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).

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

 WARNING

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.

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.

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.

AIR

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:

(0-700 m)(0-2296 ft)

(700-1500 m)(2296-4921 ft)

(1500-2400 m)(4921-7874 ft)

(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.

Fig. 5

NOTE

This setting cannot be changed during the

dive. Therefore, carefully check all settings

before going underwater.

 WARNING

Do not dive in mountain lakes without

having ﬁrst checked that the appropriate

altitude program is selected.

SET  AIR  PERSONAL CORRECTION FACTOR

Nemo Wide includes a personal correction factor,

which you can set for added safety, to make the

algorithm more conservative. The correction

factor should be used by inexperienced divers,

for strenuous dives or when diving after a

prolonged period of inactivity.

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).

Fig. 6

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

 WARNING

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).

Fig. 7

Use the <+> or <-> buttons to change the

setting.

Press <ENTER> to save the changes and

advance to the next setting.

 WARNING

This function is intended only for highly

experienced divers, who take full

responsibility for the consequences of

disabling the “Stop” on uncontrolled

ascent.

SET  AIR  AL BEEP

This function enables or disables the audible

alarms.

When the computer is turned on, it displays

the current setting (“ON” or “OFF”).

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.
