• 1. INTRODUCTION
1.1. OPERATING MODES
The functions of the Smart Apnea computer
can be grouped into two categories, each
corresponding to a specific mode of operation:
• watch mode: Smart Apnea is dry on the
surface. In this mode you can use it as a
normal watch. You can also change settings,
review your logbook, download to PC and
much more;
• dive mode: Smart Apnea monitors depth,
time and temperature; dive mode itself can
be broken down into 3 sub categories:
- pre-dive (Smart Apnea is on the surface
but actively monitoring ambient pressure,
so that it can begin to monitor a dive the
instant it is submerged below 1.2m/4ft);
- dive
- surfacing: Smart Apnea is on the surface
at the end of a dive.
1.2. USERREPLACEABLE BATTERY
Smart Apnea uses a CR2430 user-replaceable
battery. See section 4.2.1 for instructions on
how to replace it. Good quality batteries should
suffice for approx 200 hours of diving over a
two-year time span, depending on the usage of
the backlight and the temperature of the water.
Diving in cold water, usage of the backlight and
of the beeper increases battery consumption.
The display alerts you of the status of the
battery. The three possible situations are
described as follows:
- battery symbol not visible in the pre-dive
and dive display: the remaining battery
charge is adequate for diving;
- steady battery symbol on the display (dive
and pre-dive): there is enough charge for
a few more hours of diving, but you should
consider replacing the battery at the next
opportunity;
- blinking battery symbol on the display: the
battery is too weak for diving. If this happens
during a dive, you must not perform any
more dives before replacing the battery. If
you see the blinking battery symbol on the
surface, be aware that Smart Apnea will not
function as a dive computer and will not turn
on if submerged.
The level of the battery charge can also be
found on the “INFO” page (see section 2.6).
1.3. CONNECTING SMART APNEA TO
A PC OR MAC
To connect Smart Apnea to a PC or Macintosh
computer, use the optional clip and the USB
cable and Dive Organizer to download your
dives to a PC or Divers’ Diary to download your
dives to a Mac. Both software programs can be
downloaded from www.mares.com.
1.4. BUTTON OPERATION
Smart Apnea has 2 buttons, labelled up/enter
and down/esc. Each button can be pressed
and released to perform one function (up and
down) and pressed and held for one second to
perform a different function (enter and esc).
We’ll refer to them as upper and lower button
in the remainder of this manual.
On the surface pressing and releasing either
button allows to scroll through menus,
settings and values. Pressing and holding the
upper button enters into a menu or confirms a
setting, while pressing and holding the lower
button exits from a menu and goes up one
level.
During the dive, the upper button calls up the
max depth of the current dive whereas the
lower button calls up the time of day. Both
appear for 4 seconds only. From the main
watch display and in dive mode, press and hold
the lower button (
) to activate the backlight.
An overview of the button function both in
surface mode and during a dive is presented
here below.

1.5. WATCH DISPLAY
The watch display is the “home” display of
Smart Apnea. In this mode, the time of day is
shown in the middle row of the display while
date, temperature, seconds, wake-up time and
second time can be displayed at the bottom
by pressing the lower button. Note that the
temperature reading will be affected by your
body heat while you are wearing the watch. A
growing or diminishing ring of 60 dots around
the perimeter of the display represents the
seconds.
When the wake-up time is displayed, pressing
and holding the upper button turns the
wake-up alarm
or .
When the second time is displayed, pressing
and holding the upper button switches main
time and second time.
NOTE
At the end of the bottom row sequence there
is
with setting or . The setting
is changed by pressing and holding the upper
button while
is on the display. When
is , SMART will not start diving
even if exposed to 1.2m of depth for a
prolonged time. This allows you to perform
pool activities like swiming without constantly
activating the dive mode.
• 2. MENUS, SETTINGS AND
FUNCTIONS
This chapter describes in detail all menus,
setting and functions of the Smart Apnea
computer.
From the time of day display, pressing the
upper button allows you to scroll through the
following sequence of menus (note that once
inside the menu loop, pressing the lower
button scrolls through the menus in reverse
sequence):
- CHROnO: allows you to operate Smart
Apnea like a normal stopwatch;
- Countdown: turns Smart Apnea into a single,
multilap or continuous countdown timer;
- PRE dIVE: places Smart Apnea in the readyto-dive mode;
- SEt: allows you to view and change all
settings relating to the dive computer (SEt
dIVE) and to the watch (SEt tIME);
- LOG: allows you to access the detailed
history of the dives performed;
- PC: allows you to download dives to a PC or
Mac;
- INFO: allows you to view information about
software and hardware of your Smart Apnea.
The pre-dive mode puts the computer in a
ready-to-dive mode and ensures that Smart
Apnea starts to monitor the dive as soon as
a depth of 1.2m/4ft is reached. If you start
the dive without putting Smart Apnea into
pre-dive mode, it will start to monitor the
dive automatically but with a delay of up to 20
seconds from immersion.
The pre-dive display shows time of day and
temperature. The 4-digit number in the bottom
left corner is the set water density without the
decimal point. Refer to section 2.3.1 for more
information about setting the water density.
NOTE
- If you remain in pre-dive for longer than
3 minutes without pressing any button,
Smart will revert to normal watch function.
- It is recommended to put Smart into predive before submerging. Not doing so
can lead to a delay of up to 20s in Smart
monitoring the dive.
