The program within the i100 simulates the absorption of inert gases into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The i100 dive computer model is based upon the latest research and experi- ments in decompression theory.

GETTING STARTED CONTROL BUTTON The i100 utilizes 1 control button. The button allows you to select mode options and access specific information. It is also used to enter settings, and acknowledge the audible alarm. The symbols in the table below will illustrate how to proceed through the menus.

DIVE FEATURES DTR (DIVE TIME REMAINING) The i100 constantly monitors No Decompression status and O2 Accumulation, and will display whichever Time is the least amount available as DTR on the No Decompression Dive Main screen. The Time being displayed will be identified by the NO DECO or O2 MIN icons.
DEEP STOP When the Deep Stop selection is set to ON, it will trigger after descending deeper than 24 m (80 ft). The i100 then calculates (continually updating) a Stop Depth equal to ½ the Max Depth.

Log only stores a short summary of each dive. Alternately, the PC Download function stores much larger files for each dive. For this reason, it is normal to see dives stored in the i100's onboard Log that have already been overwritten in the PC Download Partition. If you do not remember to log or download your dives, they will be lost when the memory overwrites.

SURFACING Upon ascending to 0.9 m (3 ft) the i100 transitions to Dive Surface mode. For the first 10 minutes after a dive the i100 will continue to display the maximum depth and elapsed dive time. Once the surface time reaches 10 min- utes the i100 will display the standard Dive Surface screen.

If the current PO value of the gas is greater than 1.6, then a warning not to switch will display. The i100 will main- tain the current gas without switching. The diver may override the i100 and force the gas switch by pressing the button during the "HI PO2"...
If gas 2 is set on and the current gas is not the best gas when approaching the decompression stop zone, the i100 will warn you to switch gases. You must confirm the gas switch by holding the button for 2 seconds. If the gas switch is not confirmed within 30 seconds, no switch will be made.
> The added penalty (deco) time will have to be cleared in addition to the original required stop time. > If the total stop time (original + penalty time) is cleared the i100 will revert to normal No Decompression status with no further penalty.
Bar Graph will flash until it is silenced. ALT screens can be accessed and appear similar to Deco ALT screens. *DV 1 appears similar to CV but your i100 will now lock into Violation Gauge Mode 5 minutes after surfacing. Unlike CV, it will do this whether the stop times are cleared or not.
Also, the Up Arrow icon, UP message will flash, and Current Depth/Max Depth/DTR will only indicate dashes signifying that you are too deep. * The maximum functional depth Dive/Gauge/Free Mode 100 M (330 FT) is the depth at which the i100 can properly perform calculations or provide accurate display information.

PC INTERFACE The i100 is configured with a Data Port located on the side of the module that enables it to be connected to a PC through a USB port using a special interface cable that is available as an optional accessory. The USB Driver required for the interface system is downloadable from www.aqualung.com.

• Inspect the button, lens, and housing to ensure they are not cracked or damaged. WARNING: If damage or corrosion is found, return your i100 to an authorized Aqua Lung dealer, and DO NOT attempt to use it until it has received factory prescribed service.
• No adjustments are made during any time that the Wet Contacts are bridged. • When diving in high altitude waters from 916 to 4,270 meters (3,001 to 14,000 feet), the i100 automatically ad- justs to these conditions providing corrected depth, and reduced NO DECO and O2 MIN (O saturation) times at intervals of 305 meters (1,000 feet).
