To remove the DIN to USA Converter:
 While holding the DIN connector wheel firmly, turn the DIN to USA Con-
verter counter clockwise off the threads of the first stage DIN connector.
DO NOT use tools to remove.
 Place the protector cap on the threads of the regulator DIN connector
wheel.
ENVIRONMENTAL PROTECTION KIT
By function of design, the inner components of Oceanic diaphragm type regula-
tor first stages (i.e., CDx, DX4) are isolated from the ambient environment.
However, the outer side of the diaphragm and the diaphragm spring, located in-
side the cavity at the hex opening end, will be subjected to environmental con-
ditions.
Oceanic recommends installation of an Environmental Kit on diaphragm type
First Stages (i.e., CDx) subjected to environmental conditions in which debris, or
sediment, or ice, or salt crystals might form in the spring cavity. The kit is a
unique dry seal system that uses no messy grease or chemicals.
Most DX4 first stages are shipped from the factory with the Environmental Kit in-
stalled. If your DX4 (or other model) is not configured with an Environmental Kit,
one can easily be installed by your Authorized Oceanic Dealer.
WARNING: Installation of an Environmental Kit must be per-
formed by an Authorized Oceanic Dealer. Improper installation
may cause first stage failure while underwater resulting in serious
injury or death.
REGULATOR SECOND STAGES
WARNING: Even if your First Stage is properly prepared for use
in harsh environmental conditions, only proper training will pro-
tect your Second Stage from the effects of the environment.
FEATURES AND OPERATION
The Second Stage of the regulator assembly receives breathing gas at an inter-
mediate pressure of approximately 140 psi from the first stage and delivers it to
you at ambient pressure during inhalation. When you stop inhaling, it then
shuts off the flow of breathing gas and provides a path for exhaled gas.
All Second Stage regulators have a level of sensitivity that can result in excess
breathing gas being expelled when the Second Stage is not in your mouth while
in the water. When this occurs, it is usually during entry or when on the surface.
This condition, refered to as free-flow, can usually be stopped by turning the
Second Stage so the mouthpiece is pointing down and the purge button is point-
ing up. (See Omega II for an exception to this general feature.)
