VTX OPERATING MANUAL
© 2002 Design, 2014 Doc. No. 12-5382-r01 (10/24/14)
ALTITUDE SENSING AND ADJUSTMENT
Prior to the first dive of a series of repetitive dives, Altitude (i.e., ambient pressure) is measured upon activation then every 15
minutes until a dive is made.
> Measurements are only taken when the unit is dry.
> Two readings are taken, the second reading 5 seconds after the first. The readings must be within 1 foot (30 cm) of each
other to record that ambient pressure as the current Altitude.
> No adjustments are made during any time that the Wet Contacts are bridged.
When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270 meters), the VTX automatically adjusts to these
conditions providing corrected Depth, and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).
At an elevation of 3,001 feet (916 meters), Depth calibration automatically changes from feet of seawater to feet of fresh water.
This is the first adjustment to the algorithm.
When the Conservative Factor feature is set On, NDLs are calculated based upon the next higher 3,000 foot (915 meter) Alti-
tude. All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times for 14,000
feet (4,270 meters). At Sea Level, calculations are based upon an Altitude of 6,000 feet.
The VTX will not function above 14,000 feet (4,270 meters).

CARE AND CLEANING
Protect your unit from shock, excessive temperatures, exposure to chemicals, and tampering. Protect the lens against scratches
with a Instrument Lens Protector. Small scratches will naturally disappear underwater.
• Soak and rinse the VTX in fresh water at the end of each day of diving, and check to ensure that the areas around the low
pressure (depth) sensor (Fig. 95a), data port (Fig. 95b), and buttons are free of debris or obstructions. Soak and rinse the
regulator with the transmitter attached.
• To dissolve salt crystals, use lukewarm water or a slightly acidic bath (50% white vinegar/50% fresh water). After removal
from the bath, place the VTX and the regulator assembly with transmitter under gently running water and towel dry before
storing.
• Transport your VTX system cool, dry, and protected.
INSPECTIONS AND SERVICE
Your VTX should be inspected annually by an Authorized Oceanic Dealer who will perform a factory prescribed function check
and inspection for damage or wear. To keep the 2 year limited warranty in effect, this inspection must be completed one year
after purchase (+/- 30 days).
Oceanic recommends that you continue to have an inspection performed every year to ensure it is working properly. The costs of
annual inspections are not covered under the terms of the 2 year limited warranty.
To Obtain Service:
Take your VTX to an Authorized Oceanic Dealer.
To return your VTX to Oceanic:
• Record all data in the viewable Log and/or download the data in memory. All data will be erased during factory service.
• Package it using a protective cushioning material.
• Include a legible note stating the specific reason for return, your name, address, daytime phone number, serial number(s),
and a copy of your original sales receipt and Warranty Registration Card.
• Send freight prepaid and insured using a traceable method to the nearest Oceanic Regional Facility, or to Oceanic USA.
• If shipping to Oceanic USA, obtain an RA (Return Authorization) number by contacting Oceanic at 510-562-0500 x761 or
