Congratulations on your purchase of Giotto underwater computer, a sophisticated and complete device
which oers the utmost safety, eciency and reliability.
Always keep this manual with your Giotto.
MAIN FEATURES.
CRESSI RGBM algorithm. New algorithm created through a collaboration between Cressi and Bruce
Wienke, based on the Haldane model, integrated with RGBM factors for safe decompression calculations
in repetitive multi-day dives.
Tissues: 9 with saturation half-times between 2.5 and 480 minutes;
Dive program: Full processing of dive data, including decompression if applicable, for every dive
performed with Air or Nitrox.
Possibility of using two Nitrox hyper-oxygenated mixtures selected at any time of the dive.
Full setting of FO2 (oxygen percentage) and PO2 (partial oxygen pressure) parameters with the option to
set PO2 between 1.2 bar and 1.6 bar, FO2 from 21% to 50% for the rst mixture, and from 21% to 99% for
the second.
Option to take a Nitrox dive after one with air (even while desaturating).
Option to set Deco (decompressive computations) or Gage (depth gauge and timer).
Deep Stop can be turned on or o.
Large display with “PCD System” for perfect understanding and readability of values.
Replaceable protective display cover.
User-replaceable batteries.
Dive planning with manual safety curve scrolling.
User can switch unit of measurement from Metric (meters and °C) to Imperial (ft- °F) system.
Sound and visual alarms.
graphic CNS oxygen toxicity indicator.
Backlit display.
Built-in calendar and clock.
Log book (60 dives).
Dive history saved.
Option for full desaturation reset if needed, helpful when renting the device.
PC/Mac interface with general data and dive prole (optional).
GENERAL INSTRUCTIONS AND SAFETY MEASURES.
IMPORTANT: Read the instructions! Carefully read this user manual, including the safety measures
paragraphs. Make sure you perfectly understand the use, functions and limits of the device before using it!
DO NOT use the device without having read every part of this instructions booklet!
IIMPORTANT: this device is designed to be a dive aid and does not replace the use of dive tables.
‹ DANGER: AN UNDERWATER DIVING COMPUTER CAN NEVER COMPLETELY ELIMINATE THE RISK
OF DECOMPRESSION SICKNESS (EMBOLISM). IT MUST BE CLEAR THE AN UNDERWATER DIVING
COMPUTER CAN NEVER COMPLETELY ELIMINATE THE RISK OF DECOMPRESSION SICKNESS. IN
FACT, THE COMPUTER CANNOT TAKE INTO ACCOUNT THE PHYSICAL CONDITIONS OF THE
DIVER WHICH MAY VARY DAILY. IT IS RECOMMENDED TO HAVE A COMPLETE MEDICAL
EXAMINATION PRIOR TO STARTING ANY UNDERWATER DIVING ACTIVITY AND TO ASSESS ONE'S
PHYSICAL CONDITION BEFORE EACH DIVE. IT IS IMPORTANT TO REMEMBER THAT
CIRCUMSTANCES SUCH AS COLD TEMPERATURE (LESS THAN 10º C), NOT OPTIMAL PHYSICAL
CONDITION, MULTIPLE OR SUBSEQUENT DIVES, DIVER'S FATIGUE, CONSUMPTION OF ALCOHOL,
DRUGS, OR MEDICATION AND DEHYDRATION MAY INCREASE THE RISK OF DECOMPRESSION
SICKNESS. PLEASE AVOID ALL THESE SITUATIONS AS WELL AS ANY OTHER THAT MIGHT
ENDANGER YOUR LIFE: EVERYONE HAS TO BE RESPONSIBLE FOR ONE'S OWN SAFETY!
IMPORTANT: this device should be used only by properly trained and certied divers: No computer will, in
fact, replace proper underwater training. Please remember that a dive's safety is only guaranteed by a
correct preparation.IMPORTANT: Giotto computer by Cressi is designed for sport diving only and not for
commercial or professional use which require longer dive times and greater depths, consequently
increasing the risk of decompression sickness.
IMPORTANT: before using the computer, please check the battery life status and the indications on the
display. DO NOT dive if these indications are not perfectly clear and, especially, if the battery is low.
IIMPORTANT: while diving, be equipped with a depth gauge, a manometer, a diving timer or watch and
decompression tables. Always make sure that your diving cylinders' pressure is the correct one for the
planned dive and, while diving, often check the quantity of air in the cylinder, using the manometer.
DANGER: DO NOT DIVE AT HIGH ALTITUDES BEFORE SETTING THE CORRECT ALTITUDE LEVEL.
ONCE SET, PLEASE CHECK THE ALTITUDE LEVEL ON THE DISPLAY. REMEMBER THAT DIVING AT
ALTITUDES HIGHER THAN 3000 M ABOVE SEA LEVEL INVOLVES A REMARKABLE INCREASED
RISK OF DECOMPRESSION SICKNESS.
DANGER: BEFORE AN AIR TRAVEL, PLEASE WAIT UNTIL THE “NO FLY TIME” ICON ON YOUR
COMPUTER DISPLAY HAS DISAPPEARED.
IMPORTANT: The use of this device is strictly personal; the information it supplies refers, in fact,
exclusively to the individual who has used it during a dive or a series of dives.
DANGER: CRESSI DOES NOT RECOMMEND THE USE OF THIS DEVICE FOR DECOMPRESSION
DIVES. IF, FOR ANY REASON, THE NO-DECOMPRESSION LIMITS HAVE BEEN EXCEEDED, THE
GIOTTO COMPUTER WILL DISPLAY ALL THE INFORMATION RELATED TO DECOMPRESSION,
ASCENT AND SURFACE INTERVAL TIMES.
IMPORTANT: do not dive using Nitrox mixtures without having personally checked the contents and the
correct percentage of O2 (FO2). After doing so, set your computer with this value related to the mixture so
that it may process the decompression computations. Remember that the computer does not accept FO2
decimal gures.
IMPORTANT: Before diving, check device parameter settings.
DANGER: Giotto always keeps the latest oxygen setting. It is very important for diver's safety to always
check this parameter before each dive.
DANGER: CRESSI DISCOURAGES NITROX DIVES WITHOUT PROPER TRAINING. NITROX DIVES
WILL EXPOSE THE DIVER TO RISKS DIFFERENT FROM THOSE OF AIR DIVES, INCLUDING
SERIOUS PHYSICAL DAMAGES AND, IN EXTREME CASES, EVEN DEATH.
DANGER: FOR SAFETY REASONS, THE GIOTTO COMPUTER USES THE FACTORY SET LIMIT OF
PO2 SET AT 1.4 BAR EVEN FOR AIR DIVES. IF YOU NEED TO INCREASE THE SAFETY MARGIN,
YOU CAN SET PO2 TO LOWER VALUES, UP TO 1.2 BAR, WITH REDUCTIONS OF 0.1 BAR.
IMPORTANT: after a dive with Giotto in Gage mode (depth gauge-timer), the device will not make
saturation and desaturation calculations for the next 48 hours.
IMPORTANT: avoid all high-risk prole dives, such as the so-called "yo-yo" dive, reversed prole dives, or
repetitive dives in the same day or in consecutive days. They are potentially risky activities and involve a
high risk of decompression sickness!
IMPORTANT: Currently, no validated scientic literature allows diving more than twice a day for periods of
one or more weeks without the risk of decompression sickness. For your own safety, it is important to avoid
diving for more than two times a day. It is recommended to take a rest of at least 2 hours between two
subsequent dives. The next/repetitive dive shall be shallower and its minimum duration shall be of 15
minutes.
IMPORTANT: please use the most conservative safety factor (SF1 and SF2) any time you are aware of
factors that might increase the risk of decompression sickness. By doing so, you will dive in and safe way.
REMARK: in case of air travel, the device must be stored in the pressurised cabin.
REMARK: Cressi reminds that all sport dives must be conducted within the no decompression limits and at
