Page 7 The programs within the VT3 simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The VT3 dive computer model is Still, using the VT3, just as using the based upon the latest research and experiments in decompression theory.
Page 8 Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician. Warning: Changes or modifications to this unit not expressly approved by Oceanic/2002 Design could void the user's authority to operate the equipment.
Page 9 WARNING: Prior to diving with the VT3, you must also read and understand the Oceanic Dive Computer Safety and Reference Manual, Doc. No. 12-2262, which provides Important Warnings and Safety Recommendations as well as general product information. INTRODUCTION GENERAL FEATURES AND DISPLAYS...

BATTERY REPLACEMENT NOTE: The procedures that follow must be closely adhered to. Dam- age due to improper Battery replacement is not covered by the VT3's 2 year warranty. When replacing the Battery in the VT3, it is recommended that you also replace the Battery(s) in the Transmitter(s), and vice-versa.
Page 143 VT3 Battery Hatch Removal NOTE: If available, an adjustable face spanner tool or pointed pliers can be used by inserting the tips of the tool in the small holes in the Ring (Fig. 126). VT3 Battery Removal NOTE: DO NOT allow a metal object to short circuit the top of the Battery which is positive (+) to the negative ( - ) contact of the Compartment.
Page 144 Transmitter Battery Removal VT3 and Transmitter Inspection WARNING: If damage or corrosion is found, return your VT3 system to an Authorized Oce- anic Dealer, and DO NOT attempt to use it until it has received factory prescribed service.
