Overview
The Field Programmer is designed to be used with the NEMESIS™ IIa NITROX Dive
Computer. IT IS NOT COMPATIBLE WITH PREVIOUS NEMESIS SERIES. This device
allows the user to program into the dive computer a value representing the percentage
of oxygen contained in a given breathing gas mix for all three mixes, the cylinder size
which is used in making Workload computations, an added degree of conservatism
from 0 to 50%, and a maximum depth alarm.
WARNING: The NEMESIS™ IIa NITROX Dive Computer and the Field Programmer are
to be used only by divers trained and certified in the use of Nitrox breathing gas mixes
by an accredited certifying agency.
NOTE: The Field Programmer is NOT waterproof.
Installation
1. To install, orient the probe of the Field Programmer so that the wire running
