RESPONSIBLE COMPUTER DIVING
Responsible
Since the advent of dive computers, it is a common mistake to assume that the old traditional rules of diving no longer apply,
but the truth is just the opposite. Before you dive using your ReACT Pro, keep these basic rules in mind:
Plan each dive, and dive your plan - Your ReACT Pro was not designed to make decisions for you, only to provide
you with the information you need to make responsible decisions for yourself. This begins with a dive plan that
will help you avoid a low air or decompression situation.
Do not plan any dive that exceeds your training or experience level.
Inspect your computer before every dive - If it shows any signs of damage or abnormal function, DO NOT dive with
it until it has received factory service.
Make your deepest dive first - When making repetitive dives, it is imperative to ensure that each consecutive dive
is shallower than the one before. This will allow your body's slower tissues to continue outgassing nitrogen.
Make the deepest part of your dive first, and gradually work your way to the surface using a staircase profile - The
ability to perform multilevel diving is one of the most important contributions of a dive computer, and you should
take advantage of it. It will increase your bottom time and at the same time decrease your risk of decompression
sickness.
Ascend slowly by following an ascent line whenever possible, or by ascending diagonally toward the surface - Watch
the Ascent Rate Indicator closely while you ascend, and keep it in the green zone as much as possible.
A Safety Stop of 3 minutes or more is recognized as a prudent action to reduce the probability of bubble forma-
tion in divers.

DECOMPRESSION MODEL
The programs within the ReACT Pro simulate the absorption of nitrogen 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 ReACT Pro dive computer model is based upon the latest research and experiments in decompression theory.
Still, using the ReACT Pro, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e.
the bends. Every divers physiology is different, and can even vary from day to day. No machine can predict how your body will react to a particular dive pro-
file.

INTRODUCTION
Congratulations on your recent purchase of the Genesis ReACT Pro !
Your ReACT Pro presents the information that you need before, during, and after your air (or nitrox) dives using an intuitive
combination of easy to read displays and unique identification icons.
Tissue loading of nitrogen and ascent rate are presented as segmented bar graphs alongside color coded reference indicators
that bring quick focus to these important status displays.
As you progress through this instructional guide, you will become familiar with all of the unique functions and features available and see examples of the displays that you could expect to see in the various operational modes. Although it will require
an initial investment of time to become acquainted with the various icons and symbols, youll soon agree that your ReACT
Pro is easy to understand and use.
Due to the importance that you understand the ReACT Pro thoroughly prior to using it, information will be expanded upon
and some refreshed as you proceed. Relax and read through the complete owner's manual.
It is extremely important that you:
Read this owner's manual in sequence and understand it completely before attempting to use the ReACT Pro.
Check the ReACT Pro frequently during your dive.
You must also be a trained diver, certified by a recognized training agency in SCUBA diving.
Prior to using the oxygen related features of the ReACT Pro, you must also be trained and certified for diving
with enriched nitrogen-oxygen (nitrox) breathing gas mixtures by a recognized training agency.
12
ReACT Pro
Remember that the rules you learned in your basic SCUBA certification course still apply to the diving you will do while using a dive computer - some will become even more important. 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.
WARNING: Inspect your ReACT Pro prior to every dive, checking for any signs of the entrance of
moisture, damage to the buttons, or damage to the LCD display. If these or other signs of damage
are found, return the unit to an Authorized Genesis Scuba Dealer. DO NOT attempt to use it until it
has received factory service.
CONTROL BUTTONS
The ReACT Pro is a unique dive computer with interactive controls that allow you to select various display options and access
specific information when you choose to see it. These are referred to as the LEFT (L) and RIGHT (R) buttons (Fig. 1).
The control buttons can be pressed repeatedly, or held in to scroll and continue as you set or access different display modes.
On the surface the control buttons are used to activate the ReACT Pro; activate the backlight; access the Date/Time, Fly, Plan, and Log modes; set variables such as FO2, Date/Time, etc.
The buttons can also be used to access an External Access mode to download (copy) dive data to
a unique PC log/profile program.
Underwater, the buttons are used to activate the backlight and view Alternate displays of information.

PO2
The ReACT Pro uses Genesis Scuba's unique Dive Profile Diagram (Fig. 2a) and easy to understand symbols, displaying information where you would expect it to be when looking at a log profile.
When you enter Special Situations, such as Decompression, High PO2, High O2, and Out of
Range modes, an UP Arrow symbol (Fig. 2b) will appear in the middle portion of the display as a
warning that a controlled ascent is required.
It is imperative that you understand the formats, ranges, and values of the information presented
by the ReACT Pro's numeric and graphic displays to avoid any possible misunderstanding that
could result in error.

NOTE: Throughout this owner's manual reference is made to the term
N
''breathing gas'. The rationale being that the ReACT Pro 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.
PO2
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 (22 to 50%) than air.
BAR GRAPHS
Two segmented bar graphs appear around the perimeter of the screen next to green, yellow, and
red color coded portions of the peripheral decal that denote normal, caution, and danger zones,
respectively.
When underwater, you can quickly focus on the bar graphs to make sure that they are in the
green and you are not getting too close to the no decompression limit or ascending too fast.
Ascent Rate Indicator (ARI)
The Ascent Rate Indicator located along the bottom of the LCD (Fig. 3a) is provided to help you
avoid excessive Ascent Rates by providing a visual representation of ascent speed, rather than
just showing that you are ascending too fast.
The LCD displays up to 5 segments that may be considered an Ascent Rate speedometer. Green
is a 'normal' rate, yellow a 'caution' rate, and red is 'Too Fast'. The segments of the Ascent Rate
Indicator represent 2 sets of speeds which change at a reference depth of 60 feet (18 meters).
Refer to the chart at the right for segment values.
When your ascent rate exceeds the maximum recommended rate of 60 feet (18 meters) per
minute when deeper than 60 feet (18 meters) or 30 feet (9 meters) per minute when shallower
than 60 feet (18 meters), the bar graph segments will enter the red 'Too Fast' zone at which time
the Audible Alarm will sound and all 5 segments will flash once per second until your ascent
speed is slowed.

Nitrogen Bar Graph (NiBG)
The Nitrogen Bar Graph located around most of the perimeter of the LCD (Fig. 4a) represents
tissue loading of nitrogen, showing your relative no decompression or decompression status. As
your depth and elapsed dive time (BT) increase, segments will add to the graph, and as you ascend to shallower depths, the bar graph will begin to recede, indicating that additional no decompression time is allowed for multilevel diving.
The Nitrogen Bar Graph also assists you with managing decompression by filling red 'ceiling
stop required' segments which are described in more detail in the Special Situations section of
this manual.
The Nitrogen Bar Graph monitors 12 different nitrogen compartments simultaneously and displays the one that is in control of your dive at that time. It is divided into a green No Decompression zone, a yellow Caution zone, and a red DECO (decompression) zone.

Time displays are shown in hour:minute format (i.e., 1:09 represents one hour and nine minutes,
not 109 minutes!). The colon that separates hours and minutes blinks once per second when the
display is indicating real time such as Surface Time, Bottom Time, and Time of Day. NDL,
OTL, TAT, Deco Stop Time, Time to Fly, and Time to Desaturate are calculated projections of
time and use a solid (non-blinking) colon to indicate that they are counting down.
TEMPERATURE DISPLAY
While in the Surface Mode, Ambient Temperature (Fig. 9a) will be displayed for 10 seconds in
place of Surface Time when the LEFT button is pressed. During a dive, Water Temperature is
displayed when the LEFT button is pressed 2 times to view the Second Alternate display.
If the Temperature exceeds a value of '99', two dashes ( - - ) will be displayed on the screen until
the unit's temperature decreases to '99'.
While Temperature is displayed, access can be gained to a Reset feature described later.
BACKLIGHT FEATURE
On the surface, while in Surface Mode or Fly Mode, the ReACT's Hydroglow Backlight will illuminate the display when the RIGHT button is pressed and released. If the button is kept depressed, the Backlight will not come on.
During a dive, the Backlight will illuminate the display when the RIGHT button is pressed. The
display will remain illuminated as long as the Button is pressed, plus 10 seconds after being released.
OPERATING TEMPERATURE
The ReACT Pro will operate in water temperatures from 28° to 95° F (-2 to 35 °C) and out of the
water from 20° to 140°F (-6 to 60 °C). At extremely low temperatures, the LCD may become
sluggish, but this will not affect it's accuracy. If stored or transported in extremely low temperature areas (below freezing), warm the module and battery with body heat before diving.

AUDIBLE ALARM
When Cautionary situations activate the Alarm, the ReACT Pro will emit a beeping sound as a warning. When the situation
corrected, the Alarm will cease. It will sound again if the same condition returns, or another Alarm condition occurs.
A single BEEP is emitted -
after the unit performs a Diagnostic check upon push button activation.
upon ascending to the No Deco Safety Stop depth of 20 feet (6 meters).
One BEEP per second is emitted for 10 seconds-
upon entry into Decompression Mode.
when PO2 reaches 1.40 ATA.
when PO2 reaches 1.60 ATA.
upon Ascending above a Required Decompression Stop Depth.
upon Descending deeper than 330 feet (99.5 meters).
when Ascent rate exceeds 60 feet (18 meters) per minute when depth is greater than 60 feet (18 meters), or 30 feet (9
meters) per minute at 30 feet (9 meters) or shallower. The Beeping will continue until the Ascent speed is reduced.
when O2 Accumulation becomes equal to or greater than allowable per dive limit, or limit for a 24 hour period.
when the Decompression obligation requires a Stop Depth greater than 60 feet (18 meters).
A single long BEEP is emitted for 3 seconds -
when above a required Decompression Stop Depth for more than 5 minutes.
when the Decompression obligation requires a Stop Depth greater than 70 feet (21 meters).
upon being on the surface for 5 minutes after a Delayed Violation (described in the Special Situations section).

E
to 0. The left digit of the Main Time display and the lower Time display do not contain seg-
C
O
ments in their top/left positions.
While conducting diagnostics, the display is illuminated by the backlight as it checks its display
functions to ensure that everything is working properly and that battery voltage is sufficient to
complete a full day of diving. If there is not enough battery voltage, the unit will either deactivate itself or would not have activated at all.
WARNING: If the Low Battery symbol (Fig. 10a) is still displayed following
E
diagnostics, Genesis Scuba strongly recommends that you DO NOT dive
until the battery is replaced.
When the button is held depressed as the Diagnostic countdown reaches 00, a Serial Number
screen appears displaying the units firmware code Revision Number and Serial Number for as
long as the button is held depressed (Fig. 11). Upon releasing the button, the unit shuts Off.
The unit will automatically turn OFF 2 hours after activation if no dive is made. If the water activation contacts are still bridged (the unit is wet), it automatically reactivates.
WATER CONTACT ACTIVATION (BACKUP METHOD)
NOTE: Water contact will only activate the unit if the Wet Activation
N
feature is Set ON (a user setting).
The ReACT Pro has 2 contacts that cause it to activate when the space between the contacts is
bridged by a conductive material (e.g., water contact) and enter Surface Mode.
If the Wet Activation feature is Set On and the water contacts are bridged when the unit shuts
Off, it will automatically reactivate.
WARNING: Never attempt to activate the ReACT Pro underwater. This
may result in inaccurate depth and no-decompression time displays. If the
unit is activated when deeper than 4 feet (1 meter) underwater, or at
elevations higher than 14,000 feet (4,267 meters), it will perform a
diagnostic check followed by immediate shutdown.
Upon activation and every 30 minutes while on the surface, the ReACT Pro will also check the
ambient barometric pressure, and calibrate its present depth as zero. At elevations of 2,000 feet
(610 m) or higher, it will recalibrate itself to provide adjusted No Decompression and O2 limits.
WARNING: If any display or function varies from the information
presented here, return the ReACT Pro to your Authorized Genesis Scuba
Dealer for inspection.
