ATOM 3.0 OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5216-r02 (9/6/11)
AUDIBLE ALARM
While operating in NORM or GAUG Mode, the Audible will emit 1 beep per second for 10 seconds when alarms strike, unless it is set Off. During that
time, the audible can be acknowledged and silenced by pressing the S button (< 2 sec).
An LED warning light on the housing is synchronized with the audible and flashes as the Audible sounds. It will turn Off when the alarm is silenced. The
audible and light will not be active if the audible is set Off (a group A setting).
FREE dive mode has its own set of alarms which emit 3 short beeps either 1 or 3 times which cannot be acknowledged or set Off.
Situations that will activate the NORM/GAUG 10 second Alarm include -
** Items apply only to NORM mode.
• Air Time Remaining (ATR) at 5 minutes, then again at 0 minutes.
• Turn Pressure at the Set Point selected (Transmitter 1 only).
• End Pressure at the Set Point selected (active Transmitter).
• Descent deeper than the Depth Alarm Set Point selected.
• Dive Time Remaining at the Set Point selected**.
• Elapsed Dive Time at the Set Point selected.
• PO2 at the Set Point selected**.
• High O2 of 300 OTU (100%)**.
• TLBG at the Set Point selected**.
• 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)**.
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required)**.
• Delayed Violation (Max Operating Depth of 330 FT/100 M is exceeded).
• A Gas Switch would expose the diver to PO2 => 1.60 ATA**.
• Watch Daily Alarm reaches time set (disabled during Dive Modes).
• Watch Mode Countdown Timer reaches 0:00.
A single short beep (which cannot be disabled) sounds -
• After 5 minutes on the surface after the Violation dive.
3 short beeps (which cannot be disabled) sound when -
• Ascent Rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or 26 to 30 FPM (7.5 to 9 MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set On).
• FREE Dive Depth Alarms 1, 2, 3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive TLBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Violation) - 3 beeps 3 times.
• Free Dive Mode Countdown Timer reaches 0:00 - 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second beep that will not turn off when acknowledged -
• Ascent above a Deco Stop for more than 5 minutes.
• Deco requires a Stop Depth of 70 FT/21 M or deeper.
• On the Surface for 5 minutes after a Conditional Violation.
PC INTERFACE
Interface with a PC, to allow uploading settings and downloading data, is accomplished by connecting the unit to a PC USB port using the special USB
interface cable.
The software program together with the USB driver required is on the Oceanlog CD, and can be downloaded from the OceanicWorldwide web site. The
program's HELP** serves as the user manual which can be printed for personal use.
**Prior to attempting to download data from your unit or upload settings to it, review the HELP section of the Oceanlog program. Recommended is to
print those sections of HELP that you consider appropriate for your Interface activities.
The settings upload portion of the Oceanlog program can be used to set/change the Main Time, Date, Set A group (Alarms), Set U group (Utilities), and
FREE mode items using the same interface system. FO2 must be set using the control buttons.
Information available for retrieval (download) from the unit to the PC download portion of the program includes dive data such as number, surface interval
time, maximum depth, elapsed dive time, no deco status, start date/time, lowest temperature under water, sampling rate, dive profile, and set points.
The Oceanlog program also allows upgrade of select versions of the firmware (operating system software) after which the unit resets all operating data.
Since the upgrades require reset of the unit, they are blocked during 24 hours after dives.
