INTRODUCTION Welcome to OCEANIC and thank you for choosing the ATOM ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the ATOM 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. It contains information that you must become familiar with prior to diving with your ATOM.
OPERATING MODE STRUCTURE Unless it is operating in Dive Computer mode, the ATOM will be On in the default MAIN TIME (home time) mode (Fig. 1), like a standard Watch, until the Mode is changed. The M button is used to access 5 other Modes that include Alternate Time Mode, Countdown Timer, Chronograph (stop watch/lap timer), Daily Alarm, and Dive Computer Surface Mode. It is also used to revert to the Local Default Time display.
PC INTERFACE Interface with a PC is accomplished by connecting the ATOM (Watch) to a PC USB port using the USB Interface Cable provided. The same Cable is used for Upload and Download. There are 2 software programs on the CD together with a USB Driver and a separate User Manual that can be printed for personal use. The Settings Upload program is a convenient method for entering Time, Alarm, and Utility settings into the ATOM.
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.
SYMBOLS AND ALPHA NUMERIC GRAPHICS The upper line of digits on the LCD screen is used to convey alpha Messages such as Day of the Week, Operating Modes, items being Set, Gas and Transmitter identification, Altitude level, and Alarm identification. At times, the second line is also used to display alpha numeric graphics such as PO2 and On/Off. See Figure 3. The FO2 setting of Air will appear in the lower line.
Situations that will sound the Alarm include • Watch Daily Alarm reaches time set (disabled during Dive Modes). • Watch Countdown Timer reaches 0:00. • Air Time Remaining at 5 minutes, then again at 0 minutes. • Air Time Remaining becomes less than No Deco and O2 Time Remaining for 1 minute. • Turn Pressure at the Set Point selected (Transmitter 1). • End Pressure at the Set Point selected (active Transmitter). • Descent deeper than the Max Depth Set Point selected.
A single short beep (which cannot be disabled) is emitted for the following • Upon completion of a Hot Swap battery change. • Change from Delayed to Full Violation 5 minutes after the dive. 3 short beeps (which cannot be disabled) are emitted for the following • Air Time Remaining becomes less than No Deco and O2 Time Remaining.
POWER SUPPLY The ATOM (Watch) utilizes 1 - 3 volt CR2430 Lithium Battery. Transmitters use 1 - 3 volt, CR2 Lithium Battery. When used as a Dive Computer, the ATOM's battery should provide over 100 dive hours of operation if 2 dives are conducted during each dive period. The Transmitter's battery should provide over 1000 dive hours of operation.
To check the condition of the ATOM or a Transmitter's Battery, depress the S button for 2 seconds while in Dive Computer Surface Mode then release it.

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.
a BAR GRAPH The Bar Graph is used as a visual representation of nitrogen loading, or when accessed, oxygen accumulation. By default the Bar Graph (Fig. 25a) represents tissue loading of nitrogen, showing your relative no decompression or decompression status. This is referred to as the Tissue Loading Bar Graph (TLBG). Fig.
Displays associated with oxygen and the O2 Bar Graph will appear if FO2 for any Gas 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 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 Fig. 28 - Tank Pressure Within the available parameters that can be set (described later) are a TLBG Alarm and a Conservative Factor which if set ON reduces No Decompression times allowed.
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. Time and Date Displays Time displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes!). The colon that separates hours and minutes blinks once per second when the display is indicating real time (e.g.
a Fig. 32A - Temperature (Surface Mode) Temperature Display Ambient Temperature is displayed in Surface Mode (Fig. 32Aa) and in Log Mode, and can be viewed on a Secondary Display when accessed during dive modes (Fig. 32Ba). 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) SURFACE MODE Pressing and releasing the M button momentarily 5 times (< 2 seconds each time) while the Watch Local Default Time screen (Main Time or Alternate Time, whichever was selected as the Default) is displayed accesses the DIVE COMPUTER (DC) SURFACE MODE. Fig. 33 - Surface Mode (Pre Dive) Once accessed by preesing the M button, DC SURFACE MODE (Fig. 33) will remain on display for 2 hours during which time the ATOM will enter Dive Mode upon descent below 4 feet (1.2 meters).

PLAN MODE Oceanic strongly recommends that you review the Pre Dive Planning Sequence (PDPS) prior to every 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.
NOTE: When the Conservative Factor is set ON, No Decompression Dive times are reduced to the values of the next 3000 foot (915 meter) higher Altitude. Refer to the charts on pages 139/140. If FO2 for GAS1 is set for a numerical value (21 to 50%), the NITROX graphic and Maximum Operating Depth defined by the PO2 ALARM Set Point will be displayed.

Poor Reception Distance (greater than 6 feet/2 meters) Poor Reception Area Best Reception Area Poor Reception Area Poor Reception Area Fig.
POSITIONING OF THE ATOM The Transmitters emit low frequency signals that radiate outward in semicircular patterns that are parallel to the length dimension of the Transmitter. 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 Transmitters as shown on page 88 Figure 78.
An interruption of the 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.

Its resulting value will be displayed numerically along with the symbols NDC and TIME (Fig. 80a) and graphically as the Nitrogen Bar Graph (Fig. 80b). As you ascend from Depth following a dive that has approached the No Decompression Limit, the Nitrogen Bar Graph segments will recede as control shifts to slower compartments.
When the amount of time remaining before reaching the Oxygen Limit becomes less than the No Decompression Dive Time Remaining, calculations for that Depth will be controlled by Oxygen. Oxygen Time Remaining will then appear as the Dive Time Remaining display (Fig. 82a) as signified by the symbols O2 and TIME. As Oxygen Accumulation continues to increase, segments will add to the O2 Bar Graph. a Fig.
