RESPONSIBLE COMPUTER DIVING
• Always Plan Each Dive.
• Always Limit Your Dive to the Level of Your Training and Experience.
• Always Make Your Deepest Dive First.
• Always Make The Deepest Part of Every Dive First.
• Check Your Dive Computer Often During the Dive.
• Do a Safety Stop on Every Dive.
• Allow an Adequate Surface Interval Between Each Dive.
• Allow Adequate Surface Intervals Between Each Day of Diving (12 Hours or
Until Your Dive Computer Clears of residual nitrogen).
THE CODE OF THE RESPONSIBLE DIVER
• As a Responsible Diver, I understand and assume the risks I may encounter
while diving.
RESPONSIBLE DIVING BEGINS WITH
• Diving within the limits of my ability and training.
• Evaluating the conditions before every dive and making sure they t my
personal capabilities.
• Being familiar with and checking my equipment before and during every
dive.
• Knowing my buddy's ability level as well as my own.
• Accepting the responsibility for my own safety on every dive.

THIS MANUAL
The intent of this manual is to consolidate information that is common to the
various models of AERIS dive computers.
It is imperative that you read and understand this manual, as well as the
OPERATING MANUAL for your specic model dive computer prior to diving with it.
NOTE: In the event that information provided in the OPERATING MANUAL
varies from information provided in this Safety and Reference Manual, the
OPERATING MANUAL shall be the overriding document to refer to.

SYMBOLS
Symbols used in this manual and the dive computer operating manuals to bring your atten-
tion to information having various degrees of importance are -
NOTE: Represents important information.
CAUTION: Denotes instances that if not handled properly could result in
damage to the dive computer.
WARNING: Emphasizes conditions and procedures that could result in
serious injury or death if not corrected or followed properly.
__________________________________________________________________________
NOTE: Information in this manual relating to nitrox and oxygen features
only applies if you are using a dive computer specically set for dives using
nitrox as a breathing gas.
Throughout this manual and the operating manuals, reference is made to the term
'breathing gas'. The rational being that most AERIS dive computers can be used for 'air'
dives or 'nitrox' dives. For clarity these terms are defined as -
Breathing Gas - the gaseous mixture breathed during a dive.
Air - a breathing gas that contains approximately 21% oxygen and 79% nitrogen
(nature's common nitrogen-oxygen mixture).
Nitrox - a nitrogen-oxygen breathing gas that contains a higher fraction of oxygen than
Air (22 to 99% O2).

INTRODUCTION
Welcome to AERIS and thank you for choosing one of the finest dive computers available
Worldwide !
AERIS dive computers have a wide array of features and functions that are described in
detail in the Operating Manual for the specific model that you have.
It is extremely important that you read the Operating Manual and
understand it completely before attempting to use your new AERIS dive
computer.
Each numeric and graphic display represents a unique piece of information. It is
imperative that you understand the formats, ranges, and values of the information
represented to avoid any possible misunderstanding that could result in error.
While underwater with AERIS dive computers that have Bar Graphs, you can quickly verify
that you're not getting too close to the no decompression limit or the limit for exposure to
oxygen (accumulation), or ascending too fast.
Remember that technology is no substitute for common sense, and a dive computer only
provides the person using it with data, not the knowledge to use it. Remember also that
the dive computer does not actually measure and test the composition of your body tissue
and blood.

WARNINGS and SAFETY RECOMMENDATIONS Relating to INTENDED USE
• AERIS dive computers are intended for use by recreational divers who have
successfully completed a recognized course in SCUBA diving, and have
knowledge of the potential risks and hazards of SCUBA diving.
• Oxygen features are intended for use by divers who have successfully
completed a recognized course in diving with enriched nitrogen-oxygen
(Nitrox) mixtures, and have knowledge of the potential risks and hazards of
diving with Nitrox.
• AERIS dive computers are NOT for use by commercial divers.
• AERIS dive computers should NOT be utilized for any competitive, or
repetitive square wave dives as they are intended solely for recreational use
and multilevel diving.
• As with all underwater life support equipment, improper use or misuse of
AERIS dive computers can result in serious injury or death.
• If you do not fully understand how to use the dive computer, or if you have
any questions, you should seek instruction in its use from your Authorized
AERIS Dealer before diving with it.

DIVE COMPUTER PERFORMANCE
• Algorithm - Pelagic DSAT.
• No Deco Limits - closely follow PADI RDP.
• Altitude corrections and Oxygen limits - based on NOAA tables.
DSAT* has been the standard used by AERIS in all of its dive computers until this time. It
features NDLs that are based on exposures and test data which also formed validation for
the PADI RDP. Data consists primarily of No Deco, multi level, repetitive dives at sea level.
It imposes restrictions for repetitive Deco dives, considered more risky.
*DSAT - published and protected by Diving Science and Technology (subsidiary of PADI).
ALTITUDE DIVING
Atmospheric pressure decreases as Altitude increases above sea level. Weather systems
and ambient temperature also affect barometric pressures. Consequently, Depth reading
instruments that do not compensate for the decrease in ambient pressure indicate Depth
readings shallower than the Depth they are actually at.
AERIS dive computers automatically compensate for decreased ambient pressures for
Altitudes between 3,000 (915 meters) and 14,000 feet (4,270 meters). Their programs
compensate for high altitudes by reducing No Decompression and Oxygen Exposure Lim-
its (times), thus adding a larger zone of caution.

10
WARNINGS and SAFETY RECOMMENDATIONS relating to ALTITUDE
• Diving at high altitude requires special knowledge of the variations imposed
upon divers, their activities, and their equipment by the decrease in
atmospheric pressures. AERIS recommends completion of a specialized
Altitude training course by a recognized training agency prior to diving in
high altitude lakes or rivers.
• Altitude compensation provided takes place at 1000 foot (305 meter) intervals
beginning at 3001 feet (916 meters) elevation. Elevation is based upon
samples of Ambient Pressure taken every 30 minutes when the computer
is not activated and every 15 minutes when it is activated. Samples are not
taken and compensation is not provided at any time when the unit is wet.
• When returning to lower altitudes, diving should not be conducted until the
dive computer automatically clears of any residual nitrogen, and oxygen,
loading and resets to operate at the new altitude.
• Repetitive dives in a series should only be conducted at the same Altitude
as that of the rst dive of that series. Repetitive dives made at a different
Altitude will result in an error equal to the difference in barometric pressure,
and possibly a false dive mode with erroneous data.
• If an AERIS dive computer is activated at an elevation higher than 14,000 feet
(4,270 meters), it will immediately shutdown or revert to Watch Mode.
