The logbook will store up to 600 hours of detailed dive profiles in memory. The lithium ion battery is built into the case. It can be quickly recharged with the AC charger or slow charged by The Algorithm used in Cobalt is the Recreational RGBM plugging into the USB port of any PC. It will provide 40-50 (Reduced Gradient Bubble Model) created exclusively hours of dive time between charges and many months of for Atomic Aquatics by Dr. Bruce Wienke. The RGBM is standby power.

No computer is a substitute for demands of which may exceed your and the computer’s proper training. limitations. Exceeding these limitations may cause serious decompression sickness or other injuries, including death. WARNING WARNING Read this manual carefully before diving. It is imperative that you fully understand the functions and displays of There is always a risk of decompression sickness on any the dive computer and that you are both proficient in and dive regardless of whether you follow dive tables or a dive familiar with their use prior to diving. The improper use of computer. In order to lessen the risk of decompression this computer may lead to serious injury or death. sickness, you should always dive well within the exposure limits provided by this computer. If you experience WARNING symptoms of decompression sickness, seek medical attention immediately! The gas mixes for enriched air nitrox will not accept fractional percentage values of oxygen concentration. WARNING You should always round down when editing a gas mix in the Gas/Tank Settings Menu. For example, a gas mix of Before diving, make sure the battery is charged to allow 32.6% oxygen should be entered as 32%. Rounding up diving time well in excess of your planned dive. Atomic will affect decompression calculations which could lead to recommends that you not dive with a battery status of less decompression sickness. than 25%. 6 Warnings Warnings WARNING WARNING Do not dive without activating the computer. Before You should never dive with enriched air nitrox unless entering the water, you should ensure that the display you have personally verified the oxygen percentage and is functioning properly, that you have reviewed the entered the proper value into the Gas/Tank Settings information in the PreDive Check menu, and have selected menu of your dive computer. Failing to verify the oxygen the Ready to Dive option. If you feel the computer is not percentage or entering the wrong value could subject you functioning properly or that the information contained in to decompression sickness. the display is incorrect, do not dive. WARNING WARNING Always dive with back-up instruments. Even when using You should never share or trade your dive computer a dive computer, you should always carry a submersible during a dive. Your computer gathers information pressure gauge, a depth gauge, and a watch or other during a dive that is applicable only to you. If you timing device. share or trade your computer with another diver, your decompression limits will be inaccurate which may WARNING cause decompression sickness. You should never fly after diving until you verify that the No Fly Time reads 0:00. Flying during the No Fly Time can result in decompression sickness. 7 Compass Recalibration Procedure Save and use the insert tray from the Cobalt packaging to aid in re-calibrating your Over computer’s compass to your current location. Pressure Plug USB/ DO NOT Charger Fold legs into triangles TAMPER Terminal and place firmly into WITH Socket calibration tray. and Wet Step 1 Place computer firmly Contacts into tray. Place tray onto non- metallic table surface and AC Charger USB away from any metal or Cable magnetic objects. Align edge of tray to edge of table or reference line. Turn on computer, go to USB AC Step 2 Main Menu, Settings, Calibrate Compass. USB Follow the instructions Side AC Charger on the display to enter Cable readings with the computer in the three steps shown on the left. (Flip Adapter AC Side over for USB) Exit the calibration screen. USB/Charger Adapter Slot for Step 3 USB Charger 8 Battery Your Cobalt uses a rechargeable Lithium Ion battery that is sealed inside the case. Check the battery level (the charge level is displayed in the Main Menu) and fully charge the battery before the first use and occasionally afterwards. Best battery life will come from keeping the battery charged. A full charge will last for approximately 40-50 hours of dive time (depending mostly on screen brightness settings). A battery warning indicator will appear on the dive display if the battery charge is below 15%. This charge level should still be sufficient to complete several average dives. On the surface, The Cobalt display will automatically go dark after 5 minutes to conserve power. Press the SELECT button to wake the display. The Cobalt is never really turned completely off, but has various sensing modes depending if the Cobalt is wet, or in the "Ready to Dive" screen. It will wake automatically if it is submerged in water and will start a dive if it senses pressure. However, we strongly recommend that you use the Pre-Dive Check function to ensure your settings are correct, and manually select the "Ready to Dive" screen before entering the water. If you allow the battery to completely discharge, you will need to reset the time and date (page 14). On powering up again, the Cobalt will return to the time as of the end of the last dive. Your logged dives, decompression status, and other personal information are preserved and will not be affected by loss of power. The battery will last several years of normal use before gradually diminishing in capacity, and can be replaced by the factory or an authorized Atomic Aquatics Dealer. Charger set-up The Cobalt can be charged with either the AC quick charger (about 2 hours to full charge) or from a USB cable connected to a computer (about half the speed of AC charging). The AC charger will automatically select 110 or 220v AC. Plug the end of the charger cable into the charger/USB adapter. Plug the charger into an AC outlet and the adapter into the bottom of the Cobalt. The adapter has 2 sides, make sure you insert it into the side nearest the charge method you selected (AC charger or USB). Confirm charging by going to the main menu. The display will say “charging”. 9 Connecting Cobalt to the High Pressure Quick Disconnect Figure 1 Figure 2 Figure 3 High pressure connector Unscrew the Lock ring Push on and Screw lock ring until turn to the lock ring ring is flush right 1/4 turn up against with end of High pressure to lock console base disconnect hose and to prevent quick disconnect accidental disassembly 10
