The programs within the EPIC simulate the absorption of nitrogen 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 EPIC dive computer model is based upon the latest research and experiments in decompression theory.

NTRODUCT ON Welcome to A RIS and thank you for choosing the PIC ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the PIC as a dive computer. It is equally important that you read the A RIS Dive Computer Safety and Reference Manual (Doc.

Page 34: Bar Graph
BAR GRAPH The PIC features one shared Bar Graph that represents either nitrogen loading, or when accessed, oxygen accumulation. By default the Bar Graph (Fig. 25a), referred to as the Nitrogen Loading Bar Graph (NIBG), represents your relative no decom- pression or decompression status.
Page 35 Displays associated with oxygen and the O2 Bar Graph will be displayed if FO2 for any Gas (1, 2, or 3) has been set at a value other than 'Air' (e.g., a numerical value) and the Alternate screen that displays oxygen related data is accessed. When the oxygen data screen is accessed during a NORM dive, the Bar Graph will show the maximum of either per dive accumu- lated oxygen or 24 hour period accumulated oxygen.
Page 36: Alpha / Numeric Displays
While you cannot provide a guarantee against the occurrence of decompression sickness, you may choose your own personal zone of caution based upon age, physique, excessive weight, etc., to reduce the statistical risk. Within the available NORM Mode parameters that can be set (described later) are a NIBG Alarm and a Conservative Factor which if set ON reduces No Decompression times allowed.
Page 37 Stop Depth During a No Decompression Safety Stop, the set (Fig. 30a) is displayed and during a Decompression condition, Ceiling Stop Depth the required is displayed. Time and Date Displays Time of Day and NORM/GAUG Mode displays shown in hour:minute format (i.e., 1:16 represents 1 hour and FREE Dive Mode displays 16 minutes, not 116 minutes!).
Page 38 Temperature Display Ambient Temperature can be viewed on the surface and during dives by accessing a Secondary Display (Fig. 32a). The lowest Temperature recorded during each NORM/GAUG dive is recorded in the LOG for that dive. NOTE: Each display represents unique pieces of information.

Page 49 Maximum Operating Depths affected by the PO2 limit set will not be displayed when FO2 for GAS 1 is set to AIR. Internally, the PIC keeps track of the oxygen loading so that if FO2 for GAS 1 is subse- quently set for a numerical value, the oxygen loading for previous AIR dives will be ac- counted for in the next Nitrox dive (during that dive period and series of repetitive dives).

NORM PLAN MODE AERIS strongly recommends that you review the Pre Dive Planning Se- quence (PDPS) prior to every NORM dive to help you Plan your dive as required to avoid exceeding no decompression or oxygen exposure limits. This is especially important for repetitive dives when the PDPS indicates adjusted dive times that are available for the next dive, based on residual nitrogen or oxygen accumulation (whichever is in control) following the last dive and surface interval.

Page 93: Link Interruption Underwater
POSITIONING OF THE EPIC The Transmitters (TMTs) emit low frequency signals that radiate outward in semicircular patterns that are parallel to the length dimension of the TMT. A coiled antenna inside the PIC receives the signals when it is positioned within a zone parallel to or at a 45 degree angle to the TMT as illustrated on page 92.
Page 94: Dive Time Remaining (Dtr)
An interruption of the TMT Link may also occur while the PIC is in an area within 3 to 4 feet (1 meter) of a running Dive Propul- sion Vehicle. The Link will be restored within 4 seconds after the Vehicle is shut off or the PIC is moved out of that area.
Page 95 No Decompression Dive Time Remaining (NDC) No Decompression Dive Time Remaining is the maximum amount of time that you can stay at your present Depth before entering a Decompression situation. It is calculated based on the amount of Nitrogen absorbed by hypothetical tissue compart- ments.
Page 96 Oxygen Accumulation Time Remaining (OTR) When the PIC is set for Nitrox operation, Oxygen Accumula- tion (saturation or exposure) during a dive, or 24 hour period, appears graphically as the O2 Bar Graph (Fig. 80a) when the Alternate #2 (O2) screen is accessed. As time remaining before reaching the Oxygen xposure Limit decreases, segments are added to the O2 Bar Graph.
Page 97 Air Consumption and Depth are continuously monitored and Air Time Remaining reflects any change in circumstances. For example, when a buddy starts breathing from your Octopus or you suddenly find yourself swimming against a strong current and begin breathing more rapidly, the PIC will recognize the change and adjust the Air Time Remaining accordingly.
Page 98: Variable Ascent Rate
You should immediately initiate a controlled Ascent while moni- toring your Tank Pressure. However, there is no reason to panic, the PIC has allowed for the Air necessary for a safe Ascent including the No Deco Safety Stop, if set On, and any Decompression Stops required.
Page 99: Elapsed Dive Time
At 60 FT (18 M) and shallower, the Warning will be given when Ascent Rates exceed 25 FPM (7.5 MPM). Ascent Rate Alarm At depths deeper than 60 FT (18 M), an Alarm will sound when Ascent Rates exceed 60 FPM (20 MPM).

Page 162 NOTE: The EPIC's O-ring must be a genuine AERIS part that can be purchased from an Au- thorized AERIS Dealer. Use of any other O-ring will void the warranty. Carefully place the Battery Hatch (with O-ring) into position on the rim of the Battery Compartment, then press it evenly and completely down into place.
