AN AUDIBLE ALARM WILL BE ISSUED

SHOULD A NO-DECOMPRESSION LIMIT BE EXCEEDED, THE COMPUTER

AUTOMATICALLY ENTERS THE DECOMPRESSION MODE.

STAYING AT THE SAME DEPTH OR DEEPER AFTER THE 2 MINUTE WARNING WILL

CAUSE THE UNIT TO ENTER THE DECOMPRESSION MODE.

COCHRAN DOES NOT INTEND FOR THIS

UNIT TO BE DELIBERATELY USED FOR

DECOMPRESSION DIVING.

HOWEVER, IF YOU PLAN TO PERFORM

DECOMPRESSION DIVES, WE RECOMMEND THAT

YOU HAVE ADEQUATE TRAINING, BACK UP

TABLES, AND AT LEAST TWO IDENTICAL

COCHRAN COMPUTERS.

DECOMPRESSION MODE

WHILE IN DECOMPRESSION MODE, THE VALUES IN THE UPPER LEFT HAND REMAIN TIME BOX ALTERNATE BETWEEN THE TIME REQUIRED AT THAT CEILING DEPTH AND

THE TOTAL TIME REQUIRED TO COMPLETE ALL DECO STOPS.

AT THE 10 FOOT CEILING, TOTAL TIME AND STOP TIMES MAY BE THE SAME AND APPEAR

NOT TO ALTERNATE.

DECOMPRESSION MODE

THE CEILING REPRESENTS A DEPTH ABOVE WHICH THE DIVER MUST NOT ASCEND, UNTIL SUFFICIENT TIME HAS PASSED, IN ORDER TO

MINIMIZE THE RISKS OF DECOMPRESSION SICKNESS.

THE DEPTH OF THE REQUIRED CEILINGS START AT 10 FEET AND INCREASE IN 10

FOOT INCREMENTS AS THE DECOMPRESSION OBLIGATION INCREASES.

DECOMPRESSION MODE

IN DECOMPRESSION MODE, THE NDC LEGEND AND VALUES ARE REPLACED BY DECOMPRESSION TIMES, DEC.

WHAT ARE BENCHMARKS?

Click here to return to Touch Contact Programming Return

BENCHMARKS ARE CONDITIONS THAT MUST BE SATISFIED BEFORE THE GAS SWITCH FROM THE DEFAULT BLEND TO THE

DECO BLEND WILL OCCUR.

THE “Dec b” BENCHMARK IS THE BOTTOM TIME OF THE DIVE AFTER WHICH THE GAS SWITCHING WILL BE ENABLED. ONCE

THE PROGRAMMED TIME HAS BEEN SATISFIED, THE GAS SWITCH WILL BE CONTROLLED BY DEPTH

THE “Dec d” BENCHMARK IS THE DEPTH OF THE GAS SWITCH. ONCE THE DIVER ASCENDS ABOVE THE PROGRAMMED DEPTH,

THE GAS SWITCH FROM THE DEFAULT BLEND TO THE DECO BLEND WILL OCCUR. IF BENCHMARK “Dec b” IS NOT SATISFIED

THERE WILL NOT BE A GAS SWITCH.

PLEASE READ AND UNDERSTAND THE OWNER’S MANUAL.

COCHRAN DOES NOT INTEND FOR THIS

UNIT TO BE DELIBERATELY USED FOR

DECOMPRESSION DIVING.

HOWEVER, IF YOU PLAN TO PERFORM

DECOMPRESSION DIVES, WE RECOMMEND THAT

YOU HAVE ADEQUATE TRAINING, BACK UP

TABLES, AND AT LEAST TWO IDENTICAL

COCHRAN COMPUTERS.

DECOMPRESSION MODE

WHILE IN DECOMPRESSION MODE, THE VALUES IN THE UPPER LEFT HAND REMAIN TIME BOX ALTERNATE BETWEEN THE TIME REQUIRED AT THAT CEILING DEPTH AND

THE TOTAL TIME REQUIRED TO COMPLETE ALL DECO STOPS.

AT THE 10 FOOT CEILING, TOTAL TIME AND STOP TIMES MAY BE THE SAME AND APPEAR

NOT TO ALTERNATE.

DECOMPRESSION MODE

THE CEILING REPRESENTS A DEPTH ABOVE WHICH THE DIVER MUST NOT ASCEND, UNTIL SUFFICIENT TIME HAS PASSED, IN ORDER TO

MINIMIZE THE RISKS OF DECOMPRESSION SICKNESS.

THE DEPTH OF THE REQUIRED CEILINGS START AT 10 FEET AND INCREASE IN 10

FOOT INCREMENTS AS THE DECOMPRESSION OBLIGATION INCREASES.

DECOMPRESSION MODE

IN DECOMPRESSION MODE, THE NDC LEGEND AND VALUES ARE REPLACED BY DECOMPRESSION TIMES, DEC.
