The procedures that follow must be closely adhered to. Damage due to improper Battery replacement
is not covered by the unit's 2 year warranty.
BATTERY REPLACEMENT
The Battery Compartment should only be opened in a dry and clean environment with extreme care taken to prevent the en-
trance 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 in the module,
DO NOT use the Pro Plus 3 until it receives proper service by an Authorized Oceanic Dealer, or the Oceanic factory.
Data Retention
When the battery is removed, settings* and calculations for repetitive dives are retained in volatile memory until a new battery is
installed.
*Date will have to be set, Time may require adjustment for the time duration that the battery remains out of the unit.
Battery Removal
Examine the Case Back to locate the Battery Cover (Fig. 81a):
• Remove the 4 screws that secure the Battery Cover to the Housing by turning counter clockwise.
• Lift the Cover up and away from the Housing.
• Lift the Battery, positive (+) end first, out of the Battery Compartment.
• Remove the Battery Cover O-ring and inspect it for any signs of deterioration or deformity. DO NOT use tools to remove the
O-ring.
• O-ring replacement is highly recommended to ensure proper sealing.
• Closely examine the sealing surfaces of the Battery Cover and Housing for any signs of damage that might prevent proper
sealing. If found, return the Pro Plus 3 to an Authorized Oceanic Dealer, and DO NOT attempt to use it until it has received
factory service.
• Closely examine the inside of the Battery Compartment for any signs of corrosion indicating entrance of moisture into the unit.
• If corrosion is found, return the Pro Plus 3 to an Authorized Oceanic Dealer, and DO NOT attempt to use it until it has re-
ceived factory service.
Moisture in the Battery Compartment
• 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 the 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').
• Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
• Inspect the Buttons, Lens, and Housing to ensure they are not cracked or damaged.
Battery Installation
• Replace the Cover 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 Cover O-ring with silicone grease and place it on the beveled outer edge of the Battery Compart-
ment (Fig. 82a). Ensure that it is evenly seated.
• Place a new 3 volt, CR2, .75 AHr, Lithium Battery (Duracell model DL-CR2 or equivalent) negative end first into the Battery
Compartment with the negative end toward the spring (Fig. 83a).
Battery Hatch Installation
• Ensure that the Battery is properly oriented and the Cover O-ring is evenly seated.
• Carefully place the Battery Cover into position so that it seats on top of the O-ring, and while holding it in place, secure it
with the 4 screws by turning them clockwise. DO NOT attempt to use any other screws.
• Carefully tighten the screws by alternately turning them each one turn at a time (Fig. 84). Turn the upper left one (a), then the
lower right (b), then the lower left (c), then the upper right (d).
• Repeat the sequence until all of the screws are evenly secure. The outer surface of the Battery Cover should be flush with the
outer surface of the Housing. DO NOT overtighten.
Inspection
• Activate the unit and watch carefully as it performs a full diagnostic and battery check, and enters Surface Mode. Observe
the LCD display to ensure it is consistently clear and sharp in contrast throughout the screen.
• If any portions of the display are missing or appear dim, or if a Low Battery Condition is indicated, return your Pro Plus 3 to
an Authorized Oceanic Dealer for a complete evaluation before attempting to use it.
