INTRODUCTION Welcome to OCEANIC and thank you for choosing the ATOM 2.0 ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the ATOM 2.0 as a dive computer. It is equally important that you read the Oceanic Dive Computer Safety and Reference Manual (Doc. No. 12-2262) provided with your ATOM 2.0. It contains information that you must become familiar with prior to diving with your ATOM 2.0.
OPERATING MODE STRUCTURE Unless it is operating in Dive Computer mode, the ATOM will be ON in the default WATCH MAIN TIME (home time) mode (Fig. 1), like a standard WATCH, until the Mode is changed. The M button is used to access 4 other Modes that include Alternate Time Mode, Countdown Timer, Chronograph (stop watch/lap timer), and Daily Alarm. It is also used to revert to the Local Default Time display and access Computer Modes.
OPERATION AS A DIVE COMPUTER The ATOM 2.0, hereafter referred to as the ATOM, features 3 Dive Computer (DC) Operating Modes, NORM (Fig. 2A) which is used for Air and Nitrox dives, GAUG (Fig. 2B) used for dives in which Nitrogen-Oxygen calculations are not performed, and FREE (Fig. 2C) used for activities that do not use SCUBA. 2A Entering Settings and Plan Mode are only available in NORM SURF Mode which also allows access to Battery/Transmitter Status, Fly, Desat, Log, and History Modes.
PC INTERFACE Interface with a PC is accomplished by connecting the ATOM to a PC USB Port using the USB Interface Cable provided. The same Cable is used for Upload and Download. The software program is on the CD provided, together with a USB Driver. The program's Help serves as the user manual and can be printed for personal use. The Settings Upload program is used to check the ATOM's existing Settings and for entering Time, Alarm, and Dive Computer settings into the ATOM.
AUDIBLE ALARM Most warning situations that activate the Audible Alarm while operating in NORM or GAUG Mode cause the ATOM to emit 1 beep per second for 10 seconds, or until the situation is corrected, or it is acknowledged by momentarily pressing and releasing the S button (less than 2 seconds). After being acknowledged and the situation corrected, the Alarm will sound again upon reentry into the warning situation, or entry into another type of warning situation.
Tissue Loading Bar Graph at the segment Set Point selected. NORM/GAUG Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM) at 60 FT (18 M) and shallower. Loss of the active Transmitter Link signal for more than 15 seconds during a dive. Entry into Decompression Mode (Deco). Conditional Violation (above a required Deco Stop Depth for less than 5 minutes). Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that will not turn off when acknowledged Ascending above a required Decompression Ceiling Stop Depth for more than 5 minutes (referred to as a Delayed Violation). Decompression requires a Ceiling Stop Depth of 70 FT/21 M or deeper. Being on the Surface for 5 minutes after a Conditional Violation (Permanent Violation). BACKLIGHT To activate the Backlight - press the L button.
If voltage of the ATOM decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface display screens (fig. 3a) as an indication that the Battery should be changed prior to commencing a series of dives. If the ATOM's voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the message CHNG > BATT will scroll at the top of the display (Fig. 4). Operation will automatically revert to Main Time Mode.

WARNING: Prior to diving with the ATOM, you must also read and understand the Oceanic Dive Computer Safety and Reference Manual, Doc. No. 12-2262, which provides Important Warnings and Safety Recommendations as well as general product information.
BAR GRAPH a The ATOM 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 Tissue Loading Bar Graph (TLBG), represents your relative no decompression or decompression status. As your Depth and Elapsed Dive Time increase, segments will add to the TLBG, and as you ascend to shallower depths, the segments of the TLBG will begin to recede, indicating that additional no decompression time is allowed.
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 accumulated oxygen or 24 hour period accumulated oxygen.
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. a b Within the available NORM Mode parameters that can be set (described later) are a TLBG Alarm and a Conservative Factor which if set ON reduces No Decompression times allowed. FREE Dive Mode has a separate (fixed) TLBG Alarm. Fig.
During a No Decompression Safety Stop, the set Stop Depth (Fig. 30a) is displayed and during a Decompression condition, the required Ceiling Stop Depth is displayed. a c Time and Date Displays Time of Day and NORM/GAUG Mode displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes!). FREE Dive Mode displays are shown in minute:second format.
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. It is imperative that you understand the formats, ranges, and values of the information represented to avoid any possible misunderstanding that could result in error.
WARNING: Prior to diving with the ATOM, you must also read and understand the Oceanic Dive Computer Safety and Reference Manual, Doc. No. 12-2262, which provides Important Warnings and Safety Recommendations as well as general product information.
DIVE COMPUTER (DC) OPERATING MODES As described on page 12, the ATOM features 3 selectable DC Operating Modes NORM - for Normal Air or Nitrox dives GAUG - for dives with no Nitrogen/Oxygen calculations FREE - for dives with no SCUBA REMINDER: Once a dive is made in GAUG Mode, the ATOM is locked into that Mode for 24 hours after the dive.
If a dive has been conducted within the past 24 hours, the SURF MAIN screen for that Operating Mode (NORM, GAUG, or FREE) will be displayed. At any time while operating in Surface Modes, the ATOM will enter Dive Mode upon descent to 5 FT (1.5 M). During the 2 hour pre dive surface period, if the M button is pressed to access other screens in the Watch Mode sequence, Surface Mode must again be accessed prior to the first dive of a series (if WET ACTIVATION is set OFF).

Poor Reception Distance (greater than 6 feet/2 meters) Poor Reception Area Best Reception Area Poor Reception Area 92 Poor Reception Area Poor Reception Area Transmitter Signal Reception Guide
POSITIONING OF THE ATOM 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 ATOM 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. The ATOM cannot effectively receive a signal when it is held out to the sides of the TMT or held at distances greater than 6 feet (2 meters) in front of the TMT.
An interruption of the TMT Link may also occur while the ATOM is in an area within 3 to 4 feet (1 meter) of a running Dive Propulsion Vehicle. The Link will be restored within 4 seconds after the Vehicle is shut off or the ATOM is moved out of that area. When using a Strobe, a temporary interruption may occur shortly after the Strobe flashes. The Link will be restored within 4 seconds.
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 compartments. The rates each of these compartments absorb and release Nitrogen is mathematically modeled and compared against a maximum allowable Nitrogen level.
Oxygen Accumulation Time Remaining (OTR) a When the ATOM is set for Nitrox operation, Oxygen Accumulation (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 Exposure Limit decreases, segments are added to the O2 Bar Graph. Fig.
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 ATOM will recognize the change and adjust the Air Time Remaining accordingly.
You should immediately initiate a controlled Ascent while monitoring your Tank Pressure. However, there is no reason to panic, the ATOM has allowed for the Air necessary for a safe Ascent including the No Deco Safety Stop, if set On, and any Decompression Stops required.
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). At 60 FT (18 M) and shallower, the Alarm will sound when Ascent Rates exceed 30 FPM (10 MPM). The Audible will sound, the red LED will flash, and the message SLOW > SLOW will scroll on/off at the top of the screen.
Dive Main > Alternate 1 (ATR) > Alternate 2 (O2 Data, if set for Nitrox) A Secondary Display can be accessed by pressing the A button for 2 seconds. It will also automatically revert to the Dive Main Display after 3 seconds. Main > Secondary (Temperature and Time of Day) The S button is used to acknowledge and silence Alarms. The L button is used to activate the Backlight.

WET CONTACTS The Wet Contact Dive Mode Activation feature is active any time WET ACTIVATION is set ON. The ATOM is configured with contacts that will automatically activate Dive Mode when the space between the contacts is bridged by a conductive material (immersed in water) and it senses a Depth of 5 FT (1.5 M). Fig. 85 - MAIN TIME WET The contacts are the pins of the PC Interface Data Port and the stems of the Push Buttons.
NORM NO DECOMPRESSION DIVE MODE When the Wet Activation feature is set ON, the ATOM will enter the NORM No Decompression Dive Mode any time you descend to 5 FT (1.5 M). When the Wet Activation feature is set OFF, the ATOM will not enter Dive Mode upon descent unless it is operating in one of the NORM Dive Computer modes (menus) at that time. Modes such as Surface Mode, Plan, Fly, etc.
During the time that an Alarm is sounding, Alternate, Secondary, and Gas Switch Preview displays cannot be accessed. While the NORM DIVE MAIN screen is displayed, press/ release the A button (< 2 sec) to view NORM DIVE ALT 1. While the NORM DIVE ALT 1 screen is displayed, press/ release the A button (< 2 sec) to view NORM DIVE ALT 2. Press/hold the A button (2 sec) to view the Secondary Display (Temperature/Time).

If you descend below the required Decompression Ceiling before 5 minutes have elapsed, the ATOM will continue to function in Decompression Dive Mode. In this case, no off gassing Credit will be given, and for each minute above the Ceiling 11/2 minutes of Penalty Time will be added to Required Stop Time. The added Penalty (decompression) Time will have to be 'worked off' first, before obtaining off gassing credit.
DELAYED VIOLATION #2 (Fig. 100) The ATOM cannot calculate Decompression times for Stop Depths much greater than 60 FT (18 M) and offers no indication of how much time spent underwater would result in the need for a greater Stop Depth. If the Decompression obligation requires a Ceiling Stop Depth between 60 FT (18 M) and 70 FT (21 M), the TLBG will flash and the graphic message DECO > STOP > 60F (18M) will scroll at the top of the display. Fig.
Upon ascending above 330 FT (100 M), the Current Depth display will be restored, however Max Depth will only display 3 dashes for the remainder of that dive. Also, the Log for that dive will display 3 dashes as the Max Depth achieved. IMMEDIATE VIOLATION AND VIOLA GAUGE MODE If a Decompression Ceiling Stop Depth much greater than 60 FT (18 M) is required, an Immediate Violation Mode will be entered. This situation would be preceded by entering Delayed Violation Mode #2.
The ATOM will also enter an Immediate Violation Mode (Violation Gauge Mode) 5 minutes surfacing from a dive in which a Delayed Violation occurred. Violation Gauge Mode on the Surface does not allow access to the SET F, PLAN, FLY, and SAT features/screens. The countdown timer that appears when you try to access Time to Fly does not represent Time to Fly. It is only provided to inform you of the time remaining before normal ATOM Dive Computer operation can resume with full features and functions.
If a High PO2 condition occurs while in Deco Mode, the message HIGH > PO2 will replace the DECO HIGH PO2 When partial pressure of oxygen (PO2) becomes equal to, or greater than, 0.2 ATA less than the PO2 Alarm Set Point (a SET A Group setting); the red LED warning light will flash, the Audible Alarm will sound, and the message HIGH > PO2 will scroll until the Alarm is acknowledged/silenced. message until PO2 < 1.60. The graphic PO2 and UP Arrow will appear solid on the MAIN Display (Fig.
HIGH OXYGEN ACCUMULATION The O2 Bar Graph displays either oxygen accumulated during that nitrox dive, or during the repetitive nitrox dives you conduct during that 24 hour period, whichever of the two is greater at that time. The O2 Bar Graph allows you to monitor how close you are coming to the limits of oxygen exposure. Refer to page 167 for a Chart of NOAA Oxygen Exposure Limits.

Rotate the Battery Hatch clockwise 10 degrees using the special Battery Hatch Tool provided (Fig. 144), or by pushing the lower portion to the left while pushing the upper portion to the right (Fig. 145). Fig. 144 - BATTERY HATCH REMOVAL (Tool) Lift the Hatch with O-ring up and away from the Housing.
Transmitter Battery Removal Locate the Battery Hatch on the End of the Housing: Apply a coin to the recessed slot of the Hatch and turn it counter clockwise out of the Housing (Fig. 147). Remove the Battery from the Battery Compartment and discard according to local regulations governing disposal of Lithium batteries. Inspection Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
Inspection (continued) - Closely examine the threads of the Battery Hatch(es) and Housing(s) for any signs of damage that might prevent proper threading. Closely examine the inside of the Battery Compartment(s) for any signs of corrosion indicating entrance of moisture into the unit. If corrosion is found, return the ATOM system to an Authorized Oceanic Dealer, and DO NOT attempt to use it until it has received factory service.
NOTE: The ATOM's O-ring must be a genuine Oceanic part that can be purchased from an Authorized Oceanic Dealer. Use of any other Oring will void the warranty. Fig. 150 - ATOM BATTERY HATCH INSTALLATION 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. Maintain the Battery Hatch securely in place and turn it counter clockwise 10 degrees using the special Battery Hatch tool provided (Fig.
Place a new 3 volt, CR2, Lithium Battery (Duracell model DLCR2 or equivalent) positive (+) side down into the Battery Compartment with the negative end facing up/out (Fig. 153). Ensure that the Battery is properly oriented and the Hatch O-ring is evenly seated around the Battery Hatch. Carefully place the Battery Hatch with Spring into the Housing and turn clockwise slowly by hand to ensure proper threading. Apply a coin and tighten until secure.
INSTALLING A TRANSMITTER ON A REGULATOR To install the Transmitter on the Regulator First Stage: Remove the existing Pressure Gauge and High Pressure Hose, or the High Pressure Port Plug from the Port marked HP using the proper size Hex Key. Lightly lubricate the O-ring and Threads of the Transmitter fitting with a halocarbon based lubricant such as ChristoLube MCG111 (provided in Oceanic Battery Kits). Thread the Transmitter clockwise by hand into the Regulator's HP Port (Fig.
ALTITUDE SENSING AND ADJUSTMENT Prior to the first dive of a series of repetitive dives, ALTITUDE (i.e., Ambient Pressure) is measured upon activation of Dive Surface Mode and every 15 minutes until a dive is made or operation reverts to Main Time after 2 hours. > While it is operating in Watch Modes after a dive, measurements are taken every 15 minutes during the 24 hour period after surfacing. > Measurements are only taken when the unit is dry.
When the Conservative Factor feature is set ON, allowable dive times are calculated based upon the next higher 3,000 foot (915 meter) Altitude. All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times for 14,000 feet (4,270 meters). If the Conservative Factor is set ON while at Sea Level, calculations are based upon an Altitude of 3,000 feet. The ATOM will not function as a Dive Computer above 14,000 feet (4,270 meters).
