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.

OCL OPERATING MANUAL

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**.

• 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 operating 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):

OCL OPERATING MANUAL

DIVE COMPUTER OPERATING MODES

NORM Mode >> for Air and Nitrox SCUBA activity with 1 or 2 Gases.

GAUG Mode >> for SCUBA activity.

FREE Mode >> for breath hold diving activity with Depth/Time indication and decompression calculations shared with NORM Mode.

If no previous dive has been taken within the past 24 hours, NORM is the default upon access from Watch Mode. Others can be accessed while on the surface using the Set M (Dive Operating Mode) selection.

At any time while operating in Surface Modes, operation will enter the Dive Mode selected upon descent to 5 FT (1.5 M) for 5 seconds.

Operation will revert from Dive Mode to Surface Mode upon ascent to 2 FT (0.6 M) for 1 second.

During the rst 10 minutes after a NORM/GAUG dive, or 1 minute after a FREE dive, the Dive Main screen will remain on displaying Max Depth

and Elapsed Dive together with Surface Interval Time in place of Current Depth.

• During the rst 10 minutes (or 1 minute), Dive ALT screens can be viewed.

• A descent during the rst 10 minutes after surfacing from a NORM or GAUG dive, or the BDSI (Betwen Dive Surface Interval) time set after

surfacing from a FREE dive, is a continuation of that dive.

• After the 10 minute (or BDSI) interval has elapsed, a descent is then considered a new dive. Also, operation will revert to the Watch Main Time.

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.
