This Manual is intended for use with the
CO
with and without the
Nitrox functions being enabled. Manual sections that apply to the Nitrox
capabilities are in Italic type.
PRODUCT INTRODUCTION:
The
CO
is quite simple to use and operate,
but underneath that simplicity lies a significant level of sophistication. To get the safest
and most effective use of this instrument, it is important that the user fully understand
the product. Please read and understand this entire manual and know the principles
and practices of safe diving before using this device.
If you are using the
CO
, With the Nitrox functions enabled, the diver specifically acknowledges
that he has been adequately and thoroughly trained and certified to engage in Nitrox
diving by a professional, competent, recognized training agency.
USER & ENVIRONMENTAL ADAPTATION:
The
CO
is one of the new
breed of Dive Computers that adapts its algorithm to the user’s diving environment and
style as originally pioneered by COCHRAN. All of COCHRAN’s newer dive computers
incorporate this capability. The factors that are used for this “Adaptation” in the
CO
are:
Water
Temperature
Salt/Fresh
Water
Compensation
Microbubble Altitude
Acclimatization
User
Conservatism

WATER TEMPERATURE:
Diving in cold water can lead to a lower diver core and skin
temperature which can affect the gas exchange rate of the body’s tissues. The
CO
progressively makes its nitrogen algorithms more conservative as the
water temperature declines below 25 degrees C. Above this water temperature, there is
no temperature compensation. If the diver is wearing an insulated dry suit and is
relatively warm even in cold water, this temperature compensation factor may be turned
off at the divers discretion using the

PC software. (See later

There are several theories regarding the exact method by which a
