ARCHIMEDE 1 27-09-2005 16:17 Pagina 130 1. - INTRODUCTION. 1.2. - SAFETY RULES. Congratulations on your purchase of an Archimede Cressisub dive computer. It is a sophisticated and comprehensive device designed to offer you utmost safety, efficiency, and reliability over time. 1.2.1. - Definition of Danger, Important, and Note. This manual highlights certain points of particular importance. Before reading these instructions, it is essential to properly understand the following definitions: 1.1.
27-09-2005 16:17 Pagina 131 fatigue, and dehydration. All these conditions and all those that can jeopardize your safety should be avoided. IMPORTANT: The use of this dive computer is strictly personal. The information it provides exclusively refers to the diver who has used it during the single or repetitive dives. IMPORTANT: this device should be used by certified divers only. No dive computer can actually replace proper training. Do remember that dive safety can be ensured by proper training only.
ARCHIMEDE 1 27-09-2005 16:17 Pagina 132 Cressi-sub reminds you that sport dives must always be kept within the safety limits and at maximum 131 ft depth, which is the standard maximum depth for recreational diving: if you exceed these limits, you significantly increase your DCS risk. It is extremely important that you carefully read and understand this User’s Manual. Otherwise,decompression sickness or death may occur.

By repeatedly pressing the M (Mode) button, you can scroll through all Archimede’s programs, and clearly display them on the alphanumeric UFDS display. Some of the programs also have sub-menus that can be accessed with the A and B ( , , i ) buttons. With these buttons you can also change surface data settings and with the B ( ) button, you turn on the display light. 2.2. - On Surface, prior to Dive.

This extra nitrogen is gradually eliminated and the balance resumed after a couple of days. where : • PO2 is the maximum partial oxygen pressure. It can be set by the diver with values from 1.0 bar to 1.6 bar (both values included), with changes of 0.1 bar, whenever you press the B ( ).
ARCHIMEDE 1 27-09-2005 16:17 Pagina 136 Once you get to the Max Depth (fig. 4 a) screen, press the A ( i ) button and select either the ON or OFF function with the B ( ) button. If you select ON, you can set the maximum depth in advance from 0 ft to 325ft, using the A and B ( i and ) buttons. IMPORTANT: Turn on the safety factor whenever you realize that there are factors likely to increase your DCS risk. You will thus perform a more conservative dive. • Max Depth is the maximum depth alarm (fig.
