A300/A300 XT OPERATING MANUAL OVERVIEW The A300 model features FREE Dive mode as well as NORM, TECH, and GAUG modes. The A300xt model features a Tank Pressure alarm (actuated by an reed switch) for an analog pressure gauge mounted in the same console as the dive computer module. NORM mode is intended for the casual diver who plans to use a single gas and does not yet wish to configure the numerous settings and alarms, many are factory set at predetermined fixed values.
A300/A300 XT OPERATING MANUAL AUDIBLE ALARM While operating in NOR, TEC, or GAU mode, the Audible will emit 1 beep per second for 10 seconds when alarms strike, unless it is set Off. During that time, the Audible can be acknowledged and silenced by pressing the S button (less than 2 seconds). An LED Warning Light, on the housing, is synchronized with the Audible and flashes as the Audible sounds. It will turn Off when the Alarm is silenced.
A300/A300 XT OPERATING MANUAL POWER SUPPLY • Battery >> (1) 3 vdc, CR2450, Lithium. • Shelf life >> up to 5 years. • Use life >> 100 dive hours if (1) 1 hour dive per dive day up to 300 dive hours if (3) 1 hour dives per dive day. • Use life >> 300 dive hours if (2) 1 hour dives per dive day. • Replacement >> by user (annual recommended).

A300/A300 XT OPERATING MANUAL DIVE MODE FEATURES © 2002 Design, 2012 21 Doc. No.
A300/A300 XT OPERATING MANUAL WET ACTIVATION OF DIVE MODE The unit is configured with contacts that will automatically activate Dive Mode when the space between the contacts is bridged by a conductive material (immersed in water) and it senses a Depth of 5 FT (1.5 M). The contacts are the metal pins of the PC Interface Data Port and the stems of the buttons. SMARTGLO® BACKLIGHT The unit is configured with a sensor that measures the intensity of ambient light.
A300/A300 XT OPERATING MANUAL CONSERVATIVE FACTOR (CF) When the CF is set On, the NDLs which are based on the algorithm selected and used for Ni/O2 calculations and displays relating to Plan and DTR, will be reduced to the values available at the altitude level that is 3,000 feet (915 meters) higher. Refer to the NDL charts in the back of this manual.
A300/A300 XT OPERATING MANUAL O2 Time Remaining (OTR) During Nitrox operation, O2 accumulation during a dive, or 24 hour period, is displayed on an Alternate screen as a percent of O2 saturation allowed per dive or per day (Fig. 60a). Max allowed is 300 OTU (= 100%). a When time remaining before reaching the O2 limit becomes less than NDC, calculations for that Depth will be controlled by O2 and OTR will be displayed as DTR on the Dive Main (Fig. 61a).

A300/A300 XT OPERATING MANUAL REFERENCE CAUTION: When the procedure provided in this section is used to change the Battery, you must be sure that the case o-ring is not pinched and that the unit is water tight before conducting diving actvities. Pre dive pressure testing by an Authorized AERIS facility is highly recommended. © 2002 Design, 2012 44 Doc. No.
A300/A300 XT OPERATING MANUAL PC INTERFACE The A300 and A300 XT are configured with Data Ports (Fig. 121a, 122a) that enable their attachment to an Interface System capable of connection to a PC through a USB port. a A USB Driver, provided as part of the optional Interface System, must be installed on the PC. The unit will check for an external access request every second while in Surface Mode (NORM, TECH, GAUG, or FREE). Fig. 121 - DATA PORT (A300) Checks are not made if the activation contacts are wet.
A300/A300 XT OPERATING MANUAL CARE AND CLEANING Protect your unit from shock, excessive temperatures, exposure to chemicals, and tampering. Protect the lens against scratches with a Instrument Lens Protector. Small scratches will naturally disappear underwater. • Soak and rinse the unit in fresh water at the end of each day of diving, and check to ensure that the areas around the Low Pressure (Depth) Sensor (Fig. 124a, 125a), PC Interface Data Port (Fig.
A300/A300 XT OPERATING MANUAL 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 unit to an Authorized AERIS Dealer, and DO NOT attempt to use it until it has received factory prescribed service.
A300/A300 XT OPERATING MANUAL ALTITUDE SENSING AND ADJUSTMENT Prior to the first dive of a series of repetitive dives, Altitude (i.e., ambient pressure) is measured upon activation, then 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.
