Quick Start Guide for operation
Diving is a complex sport and many different situations may occur. Your Cochran EMC-14 is designed to compute and display data for any dive situation that you are likely to encounter.  This Quick Start Guide, however, covers normal conditions only;  please see the owner's manual for complete explanation of other operating modes.

2. There are three metal contacts on the front of the EMC-14 Dive Computer; moisten your finger and place it over contact #1 and contact #2 for a few seconds to POWER UP the Computer.

Contact #2

3. All display segments are visible as part of the SELF-TEST.
Immediately after Power Up, the EMC-14 begins a SELF-TEST to insure that all systems are operating correctly.
All display segments are visible as part of the SELF-TEST.

4. Altitude (2500 feet per bar) Surface Time since power-up
Immediately after the self-test, the EMC-14 enters the SURFACE MODE, and remains in this mode until it descends below 5 feet.

Altitude (2500 feet per bar)
No bars = 0 to 2500 ft.
2 bars = 5000 to 7500 ft.

If a dive is not initiated within one hour, the EMC-14 automatically powers down to conserve battery power.

5. Current CNS Oxygen Toxicity value Alternate Screen showing Time
When the EMC-14 is in the SURFACE MODE it will alternate between the Primary and Alternate screens ever 8 seconds.

12. The WARNING LEGEND appears and flashes
A “TWO MINUTE WARNING” is issued when no-decompression time reaches 2 minutes
The WARNING LEGEND appears and flashes
The REMAIN TIME numbers flash
WRONG SLIDE

13. Staying at the same depth, or going deeper after the 2 minute warning expires, will cause the EMC-14 to enter the DECOMPRESSION MODE.
If you plan to perform decompression dives, we recommend that you have adequate training.

14. DECOMPRESSION MODE
Divers should be familiar with the DECOMPRESSION MODE for the EMC-14 Dive Computer, even if they never intend to dive in a manner that will cause the computer to enter this mode.
The DECOMPRESSION MODE is explained in the EMC-14 Tutorial presentation.
IMPORTANT: Please refer to the instruction manual for detailed information on the operation of your COCHRAN EMC-14

15. HAPPY DIVING, HAVE FUN, AND MOST IMPORTANTLY, BE SAFE!
