Frequently Asked Questions - Ultra SD OCEANIC
How do I change the battery in my Oceanic Ultra SD?
Use a small screwdriver to open the battery compartment. Remove the old CR2450 battery and replace with a new one, ensuring the + side faces up. Check the o-ring for damage and lubricate if necessary before closing.
What types of diving modes does the Ultra SD support?
The Ultra SD supports Air, Nitrox (up to 100% O2), Gauge, and Free Dive modes. You can switch modes via the menu.
How do I set the nitrox mix on my dive computer?
In Nitrox mode, press and hold the button to enter the gas setup. Use the button to scroll to the desired O2 percentage (21-100%) and press to confirm. The computer will automatically adjust no-decompression limits.
Why is my Oceanic Ultra SD beeping during a dive?
Beeping indicates an alarm. Common alarms include depth alarm (exceeding user-set depth), ascent rate too fast, decompression obligation, or high oxygen exposure. Check the display for the specific warning.
How do I download dive logs from the Ultra SD?
Use the optional Oceanic infrared interface and compatible software. Align the infrared port of the computer with the interface, start the software, and follow the prompts to transfer logs.
What is the maximum depth the Ultra SD can display?
The maximum displayed depth is 330 feet (100 meters). The computer is tested to this depth, but actual safe diving limits depend on your training and gas mix.
Can I use the Ultra SD for freediving?
Yes, the Ultra SD includes a Free Dive mode that tracks your depth, dive time, surface interval, and provides bottom time alerts. It does not calculate no-decompression limits in this mode.
How often should I replace the o-ring on my dive computer?
Inspect the o-ring every time you change the battery. If it appears dry, cracked, or deformed, replace it. Otherwise, replace it at least once a year or after 100 dives.
The display on my Ultra SD is faint. What should I do?
First, check the battery level. A low battery can cause a dim display. If the battery is new, try activating the backlight by pressing the button. If still faint, contact Oceanic service for display issues.
How do I reset the Ultra SD to factory settings?
With the unit off, press and hold the button for about 10 seconds until the display shows all segments. Release the button; the computer will restart in setup mode. Use the menu to reset to defaults (caution: this erases all settings).
