OCi OPERATING MANUAL
© 2002 Design, 2013 Doc. No. 12-5335-r01 (6/27/13)
Inspection
• 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.
WARNING: If damage or corrosion is found, return your OCi to an Authorized Oceanic Dealer, and DO
NOT attempt to use it until it has received factory prescribed service.
• Remove the cover O-ring by squeezing the sides (Fig. 181a). Discard, and do not attempt to reuse it.
> It is located around the top rim of the cover.
> DO NOT use tools to remove the O-ring.
> To ensure proper sealing, O-ring replacement is required each time the Battery is replaced.
Battery Installation
• Very lightly lubricate the new O-ring with silicone grease and place it on the top rim of the cover.
• Place a new 3 volt type CR2450 Lithium Battery, negative side down into the Battery cavity and ensure that it is evenly
positioned (Fig. 182).
• Carefully position the Battery Cover over the battery compartment. Use the OCi logo as a guide for top/bottom. Also,
small symbols have been engraved on the top of the Cover and strap to serve as a guide for proper alignment (Fig. 183a).
• While ensuring that the cover and back of the case are properly aligned, firmly press them evenly and completely together.
• While holding the Battery Cover firmly in position agaonst the back of the case (Fig. 184), insert the (4) retaining screws
and tighten them until secure by turning them clockwise with a small flat tip 3mm screw driver. DO NOT over tighten.
Testing
> Activate the unit and ensure that the LCD is clear and sharp in contrast. If any portions are missing or appear dim, or if a
Low Battery condition is indicated, return the OCi to an Authorized Oceanic Dealer for evaluation before use.
> During 24 hours after completion of a dive, the graphics SEL and DATA with selections SAVE ? and CLEAR ? will be
displayed (Fig. 185) giving you the option to retain or delete Ni-O2 calculations for repetitive dives.
• A (< 2 sec) to toggle between SAVE and CLEAR
• S (< 2 sec) to save the selection
> Graphics DATA SAVED (or CLEARED) with CAL COMPASS appear for 3 seconds (Fig. 186), then operation reverts to the
Compass CAL screen.
> Calibrate the Compass.
> Verify all set points prior to diving.

ALTITUDE SENSING AND ADJUSTMENT
Prior to the first dive of a series of repetitive dives, Altitude (i.e., ambient pressure) is measured upon activation of Dive Surface
Mode and every 15 minutes until a dive is made or operation reverts to Watch Mode.
> While it is operating in Watch modes after a dive, measurements are taken every 15 minutes during the 24 hour period
after surfacing.
> 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 OCi 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 OCi will not function as a Dive Computer above 14,000 feet (4,270 meters).
