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 THE DISPLAYED 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.

THE COCHRAN EMC-20H HAS MANY FEATURES THAT ENHANCE DIVER SAFETY

WITH MANY USER PREFERENCES.

THE DIVER CAN CUSTOMIZE THE COMPUTER TO BETTER REFLECT THE DIVE CONDITIONS

AND INDIVIDUAL STYLE OF DIVING.

MANY OF THESE FEATURES ARE PROGRAMMABLE AT THE DIVE SITE. OTHER

FEATURES WILL REQUIRE THE ANALYST SOFTWARE INTERFACE.

TOUCH CONTACT PROGRAMMING MODE

CAN ONLY BE ACCESSED WHEN THE UNIT IS IN THE SURFACE INTERVAL.

NOW, GRAB THE BATTERY REPLACEMENT TOOL THAT WAS INCLUDED WITH YOUR

COCHRAN EMC-20H.

IT CAN BE RECOGNIZED BECAUSE IT LOOKS AND SPENDS EXACTLY LIKE A U.S. QUARTER.

THIS FIRST TIME THROUGH THE PROCEDURE, WE ARE SIMPLY GOING TO LOOK AT THE SIX

PROGRAMMING MENUS.

WITH THE SURFACE INTERVAL SCREEN DISPLAYED, TOUCH OR BRIDGE CONTACTS 1

AND 2 WITH A COIN.

THE FIRST MENU TO APPEAR IS PdP, PREDIVE PREDICTION.

ANOTHER SIMILAR TOUCH WITH A COIN BRINGS THE InF, INFORMATION MENU.

THE THIRD COIN TOUCH BRINGS THE dEP AL, DEPTH ALARM MENU .

(Depth Alarm set to 124 feet)

THE NEXT TOUCH BRINGS THE Con, CONSERVATISM MENU.

Conservatism set to 15%

THE FIFTH TOUCH BRINGS UP THE TAC, TACLITE DWELL OR “ON TIME” MENU.

THE SIXTH TOUCH BRINGS THE LOG, LOGBOOK MENU.

ANOTHER TOUCH RETURNS YOU TO THE SURFACE INTERVAL SCREEN.

EACH PROGRAMMING OPTION OFFERS ADDITIONAL DATA OR OPPORTUNITIES FOR

PROGRAMMING YOUR PERSONAL DIVING PREFERENCES.

TOUCH CONTACTS 1 AND 2 WITH THE COIN AGAIN AND THE PdP MENU REAPPEARS.

NOW TOUCHING CONTACTS 1 AND 2 WITH A WET FINGER WILL ALLOW ADDITIONAL DATA

TO APPEAR ON THE SCREEN.

FOR EXAMPLE…

THE PREDICTED NDC TIME BEGIN AT 30 FEET, EACH ADDITIONAL WET FINGER TOUCH

INCREASES THE PREDICT DEPTH BY 10 FEET.

AS SHOWN HERE, AFTER TWO MORE TOUCHES THE PREDICTED TIME IS FOR A DEPTH OF 50 FEET.

THE NEXT WET FINGER 1 & 2 TOUCH STARTS THE 1’S DIGIT FLASHING.

The Digit beingProgrammed will

Flash Until it is set and youMove on to the

next Digit.

WHEN FLASHING, THE DIGIT IS INCREASED BY ONE WITH EACH COIN TOUCH BETWEEN CONTACTS 2 & 3.

THE NEXT 1 & 2 WET FINGER TOUCH STARTS THE 10’S DIGIT FLASHING AND MAKES IT

AVAILABLE FOR CHANGE.

A COIN TOUCH BETWEEN 2 & 3 INCREASES THE VALUE BETWEEN 0 AND 9.

TO PROGRAM THE 1OO’S DIGIT START IT FLASHING BY TOUCHING 1 & 2 WITH YOUR

WET FINGER.

WITH THE 100’S DIGIT FLASHING, BRIDGE CONTACTS 2 & 3 WITH A COIN UNTIL THE

DESIRED VALUE IS REACHED.

WHEN CONTACT 1 AND 2 ARE NEXT BRIDGED WITH A COIN, THE SCREEN ADVANCES TO

THE NEXT MENU ITEM. ONCE THIS HAPPENS, THE VALUES PROGAMMED ARE STORED IN

THE COMPUTER.

IT IS STRONGLY RECOMMENDED THAT YOU SCROLL THROUGH ALL OF THE PROGRAMMABLE

SELECTIONS PRIOR TO BEGINNING A DIVE TO ENSURE THAT THE SETTINGS ARE AS INTENDED.

IF SO…FOLLOW THE SAME PROCEDURE AND ADD A BIT OF CONSERVATISM TO YOUR DIVING. ADD FROM 0% - 50% TO

ANY OR ALL DIVES.

SUPPOSE THAT YOU’RE A BIT DEHYDRATED, A LITTLE FATIGUED,

SOMEWHAT OVERWEIGHT, AND HAVE AN OLD INJURY. MAYBE YOU HAVE ANOTHER

CONDITION WHICH MIGHT PREDISPOSE YOU TO DECOMPRESSION ILLNESS…..

THE NEXT 1 & 2 COIN TOUCH WILL END DEPTH ALARM PROGRAMMING AND OPEN THE MENU USED FOR PROGRAMMING A

PERCENT OF ADDITIONAL CONSERVATISM.

A SIMILAR SEQUENCE OF TOUCHING CONTACT 1 & 2 WITH A WET FINGER AND 2 &

3 WITH A COIN WILL ALLOW YOU TO PROGRAM THE 1’S AND 10’S DIGITS OF

CONSERVATISM.

A CONTACT 1 & 2 COIN TOUCH TAKES YOU TO THE NEXT MENU, TAC dl.

A WET FINGER TOUCH WHILE ON THIS SCREEN BEGINS THE PROCEDURE FOR

SETTING THE TACLITE “ON TIME” OR DWELL.

THE TACLITE IS ACTIVATED BY TAPPING ON THE FACE OF THE COMPUTER. THIS UNIQUE DESIGN LETS YOU READ THE DATA IN LOW-LIGHT CONDITIONS WITHOUT THE WORRIES

OF OVER-DEPLETING THE BATTERY.

ALSO, “NO WORRIES MATE” ABOUT A SWITCH THAT COULD POTENTIALLY BREAK OR LEAK.

YOU SIMPLY PROGRAM THE TACLITE TO REMAIN ON FOR WHATEVER TIME YOU

CHOOSE.

THE TACLITE FACTORY SETTING IS 10 SECONDS, YOU CAN CHANGE THIS TIME FROM

1-98 SECONDS. SETTING IT TO 00 AND THE TACLITE WILL NEVER TURN ON.

A SETTING OF 99 AND THE LIGHT IS ON WHENEVER THE EMC-20H IS AWAKE.

THE NEXT COIN TOUCH OF CONTACTS 1 & 2 OPENS THE LOGBOOK MODE.

THE WET FINGER BETWEEN 1 & 2 WILL ALLOW VIEWING OF DIVE DATA FOR THE MOST

RECENT 512 DIVES.
