COCHRAN EMC-14

DIVE COMPUTER

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.

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.

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.

Immediately after the self-test, the EMC-14 enters the SURFACE MODE, and remains in this mode until it

descends below 5 feet.

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.

The WARNING LEGEND appears and flashes

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.

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.
