LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 6 SESS ONE’S OWN PHYSICAL CONDITION BEFORE EACH DIVE. CIRCUMSTANCES SUCH AS COLD WATER TEMPERATURE (LESS THAN 50F), POOR PHYSICAL CONDITION, MULTIPLE DIVES IN SUBSEQUENT DAYS, WEARINESS, USE OF ALCOHOL, DRUGS, OR MEDICATION AND DEHYDRATION MAY INCREASE THE RISK OF DECOMPRESSION SICKNESS.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 7 to the planned dive and, while diving, often check the cylinders’ air capacity by means of your manometer. DANGER: DO NOT DIVE AT HIGH ALTITUDES BEFORE SETTING THE CORRECT ALTITUDE. ONCE SET, PLEASE CHECK THE ALTITUDE LEVEL ON THE DISPLAY. PLEASE REMEMBER THAT DIVING AT HIGHER ALTITUDES THAN 9.842 FT. ABOVE SEA LEVEL INVOLVES A REMARKABLE INCREASED RISK OF DECOMPRESSION SICKNESS.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 8 WARNING: Do not dive using Nitrox mixtures without checking the contents and correct O2 percentage (FO2). After doing so, set your computer with the mixture(s)’ value so that it may process the decompression computations. Please be advised that the computer only accepts FO2 values to the nearest whole number. WARNING: Before diving, check instrument parameter settings. DANGER: Leonardo always keeps the latest oxygen setting set.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 9 WARNING: avoid any dive presenting very risky profiles, such as "yo-yo" dives, dives with reversed profiles or several subsequent dives during subsequent days, since they are potentially dangerous and present a higher risk of decompression sickness! WARNING: Currently, no validated scientific literature allows to dive more than twice a day for periods of one or more weeks without the risk of decompression sickness.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 10 As a result of technological advancements, Cressi reserves the right to modify the instrument without notification. Introduction. The Leonardo computer by Cressi is a multifunctional instrument for sport diving. It will supply any wanted information on depth, dive times, decompression status, ascent rate and surface interval times between dives.

The mathematical model of Leonardo can make saturation and desaturation computations of dives carried out both with air and with Nitrox, whose parameters can all be set: from the maximum allowed PO2 value (between 1.2 bar and 1.6 bar), to the mixture’s oxygen percentage (FO2) between 21% and 50% of O2.

Additionally, the instrument may be set by the user for either metric (m-°C) or feet system (ft-°F).
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:10 13 COMPUTER CONTROL OPERATION OF THE LEONARDO COMPUTER Leonardo is provided with a user friendly display, which “escorts” the diver during any operation.

WARNING: After a dive in GAGE mode, the instrument will not make saturation and de-saturation computations for the following 48 hours. WARNING: The Leonardo computer is designed for sport diving only.

LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 36 WHILE DIVING COMPUTER FUNCTIONS (im. 14-15) The computer can be set with three different functions: 1) DIVE AIR if dives are performed with air and you want to use a decompression computation. 2) DIVE NITROX if dives are performed with Nitrox and you want to use a decompression computation.. 3) GAGE if you do not want to use a decompression computation.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 37 Additional important information may be obtained by pressing the button during the dive: 1) Maximum PO2 set. 2) Oxygen percentage of the selected mixture (Air if FO2=21%); 3) Maximum depth which can be reached depending on the maximum PO2 set. 4) Safety Factor SF. DIVE NITROX FUNCTION: Dive with Nitrox (im. 15) The Leonardo computer keeps the setting of the percentage of Oxygen Fo2, until the diver manually resets it to different values.

DANGER: the use of the computer with hyper-oxygenated (nitrox) mixtures is exclusively intended for divers who have attended a full training course on the use of such mixtures.

LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 40 DANGER: Do not dive with cylinders containing Nitrox mixtures without checking their oxygen percentage. WARNING: : Check the FO2 value set on the computer prior to diving! This is done on surface by means of the main screen PRE-DIVE and the DIVE SET screen which allow visualization of the previously set parameters. WARNING: Under the same dive conditions, a Nitrox mixture requires longer no decompression times than air.

NOTE: The result of the oxygen exposure computation is approximated to the nearest whole number. It is important to understand, monitor, and control the oxygen toxicity level. In order to reduce the risk of oxygen toxicity, Leonardo displays a graphic bar, easy to read in any situation.

Oxygen toxicity may be caused both by an excessive exposure (CNS toxicity, seen in the previous chapter) and by exceeding the maximum Po2, which is exceeding the maximum depth allowed by the mixture used. As already seen, the PO2 limit value is set by the diver in a range between 1.2 bar and 1.

(im 19) The ascent rate is shown on the display by an arrow indicator at the centre, operating according to the table on the picture 18: If, during surfacing, the maximum allowed ascent rate is exceeded, the display will show three arrows, showing the increasing level of the ascent rate. Additionally, the alarm will sound, the SLOW icon will flash, as well as the arrow indicator.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 46 NOTE: During the safety stop, the maximum depth can be displayed pressing the button. DANGER: At the end of the safety stop, many divers use to quickly reach the surface, sometimes even inflating the Buoyancy Control Device. It is a very severe error which may lead to decompression sickness. The last meters before surface in fact are the most critical and the percentage variations of the pressure are significant.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 47 If the diver omits it, the warnings will be deleted and the computer recalculates ascent planning without that stop.

Cressi discourages the use of this instrument for decompression dives. In the event that you have exceeded the no decompression limits, Leonardo will assist with specific information related to surfacing and related decompression information.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 51 DANGER: NEVER ascend above a decompression depth. To avoid this situation, you should ascend to a depth slightly deeper than the stage decompression depth requirement. You should consider the amount of gas needed to successfully complete all decompression requirements. During rough sea conditions, it may be difficult to comply with the decompression stage requirements without exceeding it.

LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 55 WARNING: Leonardo is designed for sport diving only. It is not intended for commercial or professional use, requiring longer dive times and greater depths. Diving beyond the parameters of sport diving dramatically increases the risk of decompression sickness. DANGER: Cressi discourages diving with gaseous mixtures other than air without proper training.
LEONARDO LIBRETTO 105X80 INGLESE:Layout 1 7-06-2011 10:11 56 WARNING: The computer will not perform any saturation and de-saturation computation during the remaining 48 hours elapsing from the end of the dive performed with the GAGE function. DANGER: Should you decide to reset the instrument, the nitrogen memory will be cancelled. Therefore, the instrument will not be able to compute a subsequent dive as such. Before using this function, wait for at least 48 hours after the last diving activity.
