Warnings WARNING Before diving, you should have the proper training from a qualified instructor and obtain a certification from a qualified training agency. No computer is a substitute for proper training. WARNING This computer is for recreational use only. The computer is not designed for commercial or professional diving, the demands of which may exceed your and the computer’s limitations. Exceeding these limitations may cause serious decompression sickness or other injuries, including death.
Warnings WARNING Do not dive without activating the computer. Before entering the water, you should ensure that the display is functioning properly, that you have reviewed the information in the PreDive Check menu, and have selected the Ready to Dive option. If you feel the computer is not functioning properly or that the information contained in the display is incorrect, do not dive.
Compass Recalibration Procedure Turn on the computer, go to Main Menu, Settings, Calibrate Compass. Step 1. Orient the Cobalt along an estimated North-South direction.

Compass calibration – The compass should be re-calibrated to your particular locale. Go to Settings/Calibrate and follow the screen prompts. See page 8 for more details.
Main Menu Ready to Dive The top section of the dive display changes when a safety, deep, or decompression stop is required. The next required stop depth and time (min:sec) are shown in the box at the top left of the screen. No Deco Time is moved to the upper right of the screen. Safety Stops are always recommended and indicated in a green box that will appear when nearing the surface or after any deep or safety stops have cleared. Deep stops are indicated in a blue box as the stops become required.
Main Menu Ready to Dive If you plan on switching to an alternate mix while diving, you must first program at least one Gas Switch Alert in the Gas Switch Alert screen. Cobalt will use planned gas switches when calculating no-deco times and surfacing schedules. Switching away from your primary gas mix will disable the gas time remaining calculations. This and the tank pressure reading will be shown in a grayed text color whenever you are not using the primary mix.
Main Menu In decompression diving, the display further changes with the Ascent time replacing the No-Deco time in the upper right corner of the display. Deco Stops are indicated in an orange window. Ascent time is based upon a direct ascent at a rate of 30' per minute including all decompression, deep and safety stops.
Main Menu Ready to Dive When you reach a depth within 5' (1.5m) of the stop depth, the label will change from Deco Stop to At Stop and the time will begin counting down towards zero. Decompression: At Stop To reach your decompression stop, ascend at a constant 30 foot per minute rate to the depth indicated in the Deco Stop window. When you are within 5 ft (1.5m) of the indicated depth, the Deco Stop label will be replaced by the At Stop label. The timer will count down to zero as you complete the stop.
Main Menu Ready to Dive Ascending more than 5 feet above the stop depth will trigger a GO DOWN! alert. Warning! Descend immediately to indicated stop depth! Decompression: Above Stop Alert If you violate the stop depth (ceiling) the timer will stop counting down until you descend to within the stop depth range. Descend immediately to the indicated stop depth! Immediate descent will resume the countdown timer and the schedule. Delay will create a decompression violation.
If you see these warnings flash back and forth, descend immediately to the indicated stop depth! If you see this warning stop diving and seek medical attention! This warning will remain in the dive screen if you attempt to dive again.
Ascent Rate Alert (Slow your ascent!) Flashing Depth Alert (Ascend to shallower depth!) Flashing Low Air or Gas Time Alert (Ascend to shallower depth!) Flashing PO2 or CNS Alerts. PO2-(Ascend to shallower depth!) CNS- Alerts you if you reach 80% or more (Ascend and terminate dive!) User set Low Gas and Max Depth Alerts can be both visual and audible (ON), visual only (SILENT), or (OFF). All others are both visual and audible and cannot be turned off.
