TRANSMITTER BATTERY REPLACEMENT
Battery Removal
Locate the Battery Cover on the end of the housing:
Apply a coin to the recessed slot of the Cover and turn it counter clockwise out of the housing (Fig. 101).
Remove the Battery and discard it according to local regulations governing disposal of Lithium batteries.
Battery Installation
• Lightly lubricate the new Battery Cover O-ring with silicone grease and install it onto the Battery Cover. DO NOT roll the
O-ring over the Threads, instead stretch it slightly to work it down over the slotted end of the Cover into the groove at the base
of the threads (Fig. 102).
• The O-ring must be a genuine Oceanic part that can be purchased from an Authorized Oceanic Dealer.
Use of any other O-ring will void the warranty.
• Insert a new CR2 Lithium 3 Volt Battery (Duracell or equivalent) positive (+) side first into the Battery compartment with the
negative end facing out (Fig. 103).
• Ensure that the Battery is properly installed and the Cover O-ring is evenly seated around the Cover.
• Carefully place the Cover (with spring) into the housing and turn clockwise slowly by hand to ensure proper threading.
• Apply a coin and tighten the Cover by turning it clockwise until secure (Fig. 104). The outer surface of the Cover should be
flush with the outer surface of the housing.
TRANSMITTER INSTALLATION ON A REGULATOR
• Remove the existing pressure gauge and high pressure hose, or the high pressure port plug from the port marked HP using
the proper size hex key.
• Lightly lubricate the o-ring and threads of the Transmitter fitting with a halocarbon based lubricant such as Christo-Lube
MCG111.
• Thread the Transmitter clockwise by hand into the regulator's HP port (Fig. 105) and tighten until secure with an appropriate
sized open end wrench.
• Attach the regulator First Stage to a full scuba tank and pressurize by slowly opening the tank valve, listening for any
indication of air leaking around the fitting.
• If air leakage is present, DO NOT use, take the complete regulator assembly to an Authorized Oceanic Dealer for inspection
and service.

When packaged and shipped from the factory, Oceanic Transmitters are rated for use with compressed Air and/or nitrogen-
oxygen (Nitrox) breathing gas mixtures containing up to 99% O2 by volume and with 100% O2.

WARNINGS
Decompression diving, or diving deeper than 130 FT (39 M), will greatly increase your risk of decompression sickness.
Decompression diving is inherently hazardous and greatly increases your risk of decompression sickness, even when performed
according to the dive computer's calculations.
Using an VTX is no guarantee of avoiding decompression sickness.
The VTX enters Violation Mode when a situation exceeds its capacity to predict an ascent procedure. These dives represent
gross excursions into decompression that are beyond the boundaries and spirit of the VTX's design. If you are following these
dive profiles, Oceanic advises that you should not use an VTX.
If you exceed certain limits, the VTX will not be able to help you get safely back to the surface. These situations exceed tested
limits and can result in loss of some functions for 24 hours after the dive in which a violation occurred.
