The program within the i330R simulates the absorption of inert gases into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The i330R dive computer model is based upon the latest research and experiments in decompression theory.
This is an important reason for not pushing the tables, oxygen exposure limits, or entering decompression without proper training. If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your i330R, a backup instrument system is highly recommended.
• If you exceed certain limits, the i330R will not be able to help you get safely back to the surface. These situations exceed tested limits and can result in loss of some functions for 24 hours after the dive in which a violation occurred.
Dive, Gauge, and Free Mode. Though the i330R is easy to use, you will get the most out of your new i330R if you take some time to familiarize yourself with its displays and operation.
GETTING STARTED ACTIVATION To activate the i330R, press and release any button. The i330R will also turn on if you descend below 1.5 m (5 ft) for 5 seconds. • Upon activation, the unit will display the Activation screen and perform a diagnostic check. The i330R checks the display and voltage at this time to ensure that everything is within tolerance.
They are also used to enter settings and acknowledge the audible alarm. Pressing different combinations of these buttons will navigate through different menus and options of the i330R. The symbols in the table below will illustrate how to proceed through the menus.
DIVE FEATURES DTR (DIVE TIME REMAINING) The i330R constantly monitors No Decompression status and O2 Accumulation, and will display whichever time is the least amount available as DTR on the No Decompression Dive Main screen. The Time being displayed will be identified by the NO DECO (no decompression time) or O2 TIME icons.
DEEP STOP When the Deep Stop selection is set ON, it will trigger after descending deeper than 24 m (80 ft). The i330R then calculates (continually updating) a Stop Depth equal to ½ the Max Depth.
10 seconds while the audible alarm sounds. Then the icon shall be solid and the message removed. All functions shall continue to be available. WARNING: Recharge the battery before diving if your i330R indicates the Battery Low Warning or Alarm.
The battery icon shall continue flashing and the LOW BATTERY message will be removed. WARNING: The i330R will shut down when the battery is completely exhausted. Recharge the battery before making additional dives. End your dive as soon as is safe if your i330R indicates the Battery Low Alarm during a dive.
AIR with no PO alarm value for Gas 1, and OFF for Gas 2 and 3. If you save a nitrox mix value for any gas, the i330R will highlight the PO alarm value allowing it to be set. Additionally, the i330R allows for each gas (1 - 3) to have individual PO alarm settings.
2. Auto Dim While underwater the i330R screen dims after a set time interval from the last button press. This is done to reduce distractions during the dive and to conserve power. The i330R allows you to cus- tomize the time interval and degree of dimming.
Sleep Mode (screen is turned off) or a dive is started. The i330R reactivates "sniffing" mode when the i330R returns to Surface Mode after a dive or a button is pushed to wake the computer from Sleep Mode on the surface.
DIVE SURFACE MODE 6. SAMPLING RATE The Sample Rate controls how frequently the i330R stores a data snapshot for Diverlog + Down- load during a dive. Setting options are 2, 15, 30, or 60 second intervals. Shorter intervals will provide a more precise record of your dives.
Set Mode allows you to choose between Dive (standard recreational dive), Gauge, and Free (free diving) modes of operation. NOTE: Once a dive is conducted in Gauge mode, the i330R shall operate with limited functions without any decompression or oxygen monitoring functions. A 24 hour surface interval shall be required for the unit to operate as a full function dive computer in Dive or Free mode.

Upon ascending to 0.9 m (3 ft) the i330R transitions to Dive Surface mode. NOTE: The i330R requires a 10 minute surface interval to record a subsequent dive as a separate dive in the Log. Otherwise, the dives will be combined and recorded as a single dive in the i330R memory. elapsed dive...
DIVE OPERATION COMPLICATIONS The preceding information has described standard dive operations. Your new i330R is also designed to help you to the surface in less than ideal situations. The following is a description of these situations. Take some time to familiarize yourself with these operations before diving your i330R.
Stop Main Screen will be displayed. • If the DV1 status is ignored, the i330R will enter DV1 Surface mode for 5 minutes upon surfacing from the dive. The down arrows and Decompression Stop depth/time will be displayed. After 5 minutes on the surface in DV1 mode, the unit will enter VGM (Violation Gauge Mode).
DEEP, and the up arrows will flash. Additionally, Current Depth will only indicate dashes signifying that you are too deep. * The maximum functional depth (330 ft / 100 m) is the depth at which the i330R can properly perform calculations or provide accurate display information.
INITIATING A DIVE With the i330R in Gauge Mode, a dive will commence upon descending to 1.5 m (5 ft) for longer than 5 seconds. Below is a diagram to help you navigate Gauge Dive Mode functions. The dive will end and revert to Surface Mode upon ascent to 0.9 m (3 ft) of depth for at least 1 second.
DEEP will flash. At the same time, the up arrows will flash and depth will only indicate dashes signifying that you are too deep. The max depth will also be represented by dashes. * The maximum functional depth (100 m / 330 ft) is the depth at which the i330R can properly perform calculations or provide accurate display information.
• The mathematical models currently used in the i330R are based on no decompression/decompression multilevel repetitive dive schedules. • These algorithms do not take into account the physiological changes associated with the high pressures that competitive type free diving can expose a diver to.
COUNTDOWN TIMER (CDT) The i330R allows you to set a CDT time from 0:01 - 59:59 (min:sec). On the surface the CDT must be started and stopped in the CDT Status screen by selecting ON or OFF. The CDT will run in the background, while on the surface and during dives, until it counts down to 0:00, or it is turned OFF.
INITIATING A DIVE With the i330R in Free Mode, a dive will commence upon descending to 1.5 m (5 ft) for longer than 5 seconds. Below is a diagram to help you navigate Free Dive Mode functions. The dive will end and revert to Surface Mode upon ascent to 0.9 (3 ft) of depth for at least 1 second.
• Soak and rinse the i330R in fresh water at the end of each day of diving, and check to ensure that the areas around the Low Pressure (Depth) Sensor, electrical contacts, and buttons are free of debris or obstructions.
• No adjustments are made during any time that the wet contacts are bridged. When diving in high altitude waters from 916 to 4,270 m (3,001 to 14,000 ft), the i330R automatically adjusts to these conditions providing corrected depth, and reduced No Deco and O2 Times at intervals of 305 m (1,000 ft).
