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 flashes 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.

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 profile (with Earmarks), 

and set points. 

The PC/Mac programs also allow upgrade of select versions of the OCL's firmware (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.
