Mares Smart Dive Computer - Dive Settings Configuration

7
AIR is the equivalent of setting EAN to 21%
and a ppO
2
max of 1.4bar, but simplifies the
display a bit by not showing the CNS (its value
however is calculated in the background and if
needed the 75% warning and the 100% alarm
are triggered).
When selecting EAN, you are taken to
a submenu in which you can define the
percentage of oxygen in the mixture (%O
2
) and
the maximum value of oxygen partial pressure
(ppO
2
max) for up to two breathing mixes. The
maximum possible value for the ppO
2
max is
1.6bar. Most training agencies recommend not
to exceed a value of 1.4bar.
Once inside this menu, press either button to
change the O
2
% and observe how this affects
the maximum operating depth (MOD). Then
press and hold the upper button to move on to
the ppO
2
max and use either button to change
the value, again noticing how this affects the
MOD. Press and hold the upper button again to
save the setting.
This leads you to the G2 OFF screen. Press and
hold the lower button to exit the menu or go to
section 3.5 for information about diving with
more than one gas.

WARNING
- Diving with Nitrox may only be
attempted by experienced divers after
proper training from an internationally
recognized agency.
- Before every dive and after changing
the tank, you must make sure that
the set oxygen concentration in Smart
corresponds to the oxygen concentration
in the tank. Setting the wrong oxygen
concentration can lead to serious injury
or death.
See chapter 3.5 for more information about
diving with more than one gas.
2.4. SEt
Smart’s SEt menu allows you to change
settings. Once inside this menu, press either
button to scroll between two submenus: SEt
dIVE, where you can set parameters pertaining
to the dive, and SEt tIME, where you can set
parameters pertaining to time and date.
Press and hold the upper button to enter a
menu, then press either button to scroll up and
down between available options or to increase
or decrease the value of a setting. Then press
and hold the upper button to confirm the
change in setting. Press and hold the lower
button to go up one level in the menu tree.
MENU Description
SEt dIVE
- LGHt
Allows you to set the duration
after which the backlight
turns off automatically. You
can set this between 1 and 10
seconds.
- P FCt
Allows you to choose between
the standard algorithm (P0)
and an increasingly more
conservative one (P1, P2).
- ALt
Allows you to set the
algorithm into altitude mode
when diving in mountain
lakes.
- WAtR
Allows you to choose
between salt and fresh water.
- UN:tS
Allows you to choose
between metric (m, °C) and
imperial (ft, °F) units
- FASt
Allows you to turn off the dive
violation due to uncontrolled
ascent. This is for dive
instructors only, who may
find themselves in such a
situation because of their
teaching requirements.
- ALRM
Allows you to turn on or off
all audible alarms of Smart.
- ErASE
Allows you to reset the
nitrogen saturation to zero,
thereby erasing the effects
of a previous dive. This is
only for people who plan
to lend their computer to
another diver who has not
performed a dive within the
last 24hours.
- dEEP
Allows you to turn off the
calculation and display of the
deep stop.
SEt tIME
Allows you to set the time
format, time and date, wake-
up alarm and second time.

2.4.1.1. LGHt (BACKLIGHT)
Smart has a backlight which can be activated
in case of low ambient light. The backlight is
activated by pressing and holding the lower
button. During a dive, the backlight will stay on
for the duration defined in this menu. You can
choose between 1 and 10 seconds.
