ReACT Pro
The following icons are used throughout this manual to bring your attention to situations that require special consideration.
WARNING - used if serious injury or death could result if the procedure is not followed carefully.
CAUTION - used if a maintenance technique could result in damage to parts if that technique is not followed carefully.
NOTE - used to emphasize important information or maintenance technique.
N
RESPONSIBLE COMPUTER DIVING
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 formation in divers.

WARNINGS:
• The ReACT Pro is intended for use by recreational divers who have successfully completed a nationally
recognized course in scuba diving, and diving with enriched nitrogen-oxygen (nitrox) breathing gas
mixtures.
• It is intended only for no decompression diving, NOT intentional decompression diving.
• It must not be used by untrained persons who may not have knowledge of the potential risks and haz-
ards of scuba diving, and diving with enriched nitrogen-oxygen (nitrox) mixtures.
• You must obtain scuba certification, and certification in diving with enriched nitrogen-oxygen mixtures
(nitrox) before using the ReACT Pro if you have not already done so.
• It is NOT for use by military and commercial divers.
• It should NOT be utilized for any competitive, or repetitive square wave or decompression diving, as it
is intended solely for recreational use and no decompression multilevel diving.
• As with all underwater life support equipment, improper use or misuse of this product can cause seri-
ous injury or death.
• Never participate in sharing or swapping of a dive computer.
• Conduct your dives in such a manner so as to insure that you continuously check the computer's
proper function.
• Read and understand this owner’s manual completely before diving with the ReACT Pro.
• If you do not fully understand how to use this dive computer, or if you have any questions, you should
seek instruction in its use from your authorized Genesis dealer before you utilize this product.
• Never participate in sharing or swapping of a dive computer. Doing so may result in injury or death.
The ReACT Pro provides information based upon a diver’s personal dive profile, and therefore must
not be “shared” between divers. You should never, under any circumstances, swap your computer
with another unit between dives, or share your computer with another diver underwater.

PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:

no. 5,156,055).
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 sick-
ness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body will react to a par-
ticular dive profile.

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 avail-
able 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 icons, you’ll 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.

ReACT Pro
AS
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. Tech-
nology 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 vari-
ous display options and access specific information when you choose to see it. These are referred
to as the A (Advance) and S (Select) buttons (Fig. 1).
The buttons can be pressed repeatedly, or held in to scroll and continue as you set or access differ-
ent display modes.
On the surface the 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.
During dives, the buttons are used to activate the backlight and view Alternate displays of infor-
mation. Fig. 1 - Control Buttons

INTUITIVE DISPLAYS
The ReACT Pro uses Genesis Scuba's unique Dive Profile icon (Fig. 2a) and easy to understand
icons, 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 icon (Fig. 2b) will be displayed 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 manual reference is made to the term ''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.
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, re-
spectively.
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 FT (18 M). Refer to
the chart at the right for segment values.
When your ascent rate exceeds the maximum recommended rate of 60 FPM (18 MPM) when
deeper than 60 FT (18 M) or 30 FPM (9 MPM) when shallower than 60 FT (18 M), 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 tis-
sue loading of nitrogen, showing your relative no decompression or decompression status. As
your depth and bottom 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 NiBG also assists you with managing decompression by filling red 'ceiling stop required' seg-
ments which are described in more detail in the Special Situations section of this manual.
The NiBG 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.
The yellow Caution zone gives a visual representation of just how close you are to the no decom-
pression limit which allows you to make a decision regarding safety stop duration or necessity.
The red DECO zone alerts you to focus your attention on the current required DECO stop 'ceiling'
depth indicated by the bar graph segment. When stop depths of 50 FT (15 M) and 60 FT (18 M)
are required, all red segments are displayed and the required stop depth (50 or 60, or 15 or 18) is
displayed numerically.

DEPTH DISPLAYS
The Depth display indicates Depths from 0 to 399 FT (120 M) in 1 FT (.5 M) increments.
During a dive, Current Depth is displayed continuously on the Main display with the icon FT (or
M) below it (Fig. 5a).
When the LEFT button is pressed 1 time to view the first Alternate display, Maximum Depth and
the icons MAX and FT (or M) are displayed in place of Current Depth.
In the event that you descend deeper than 330 FT (99.5 M), 399 FT (120 M) when set for Gauge
Mode, the Depth display will show three dashes (- - -) to indicate that you have gone 'out of
range'. This is described in more detail in the Special Situations section of this manual.
During a Decompression Dive, required Ceiling Stop Depths of 50 FT (15 M) and 60 FT (18 M)
are displayed in the lower/right portion of the LCD. This is described in more detail in the Special
Situations section of this manual.
DATE DISPLAY
The Date (Month_Day) is displayed when the ReACT Pro is in Surface Mode (Fig. 6a/b). It is
not displayed in any other modes on the surface or during dives.

TIME DISPLAYS
The ReACT Pro has three time displays.
The largest display is the Main Time display (Fig. 8 - top row of digits). Indicated are theoreti-
cal No Decompression Limit (NDL), Oxygen Tolerance Limit (OTL), Elapsed Dive Time (BT),
Total Ascent Time (TAT), or Surface Time (indicated by the Wave icon below it), depending on
the operating mode that the ReACT Pro is in.
A second time display (Fig. 8 - middle row of digits) indicates Decompression Stop Time required
at the stop depth indicated, or Time to Desaturate after a dive, depending on the operating mode
that the unit is in.
The third time display (Fig. 8 - bottom row of digits) indicates Time of Day, or Time to Fly after a
dive, depending on the operating mode that the unit is in.
Each display is described in more detail in subsequent sections of this manual.
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_a) and Altitude level (Fig. 9A_b) will
be displayed when an Alternate display is accessed. During a dive, Water Temperature (Fig.
9B_a) is displayed when an Alternate display is accessed.
If the Temperature exceeds a value of '99', two dashes ( - - ) will be displayed on the screen until
the unit's temperature decreases to '99'.
BACKLIGHT FEATURE
On the surface, while in Surface Mode or Fly Mode, the ReACT's Hydroglow™ Backlight will il-
luminate the display when the S button is pressed and released. If the button is kept depressed,
the Backlight will not come on.
During dives, the Backlight will illuminate the display when the S 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 tempera-
ture 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 FT (6 M).
One BEEP per second is emitted for 10 seconds-
• upon entry into Decompression Mode.
• when Elapsed Dive Time, Depth, and/or Dive Time Remaining reach their Alarm Set Points.
• when PO2 reaches .20 (ATA) < Alarm Set Point value and at the Set Point.
• upon Ascending above a Required Decompression Stop Depth.
• upon Descending deeper than 330 FT (99.9 M), or 399 FT (120 M) when set for Gauge Mode.
• when Ascent rate exceeds 60 FPM (18 MPM) when depth is greater than 60 FT (18 M), or 30 FPM (9 MPM) at 30 FT (9
M) 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 FT (18 M).
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 FT (21 M).
• upon being on the surface for 5 minutes after a Delayed Violation (described in the Special Situations section).
