PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678), Dive Computer with Free Dive Mode (U.S. Patent no. 8,600,701). Other patents
pending. User Setable Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy (Finland).
DECOMPRESSION MODEL
The programs within the OCL 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 OCL dive computer model is based upon the latest research and experiments in
decompression theory. Still, using the OCL, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding
decompression sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict
how your body will react to a particular dive prole.

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 (less than 2 seconds).
An LED Warning Light, on the edge of the housing, is synchronized with the Audible and ashes as the Audible sounds. It will turn Off when the
Alarm is silenced. The Audible and LED 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 activate only in NORM mode.
• 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 for the Gas in use**.
• 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.
• Entry into Decompression Mode**.
• 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 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.
A single short beep (which cannot be disabled) sounds when -
• 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 steady beep that will not turn off when
acknowledged -
• Ascent above a Deco Stop for more than 5 minutes.
• Deco requires a Stop Depth deeper than 60 FT/18 M.
• Upon Surfacing during a Conditional Violation.
PC/MAC INTERFACE
Interface with a PC or Mac, to allow uploading settings and downloading data, is accomplished by connecting the OCL to a PC or Mac USB Port
using the special Oceanic 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 OCL 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 PC and Mac programs can be used to set/change the selections in the Watch Time group, NORM/GAUG Set
A (Alarms) groups, NORM/GAUG Set U (Utilities) groupd\s, and FREE Set FA (Free Alarms) group. NORM Set Gas items must be set using the
control buttons.
Information available for retrieval (download) from the OCL to the PC/Mac programs 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 prole (with Earmarks),
and set points.
The PC/Mac programs also allow upgrade of select versions of the OCL's rmware (operating system software) after which the OCL resets all oper-
ating data. Since the upgrades require reset of the OCL, they are blocked during 24 hours after dives.

WATCH MODE
WATCH MAIN TIME
Selection of Main Time is a Set T (Time) menu item.
Time of Day and Date can be set when either Home or Away time is selected as the Watch Main.
Home Time is the current time at your home location and is normally selected as the Watch Main Time.
Away Time, set by Hour Differential, is the current Time at a remote travel location. Upon arrival at the location, Away
Time can be interchanged with Home Time to make it the Watch Main Time while visiting the travel location.
Dual Time is the second time (Away or Home) that can be displayed simultaneously with Watch Main Time with set On. It
is a +/- Hour Differential based on the Watch Main Time that is selected (Home or Away).
Once a differential is set, it will automatically change when Time of Day is changed. Also, when Away Time is selected to
be the Watch Main Time (while at a travel location), it can be changed by changing the differential instead of the Time of
Day.
MAIN TIME, information includes (Fig. 4A/B/C):

FLY/SAT TIME
Time to Fly is a countdown timer that begins counting down from 23:50 to 0:00 (hr:min) 10 minutes after surfacing from a
dive (NORM, GAUG, or FREE).
Time to Desaturate (SAT), also a countdown timer, provides calculated time for tissue desaturation at sea level taking into
consideration the Conservation Factor setting. It also begins counting down 10 minutes after surfacing from a dive (NORM
or FREE), counting down from 23 to 10 (hr only), then 9:59 to 0:00 (hr:min).
When the SAT countdown reaches 0:00, which will generally occur prior to the FLY countdown reaching 0:00, it will remain
on the display until the FLY countdown reaches 0:00.
> When other screens are accessed, the FLY and SAT countdowns continue in the background.
> SAT is not displayed after a Gauge or Violation dive.
> Desaturation requiring Times greater than 24 hours will display 24 - until it decreases to 23 (hr) .
> In the event that Time to Desaturate still remains at the end of 24 hours, operation as a dive computer will be canceled
and any Nitrogen/oxygen calculation and remaining SAT time will be cleared.
