CHARACTERISTICS OF ICON HD
ICON HD is a color-display dive computer and
much, much more.
With ICON HD, you can:
• display your information digitally or
graphically during the dive;
• have a clear indication at all times of the
stops you need to make;
• display a map of the seabed during the dive;
• keep the compass active at all times, or use
it on demand;
• store and view .jpg format files;
• instantly review the logbook of your dives in
both digital and graphic formats;
• recharge the ICON HD battery anywhere,
even from your PC.
IMPORTANT WARNINGS
Before diving, make sure you have read and
understood all parts of this manual.

WARNING
As with all SCUBA equipment, Mares dive
computers are designed to be used by
trained, certified divers only. Failure to
fully understand the risks of using such
equipment may result in serious injury or
death. DO NOT use this dive computer or
any SCUBA equipment unless you are a
trained, qualified SCUBA diver.

WARNING
ICONHD is intended strictly for
recreational diving.

WARNING
In addition to the dive computer, also use
a depth gauge, a submersible pressure
gauge, a timer or watch, and dive tables.

WARNING
Never dive alone. ICONHD is not a
replacement for a dive buddy.

WARNING
Do not dive if the display appears unusual
or unclear.

WARNING
ICON HD must not be used in conditions that
preclude its use (e.g.: low or no visibility,
making it impossible to read the gauge).

WARNING
The dive computer cannot ensure against
possible decompression sickness. The dive
computer cannot take into account the
physical conditions of the individual diver,
which may vary from one day to the next.
For your safety, have a general medical
check-up before undertaking a dive.

WARNING
Always check the battery power level before
starting the dive. Do not dive if the display
indicates that the battery is low. Recharge
the battery. If this doesn't work, contact an
authorized center to replace the battery.

WARNING
Do not fly within 24 hours of your last dive,
and in any case wait until the ICON HD "no
fly" warning disappears.

WARNING
Recreational divers should not dive deeper
than 40m (130ft). Although this computer
will continue to provide information for
compressed-air dives deeper than 40m
(130ft), the risk of nitrogen narcosis and
decompression sickness (DCS) is greatly
increased.

WARNING
Never dive to depths greater than 40m
(130ft), and never take decompression
dives with ICONHD unless you possess
the specific certification (IANTD, NAUI,
PADI, DSAT, PSA, SSI, TDI, etc.) for deep
scuba diving to depths of more than 40m
(130ft) and fully understand the risks and
the skills that this type of dive requires.
This type of dive can entail a greater risk of
decompression sickness, even for the most
qualified and expert divers, and regardless
of the instrumentation or computer used.
Divers attempting these types of dives must
have completed a specialty course and gained
the necessary experience. The safety of a
dive can only be increased through adequate
preparation and training. Mares therefore
recommends using the dive computer
only after having completed a specialty
diver training course. Mares recommends
scrupulous adherence to the simple rules of
behavior listed in the next column.
RESPONSIBLE DIVING PRACTICES
• Always plan your dives in advance.
• Never exceed the limits of your skill and
experience.
• Check your computer frequently during
thedive.
• Do not exceed a safe ascent rate as
indicated by the dive computer.
• Always perform a safety stop between 6
and 3 meters (20 and 10 feet) for at least
3minutes during your final ascent.
• After any decompression stops, don’t exceed
the recommended ascent speed, 10 m/min
(30 ft/min).
• Avoid yo-yo dives (repeatedly ascending and
descending).
• Avoid strenuous activity during and after the
dive.
• Consider following a more conservative
profile when diving in cold water or when
exerting yourself heavily during the dive.
• In the case of a decompression dive, prolong
the decompression stop nearest the surface
for additional safety.
• Repetitive dives should be separated by a
surface interval of at least 1 hour.
• Your deepest dive should be the first one of
the day.
• When doing repetitive dives for several
consecutive days, take at least one day a
week off. In the case of decompression-stop
diving, it is recommended to take one day off
every three days.
• Avoid decompression-stop dives and do not
dive deeper than 40 meters (130 feet) unless
you have been specifically trained in this
type of technical diving.
• Avoid repetitive “square profile” dives (dives
to a constant depth) deeper than 18 meters
(60 feet).
• After a single dive wait at least 12 hours,
for multiple dives and/or multiple days
wait at least 18 hours and preferably 24
hours before flying, in accordance with
the recommendations of the Divers’ Alert
Network (DAN).
• Each member of a buddy team must have
his or her own dive computer and the whole
buddy team must follow whichever is the
most conservative profile.
