BUD OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5259-r01 (7/21/11)
WARNING: If damage, moisture, or corrosion is found, return your BUD to an Authorized Oceanic Dealer, and
DO NOT attempt to use it until it has received factory prescribed service.
Battery Installation
• Slide a new 3 volt type CR2430 Lithium Battery, negative side down into the Battery Compartment. Slide it in from the left
side (Fig. 48) and ensure that it slides under the contact clip on the lower/right rim of the cavity.
• Lightly lubricate the new Cover O-ring* with silicone grease and place it on the inner rim of the Battery Cover. Ensure that it
is evenly seated (Fig. 49).
*The 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.
• Carefully place the Battery Cover (with O-ring) into position on the rim of the Battery Compartment, then press it evenly and
completely down into place.
• Maintain the Battery Cover securely in place and turn it counter clockwise 10 degrees using the special Battery Cover tool
(Fig. 50A), or by pushing the lower portion to the right while pushing the upper portion to the left (Fig. 50B).
Testing
• Observe the LCD display to ensure it is consistently clear and sharp in contrast throughout the screen.
• Set the Date and Time.
• Verify all Set Points prior to diving.
If any portions of the display are missing or appear dim, or if a Low Battery Condition is indicated, return
your BUD to an Authorized Oceanic Dealer for a complete evaluation before attempting to use it.
ALTITUDE SENSING AND ADJUSTMENT
Altitude (i.e., ambient pressure) is measured upon activation and 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 BUD automatically adjusts to these conditions providing
corrected Depth, and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).
> At Sea Level, calculations are based upon an Altitude of 6,000 feet.
> 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).
> The BUD will not function as a Dive Computer above 14,000 feet (4,270 meters).
