Always keep this manual with your Giotto. 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. [. . . ] Press the central Mode button and wait for a sound signal; dots and the word “DONE”!are displayed to confirm that the resetting of the device has been made. Then, it will return to the main screen. With the reset function, all the calculations related to desaturation eventually in course are set to zero. REMARK: Dive logbook, profile and historic memory remain stored in the memory even after the device's reset. REMARK: This function may be especially useful in case of device's renting by Diving Centres. DANGER: Do not reset your device if it has to be used to calculate subsequent dives!

REMARK: The Giotto computer is factory set on the AIR DIVE MODE function for air dives with the PO2 pressure set on 1. 4 and the FO2 fraction of the oxygen set on 21%. To set FO2 values different from Air 21% activate the NITROX DIVE MODE. REMARK: In case the computer does not turn on, this will automatically activate at a depth superior to 1. 2 m in a maximum time of 20 seconds. DIVING WITHIN NO DECOMPRESSION LIMITS AIR DIVE MODE FUNCTION: Dive with air. When set in AIR DIVE MODE, during a dive within the no-decompression limits, the display will show the following information: 1) Current deep value (Depth m. ). 2) Non decompression time (No Deco min. ). 6) Indicator or altitude level (if set). 7) Current temperature, expressed in ºC or ºF. Further important information may be obtained by pressing the right (>) button during the dive and represent: 1) Maximum PO2 set. 2) Oxygen percentage of the selected mixture (Air if FO2=21% and PO2=1. 4). 3) Maximum depth which can be reached depending on the maximum PO2 set. NITROX DIVE MODE FUNCTION: Dive with Nitrox. The Giotto computer keeps the setting of the percentage of Oxygen FO2 until the diver manually resets it to different values or until the DIVE MODE menu is set in AIR.
