WHICH MAY VARY DAILY. IT IS RECOMMENDED TO HAVE A COMPLETE MEDICAL EXAMINATION IMPORTANT: after a dive with Newton in Gage mode (depth gauge-timer), the device will not make saturation PRIOR TO STARTING ANY UNDERWATER DIVING ACTIVITY AND TO ASSESS ONE'S PHYSICAL and desaturation calculations for the next 48 hours. -
Page 4: Introduction
The default setting on the Cressi Newton computer-watch is the clock function. To switch to the dive computer, if it was not specially locked, press and hold the MODE button or scroll up to the ENTR DIVE menu. -
Page 5: How The Computer Works
SHUTDOWN OF THE DEVICE In order to reduce the consumption of the battery when the device is not in use, Newton can be switched off by pressing the LIGHT button for 5 seconds. The shutdown will cause the loss of the TIME and DATE, and will be possible only after the no-fly time. -
Page 6: Activating The Dive Computer
ACTIVATING THE DIVE COMPUTER ACCESS TO THE DIVE COMPUTER The dive computer can be accessed in two ways. The first is by pressing and holding the MODE button so AFTER 2’’ that the DIVE indication is displayed. Immediately after the MODE button is released the PRE DIVE screen will appear. -

8) SYSTEM: In this menu, you can set the unit of measurement of the computer and RESET it. 9) PRE DIVE: It is the main screen of the Newton computer, as well as the initial, and it is different from the others since it displays the time represented by the clock icon on the bottom at the screen. -

DOWN ( to go back to the menu) button until the screen shows the MODE SET (MODE-S) and setting the AIR BEEP or NITROX mode according to the type of dive you want to perform. Newton allows, in fact, all types of dives, Air dive, Nitrox dive, and dives with two different hyper-oxygenated mixtures selected, if previously set, in any... -
Page 9: Dive Set Mode: Oxygen Partial Pressure (Po2)
PARTIAL OXYGEN PRESSURE (PO2) Newton is factory set with a Partial Oxygen Pressure (PO2) value of 1.4 bar both for the air dives and Nitrox dives with one or two mixtures (Mix1 and Mix2) in order to ensure the maximum safety during any type of dive. -

LONG REMARK: The Newton computer is factory set on the MODE-S AIR dive program (air with PO2 1, 4). To be able to access the Nitrox parameters you need to set the MODE-S menu in position NITROX. Mix1 and Mix2 contain FO2 at 21% and the PO2 at 1.4 factory set by default. -
Page 11: Deep Stop
Some of those, during specific dives, support and require DEEP STOP, while others do not contemplate this type of decompression profile. Newton is factory set with DEEP STOP active. If you want to disable it, just press the UP button until you reach the DIVE SET menu;... -

(possible) series of dives and during the surface interval between two or more subsequent dives; in such case Newton takes into account the residual nitrogen, therefore reducing the times within the no decompression limits. To access the PLAN MODE, once the computer is on, press the UP button until PLAN is displayed. -
Page 13: System Mode: Units Of Measure Setting And Reset
Units of measure setting. The Newton computer can make the calculations by metric units (depth expressed in metres and temperature expressed in ºC), or in imperial units (feet and ºF). To change the unit of measurement, press the UP or DOWN button up to SYSTEM mode, then press the Mode button until the word "S.UNIT"... -

Nitrox mixtures in NITROX DIVE MODE (chapter DIVE SET MODE: Dive parameters setting). In this case the display will show the MX:1 icon which will stay on during the dive and as long as Newton remains set on NITROX MODE. Once the Nitrox program is on, you have to set the exact values of oxygen percentage (FO2) contained in the cylinder to be used during the dive, after having meticulously analysed its content, so the computer is able to adapt its computing algorithm to the new parameters. -

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 1.6 bar. Newton considers the 1.6 bar value as the Partial Pressure maximum allowable limit and, according to the mixture... -

NITROX DIVE MODE (chapter DIVE SET MODE: Dive parameters setting). In this case the display will show the word O2 which will stay on during the dive and until Newton does not change the setting again. You have to set the exact values of oxygen percentage (FO2) contained in the cylinders to be used during the dive, after having meticulously analysed its content, so the computer is able to adapt its computing algorithm to the new parameters. -

DEEP STOP. In order to avoid the risks related to the micro bubbles formed during the ascent, Newton is able to suggest a DEEP STOP of one or two minutes (in case of decompression dives) at variable depth depending on the dive profile. -
Page 18: Gage Function (Depth Gauge And Timer)
GAGE FUNCTION (depth gauge and timer) The Newton computer is equipped with a third dive computing program GAGE that does not perform any saturation and desaturation calculation, but it operates as a basic device, indicating dive depth and time, as well as some accessory data. -
Page 19: On Surface After Diving
LOG BOOK FUNCTION – DIVE LOG. Newton by Cressi stores data about the last 60 dives. Data is recorded every 20 seconds in the LOG BOOK. To display the previous dives, press and hold the UP button until the word LOG appears. The latest dive will be displayed in chronological order. -

Access the PC LINK Newton function by pressing the UP or DOWN button. Then, following the instructions it is easy to download all the data contained inside Newton as the profiles of the dives performed, to see them later reproduces, printed or modified by means of the software. -
