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 VT 4.0 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. 133a), PC interface data port (Fig. 133b), 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 VT 4.0 and the regulator assembly with transmitter under gently running water and towel dry before 

storing.  

•  Transport your VT 4.0 system cool, dry, and protected.

INSPECTIONS AND SERVICE

Your VT 4.0 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, or inspections relating to water tight integrity, are not covered under the terms of the 2 year limited warranty.

BATTERY REPLACEMENT

The procedures that follow must be closely adhered to to avoid entrance of water into the unit.  Dam-

age due to improper Battery replacement (or subsequent leakage of moisture into the unit) is not 

covered by the VT 4.0's 2 year warranty.

When replacing the Battery in the VT 4.0, it is recommended that you also consider 

replacing the Battery(s) in the Transmitter(s) to be used, and vice-versa. 

The Battery Compartment should only be opened in a dry and clean environment with extreme care taken to prevent the entrance 

of moisture or dust.

As an additional precautionary measure to prevent formation of moisture in the Battery Compartment, it is recommended that the 

Battery be changed in an environment equivalent to the local outdoor temperature and humidity (e.g., do not change the Battery 

in an air conditioned environment then take it outside during a hot sunny day).

Inspect the Buttons, Lens, and Housing to ensure they are not cracked or damaged.  If there is any sign of moisture inside the unit, 

DO NOT attempt to use it for diving until it receives proper service by the Oceanic factory or an Authorized Regional Facility.

Data Retention

When the battery is removed, settings* and calculations for repetitive dives are retained in volatile memory until a new battery is 

installed.  You will have the choice of saving or deleting the data (see page xx).

*Date will have to be set, Time may require adjustment for the time duration that the battery remains out of the unit.

Battery Cover Removal

•  Locate the Battery Compartment on the back of the module.

•  While applying steady inward pressure on the clear Battery Cover, rotate the Cover Ring clockwise 10 degrees by pressing 

on the upper/right arm of the Ring with a small blade screwdriver (Fig. 134A). 

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, then push and turn (Fig. 134B).

•  Lift the Cover Ring up and away from the Housing. 

•  Remove the clear Battery Cover.
