12. IF A DIVE IS NOT INITIATED WITHIN ONE HOUR, THE UNIT AUTOMATICALLY GOES TO SLEEP TO CONSERVES BATTERY POWER.

13. LET’S GO DIVING

14. AT 5 FT. OF DEPTH, THE DIVE MODE TAKES PRIORITY AND AUTOMATICALLY REPLACES OTHER PROGRAMMING AND DISPLAY MODES.

15. IF ANYTHING IS NOT UP TO THE HIGHEST OPERATING STANDARD, OR IF BATTERY POWER IS INADEQUATE, THE UNIT WILL TURN ITSELF OFF. CHECK YOUR OWNER’S MANUAL FOR BATTERY REPLACEMENT DETAILS.

16. DURING A DIVE, THE FOLLOWING DATA IS AVAILABLE IN A LARGE, EASY TO READ DISPLAY.

17. Water Temperature Maximum Depth (so far this dive) Current Depth Bottom Time (so far this dive) NDC Time Remain (Time you can stay at current depth without Decompression) Ascent Rate (1 bar = 10-19 fpm) Note NDC Legend DIVE MODE

18. A “TWO MINUTE WARNING” IS ISSUED WHEN NO– DECOMPRESSION TIME REACHES 2 MINUTES. THE REMAIN TIME NUMBERS FLASH THE WARNING LEGEND APPEARS AND FLASHES AN AUDIBLE ALARM WILL BE ISSUED

19. 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.

20. 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

21. 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

22. 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

23. IN DECOMPRESSION MODE, THE NDC LEGEND AND VALUES ARE REPLACED BY DECOMPRESSION TIMES & DEC. Deco Stop Time (Alternates between Total Deco Time and time at current Stop) NDC Time Remain (Time you can stay at current depth without Decompression) No-Decompression Time Decompression Time Note NDC Legend Note DEC Legend

24. THE TEMPerature LEGEND AND VALUES ARE REPLACED BY CEILing LEGEND AND VALUES. Deco Ceiling Water Temperature Note TEMP Legend Note CEIL Legend Don’t go above this depth for optimum Decompression

25. IN THIS EXAMPLE, A DECO STOP IS REQUIRED AT 20 FEET FOR 12 MINUTES. Deco Ceiling NOTE THAT THE NDC LEGEND HAS CHANGED TO DEC Deco Stop Time (Alternates between Total Deco Time and time at current Stop)

26. ****************************** PLEASE NOTE THAT DEC TIME AND CEIL DEPTH ARE DISPLAYED ONLY WHEN THE DIVER REQUIRES A DECOMPRESSION STOP. IF THE DIVER DOES NOT REQUIRE A DECOMPRESSION STOP, ONLY NDC TIME AND TEMP WILL BE DISPLAYED. IF THE DEC LEGEND AND VALUES ARE REPLACED WITH THE NDC LEGEND AND VALUES, THEN YOU HAVE FULFILLED YOUR DECOMPRESSION OBLIGATIONS. ******************************

27. THE 10 MINUTE PERIOD FOLLOWING A DIVE IS CALLED THE POST-DIVE INTERVAL. THE SURFACE INTERVAL SCREEN IS VISIBLE. THE SURF LEGEND WILL FLASH UNTIL THE 10 MINUTE POST DIVE INTERVAL HAS PASSED.

28. DISPLAYED DATA Air Temperature Maximum Depth (of the last Dive) Surface Time (Amount of time since last Dive) Bottom Time (of the last Dive) Dive of “Day” (Repetitive Dive Number) Time to Fly (Hours before safely flying) (Post Dive Interval and Surface Interval)

283. SIMPLY BRIDGING CONTACTS 1 AND 2 FOR A COUPLE OF SECONDS WITH YOUR WET FINGER ACTIVATES THE UNIT. A SHORT SERIES OF BEEPS SIGNALS ACTIVATION. Contact #2 Contact #1

284. THE UNIT BEGINS A SELF-TEST TO INSURE THAT ALL SYSTEMS ARE OPERATING CORRECTLY AND ARE “GOOD TO GO.” ALL DISPLAY SEGMENTS ARE VISIBLE AND 5 AUDIBLE SHORT BEEPS ARE PART OF THE SELF- TEST WHEN SUCCESSFULLY COMPLETED.

285. AFTER ACTIVATION AND PRIOR TO DESCENDING BELOW 5 FEET, THE UNIT DISPLAYS TEMPERATURE AND THE SURFACE INTERVAL CLOCK RUNS. ALTITUDE APPEARS IN ASCENT BAR GRAPH Air Temperature Surface Time Barometric Altitude (2500 feet per bar No bars = 0 - 2500 2 bars = 5000 - 7500)

286. UPON COMPLETION OF THE SELF-TEST, THE UNIT ENTERS THE SURFACE INTERVAL MODE. THE ALTERNATE SCREEN CAN BE VIEWED BY TAPPING ON THE FACE OF THE UNIT. MAIN SCREEN ALTERNATE SCREEN

287. IF YOU HAVE RESIDUAL NITROGEN, OR HAVE EXPERIENCED AN ALTITUDE CHANGE, THE SURFACE INTERVAL SCREEN WILL DISPLAY ADDITIONAL INFORMATION. Maximum Depth (of the last dive) Air Temperature Bottom Time (of the last dive) Surface Time (Amount of time since last dive) Time to Fly (Hours before safely flying) Dive of “Day” (Repetitive Dive Number)

288. ALTERNATE SURFACE INTERVAL SCREEN WITH RESIDUAL NITROGEN Battery Voltage (2.9 Volts) OTU Oxygen Toxicity in % CNS Oxygen Toxicity in % PO2 in ATA (Of Blend #1 Set Point)

289. IF A DIVE IS NOT INITIATED WITHIN ONE HOUR, THE UNIT CONSERVES BATTERY POWER AND AUTOMATICALLY GOES TO SLEEP.

290. LET’S GO DIVING

291. AT 5 FT. OF DEPTH, THE DIVE MODE TAKES PRIORITY AND AUTOMATICALLY REPLACES OTHER PROGRAMMING AND DISPLAY MODES.

292. IF ANYTHING IS NOT UP TO THE HIGHEST OPERATING STANDARD, OR IF BATTERY POWER IS INADEQUATE, THE UNIT WILL TURN ITSELF OFF. CHECK YOUR OWNER’S MANUAL FOR BATTERY REPLACEMENT DETAILS.

293. DURING A DIVE, THE FOLLOWING DATA IS AVAILABLE IN A LARGE, EASY TO READ DISPLAY.

294. Water Temperature Current DepthCurrent FO2 Bottom Time (so far this dive) NDC Time Remain (Time you can stay At current depth without Decompression) Ascent Rate (1 bar = 10-19 fpm) MAIN SCREEN VISIBLE DURING A DIVE Note NDC Legend

295. ALTERNATE SCREEN THAT MAY BE VIEWED DURING A DIVE PO2 in ATA (Of Current Blend Set Point) OTU Oxygen Toxicity in % CNS Oxygen Toxicity in % Max Depth (of current dive)

296. A “TWO MINUTE WARNING” IS ISSUED WHEN NO– DECOMPRESSION TIME REACHES 2 MINUTES. THE REMAIN TIME NUMBERS FLASH THE WARNING LEGEND APPEARS AND FLASHES AN AUDIBLE ALARM WILL BE ISSUED

297. 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.

298. 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

299. 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

300. 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

301. IN DECOMPRESSION MODE, THE NDC LEGEND AND VALUES ARE REPLACED BY DECOMPRESSION TIMES, DEC. Deco Stop Time (Alternates between Total Deco Time and time at current Stop) NDC Time Remain (Time you can stay at current depth without Decompression) No-Decompression Time Decompression Time Note NDC Legend Note DEC Legend

302. THE TEMP LEGEND AND VALUES ARE REPLACED BY CEIL LEGEND AND VALUES. Deco Ceiling Water Temperature Note TEMP Legend Note CEIL Legend Don’t go above this depth for optimum Decompression

303. Deco Ceiling IN THIS EXAMPLE, A DECO STOP IS REQUIRED AT 20 FEET FOR 12 MINUTES. NOTE THAT THE NDC LEGEND HAS CHANGED TO DEC Deco Stop Time (Alternates between Total Deco Time and time at current Stop)

304. ALTERNATE SCREEN VIEWABLE DURING DECOMPRESSION PO2 in ATA (Of current Blend Set Point) OTU Oxygen Toxicity in % CNS Oxygen Toxicity in % Max Depth (of current dive) Water Temperature

305. THE 10 MINUTE PERIOD FOLLOWING A DIVE IS CALLED THE POST-DIVE INTERVAL. THE SURFACE INTERVAL SCREEN IS VISIBLE. THE SURF LEGEND WILL FLASH UNTIL THE 10 MINUTE POST DIVE INTERVAL HAS PASSED.

306. DISPLAYED DATA Air Temperature Maximum Depth (of the last Dive) Surface Time (Amount of time since last Dive) Bottom Time (of the last Dive) Dive of “Day” (Repetitive Dive Number) Time to Fly (Hours before safely flying) (Post Dive Interval and Surface Interval)

307. SHOULD ANOTHER DIVE BE STARTED BEFORE THE 10 MINUTE POST DIVE INTERVAL IS COMPLETE, THE DIVE WILL BE CONSIDERED AN EXTENSION OF THE PREVIOUS DIVE. PROGRAMMING IS DISABLED. NOTE: DURING THE 10 MINUTE POST DIVE INTERVAL, TOUCH CONTACT

308. 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.

309. TOUCH CONTACT PROGRAMMING MODE CAN ONLY BE ACCESSED WHEN THE UNIT IS IN THE SURFACE INTERVAL.

310. 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 TEN PROGRAMMING MENUS.
