CLEAR (RESET)

The OCL is configured with a feature that allows nitrogen and oxygen calculations to be cleared.  

This is intended for 

facilities using the OCL for rental or training activities, not for general use by individual divers.

WARNING:  Reset after a dive and subsequent use for a repetitive dive conducted by the same diver 
could result in serious injury or death.

From the SN-ID Screen {see pg. 23} press S (< 2 sec) to access the Clear screen (if in NORM mode).

>> the graphics CLr NI-O2 with an arbitrary invalid code number entered by the factory will display, all solid. 

>> 2002 is the correct reset code to use. 

Proceed as follows, or press S (2 sec) to return to the SN screen

Reset procedure:

•  S (2 sec), at any time, to cancel the procedure and revert to the SN screen.

•  S (< 2 sec) to start the first 2 digits (left) flashing. 

•  A (hold) to scroll upward through the first digits (left) at a rate of 8 per second.  

•  A (< 2 sec) to step upward through the digits (left) one at a time.   

•  M (< 2 sec) to step back through the digits (left) one at a time.      

•  S (< 2 sec) to save the first 2 digits (left) and start the second 2 digits (right) flashing.

•  A (hold) to scroll upward through the second digits (right) at a rate of 8 per second.  

•  A (< 2 sec) to step upward through the digits (right) one at a time.   

•  M (< 2 sec) to step back through the digits (right) one at a time.      

•  S (< 2 sec) to save the reset code, clear the NI-O2 calculations, and revert to Watch mode.

ALTITUDE SENSING AND ADJUSTMENT

Altitude (i.e., ambient pressure) is measured upon activation and every 15 minutes until a dive is made.  

>  Measurements are only taken when the unit is dry.  

>  Two readings are taken, the second reading 5 seconds after the first.  The readings must be within 1 foot (30 cm) of each other to record that 

ambient pressure as the current Altitude. 

>  No adjustments are made during any time that the Wet Contacts are bridged.    

>  When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270 meters), the OCL automatically adjusts to these conditions 

providing corrected Depth, and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).  

>  When the Conservative Factor is set On, NDLs are calculated based upon the next higher 3,000 foot (915 meter) Altitude.  

>  All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times for 14,000 feet (4,270 meters).  

>  The OCL will not function as a Dive Computer above 14,000 feet (4,270 meters).

ADDITIONAL INFORMATION PERTAINING TO FREE DIVE MODE

•   Although breathing apparatus is not utilized for Free Dive activities, nitrogen tissue loading remains a factor.   Nitrogen loading is calculated 

based upon a fixed FO2 of Air.  

•   Since a user has the option of alternating between SCUBA and Free Dive activities within a 24 hour period, nitrogen calculations and the 

displayed value of No Deco Dive Time Remaining (NDC time) are carried over from one operating mode to the other, which permits the user to 

maintain awareness of nitrogen absorption and offgasing status.

•   The mathematical models currently used in the OCL are based on no decompression/decompression multilevel repetitive dive schedules.  

•   These algorithms do not take into account the physiological changes associated with the high pressures that competitive type Free diving can 

expose a diver to.

ADDITIONAL WARNINGS  

•  Ensure that you know which Operating Mode is selected (NORM, GAUG, or FREE) prior to commencing any dive.

•  Conducting Free dives within a 24 hour period after conducting SCUBA dives, combined with the effects of multiple rapid Free 

Dive ascents, increases your risk of decompression sickness.  Such activities may result in accelerated entry into decompression 

which could cause serious injury or death.

•  Combining competitive type Free dive activities that involve multiple descents/ascents with activities utilizing SCUBA during the 

same 24 hour period is not recommended.  Presently, there is no data relating to such activities.  

•  It is highly recommended that anyone planning to become involved in competitive type Free dive activities obtain proper 

instruction and training from a recognized Free Diving trainer.  It is imperative that the physiological affects be understood and 

the diver is physically prepared.
