Inspection (continued) -
• Closely examine the inside of the Battery Compartment(s) for any signs of corrosion
indicating entrance of moisture into the unit.
• If corrosion is found, return the VT Pro to an Authorized Oceanic Dealer, and DO NOT
attempt to use it until it has received factory service.
• If moisture is found, it is best to have the unit inspected and cleaned by an Authorized
Oceanic Dealer.
• If it is necessary to clean the Battery Compartment, flush it and all components with a
solution of 50% white vinegar and 50% fresh water. Rinse with fresh water, and allow
to dry overnight, or blow dry with a hair dryer (set at 'no heat').
Display Module Battery Installation
• Slide a new 3 volt type CR2450 Lithium Battery, negative (-) side down into the Battery
Cavity. Slide it in from the right side and ensure that it slides under the contact clip on
the left rim of the cavity.
• Orient the Retaining Bar across the lower portion of the Battery and carefully push it
down into position.
• Replace the Hatch O-ring with a new one. This 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.
• Lightly lubricate the
new
Hatch O-ring with silicone grease
and place it on the inner rim of the Battery Hatch. Ensure
that it is evenly seated.
• Slide the Hatch Ring, top portion first (small opening), onto
your thumb (Fig. 108).
