TRANSMITTER 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. 141).

• Remove the Battery and discard it according to local regulations governing disposal of Lithium batteries.

TRANSMITTER 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. 142).

• 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.

• Place a new 3 volt CR2 Lithium Battery (Duracell model DL-CR2 or equivalent) positive (+) side down into the Battery

compartment with the negative end facing up/out (Fig. 143).

• Ensure that the Battery is properly oriented 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 until secure. The outer surface of the Battery Cover should be ﬂush with the outer surface of the

housing (Fig. 144).

INSTALLING A TRANSMITTER 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. 145) 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-
