a maximum depth of 40 m, limit of sport dives. Exceeding these limits dramatically increases the possibility
of decompression sickness.
As a result of technological advancements, Cressi reserves the right to modify the device without prior

Introduction.
The computer Giotto by Cressi is a recreational advanced tool. It will provide all the necessary information
as regards depth, dive times, possible need of decompression, ascent rate and all the surface intervals
between dives. Nitrogen absorption and release is continuously processed by its sophisticated software,
taking into account the quantity of inert gas contained in the different mixtures that can be used. This
information is shown on the device's large display thanks to the PCD (Priority Compartment Digit Display)
system that allows an easy and direct "dialogue" between the diver and the computer, ensuring a clear
understanding of all the data needed at any given time and a perfect readability in any situation. The
computer is provided with clock and calendar and a versatile dive memory (logbook). The mathematical
model of Giotto can make saturation and desaturation calculations of dives carried out both with air and
with nitrox in any moment of the dive. In this last case you can set all the parameters related to the mixture
of our dive: from the maximum allowed PO2 value (between 1.2 bar and 1.6 bar), to the mixture's oxygen
percentage (FO2): between 21% and 99% of O2. Additionally, the device may be set by the user for either
metric (m-ºC) or feet system (ft- ºF).
Giotto computer can be connected to a personal computer by means of the Cressi interface (accessory)
and the related software (accessory). It is very important to carefully read this user manual and to perfectly
understand the meaning, otherwise serious damage can be caused to your health. This manual is intended
to guide the user to comprehend all the functions of the computer before using it in diving. The Giotto
computer by Cressi is always off; you can turn it on by pressing any key, while diving it automatically
activates at a depth higher than -1,2 m. Once switched on, the display shows the PRE DIVE mode and the
different functions are always set by means of the push-buttons, as seen below.
In order to understand all the computer's functions and their meaning, the manual is divided into five main
chapters, dealing with every possible use:
1 - General instructions and safety measures
2 – Computer control
3 – Before diving
4 – While diving
5 – On surface after diving
6 – Care and maintenance
