decompression stop depth, descend!

 WARNING

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.

 WARNING

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. 16

This display is helpful in planning the deep

stop during the ascent. When the diver

approaches a deep stop, Nemo Wide sounds

an audible alarm and the “DEEP STOP”

message appears on the display bar.

At the depth indicated a countdown will appear

indicating the time left in the DEEP STOP

(Fig. 17). There can be more than one deep

stop during a dive. This depends on the dive

proﬁle and on the type of decompression.
