DECOMPRESSION MODEL
The programs within the ProPlus 4.0 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 ProPlus 4.0 dive computer model is based upon the latest research and experi­ments in decompression theory. Still, using the ProPlus 4.0, just as using the U.S. Navy (or other) No Decompression Tables, is no guar-
antee of avoiding decompression sickness, 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 particular dive prole.

PROPLUS 4.0 OPERATING MANUAL
BASICS
The ProPlus 4.0 is an easy to use dive computer utilizing a two button interface. Divers may choose between either Dive or Gauge Mode. Though the ProPlus 4.0 is easy to use, you will get the most out of your new ProPlus 4.0 if you take some time to familiarize yourself with its displays and operation. Information has been organized into easy to follow sections to aid you in learning all you need to know. There is also a glossary at the end of this guide for any terms that may sound unfamiliar to you.
ACTIVATION
To activate the ProPlus 4.0, press and release either button. The ProPlus 4.0 will also turn on if its metal contacts become wet and you descend greater than 1.5 m (5 ft) for 5 seconds. The H2O ACT (water activation) feature may be disabled if that is your preference. Disabling the H2O ACT feature is described in the Dive Surface Mode chapter, p. 26.
• Upon activation the unit will enter a Diagnostic Mode. The ProPlus 4.0 checks the display and voltage at this time to ensure that everything is
within tolerance.
• It will also check ambient barometric pressure, and calibrate present depth as 0 ft (m). When at 3001 ft (916 m), or higher, it will adjust depth for
the higher altitude.
• After the Diagnostic check, the ProPlus 4.0 will display the surface screen in Dive Mode.
NOTE: The ProPlus 4.0 has no off button or command. If no buttons are pressed or dives made within 10 minutes the computer
will enter Sleep Mode. The screen and Bluetooth (if set ON) shut down, to save battery life, while in Sleep Mode. To wake the computer press any button. Additionally, the unit will completely shut itself off after 2 hours of inoperation. However, the ProPlus
4.0 will stay on, in Sleep Mode, for a 24 hour period after the dive, counting down FLY (time to fly) and SAT (desaturation time) if a dive has been made.

PROPLUS 4.0 OPERATING MANUAL
DTR (DIVE TIME REMAINING)
The ProPlus 4.0 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 identied by the NO DECO (no decompression) min or O2
(Oxygen Time Remaining) min icons.
NO DECOMPRESSION
No Decompression is the maximum amount of time that you can stay at your present depth before entering decompression. It is calculated based on the amount of nitrogen absorbed by hypothetical tissue compartments. The rates each of these compartments absorb and release nitrogen is math­ematically modeled and compared against a maximum allowable nitrogen level.
Whichever compartment is closest to this maximum level is the controlling compartment for that depth. Its resulting value NO DECO (no decompres­sion) will be displayed. It will also be displayed graphically as the Tissue Loading Bar Graph, see Bar Graphs later in this section.
As you ascend, the Tissue Loading Bar Graph will recede as control shifts to slower compartments. This is a feature of the decompression model that is the basis for multilevel diving, one of the most important advantages that Oceanic dive computers offer.
DTR is No Decompression
O2 MIN (OXYGEN TIME REMAINING)
When set for nitrox operation, O2 SAT (Oxygen Saturation) during a dive is displayed on an ALT screen as a percentage of allowed saturation
identied by the O2 SAT icon. The limit for O2 SAT (100%) is set at 300 OTU (Oxygen Tolerance Units) per dive or 24 hour period. See the chart at the back of this manual for specic times and allowances. O2 SAT and O2 MIN values are inversely related; as the O2 SAT value increases the O2
MIN value decreases.
When the O2 MIN value becomes less than the No Decompression calculations for the dive, DTR (Dive Time Remaining) will be controlled by O2
SAT and the O2 MIN value will be displayed as the DTR on the Dive Main screen, identied by the O2 MIN icon.

BAR GRAPHS
The ProPlus 4.0 features two specic bar graphs.
1. The one on the left represents nitrogen loading. It is referred to as TLBG (Tissue Loading Bar Graph).
2. The one on the right represents ascent rate. It is referred to as the VARI (Variable Ascent Rate Indicator) Bar Graph.

VARIABLE ASCENT RATE INDICATOR
The VARI (Variable Ascent Rate Indicator) Bar Graph provides a visual representation of ascent speed (i.e., an ascent speedometer). When the
ascent is faster than the recommended 30 fpm (9 mpm), the bar graph will ash red until the ascent is slowed.

TISSUE LOADING BAR GRAPH
The Tissue Loading Bar Graph represents your relative No Decompression or Decompression status. The rst four segments represent No Decompres­sion status and the fth indicates a Decompression condition. As your Depth and Elapsed Dive Time increase segments are added. As you ascend
segments recede, indicating that additional No Deco (decompression) time is available. The ProPlus 4.0 monitors twelve different nitrogen compart­ments simultaneously and the N2 Bar Graph displays the one that is in control of your dive at any given time.
DUAL ALGORITHM®
The ProPlus 4.0 is congured with 2 algorithms which allows you to choose which set of NDLs (No Decompression Limits) will be used for nitrogen/
oxygen calculations and displays relating to Plan Mode and DTR (Dive Time Remaining) for NORM dives.
You can select DSAT or Z+ prior to new dives. Also, the selection can be changed after dives once Desaturation Time decreases to 0:00, otherwise the selection will lock in for 24 hours after the last dive.
DSAT was the original standard used by Oceanic in all of its dive computers until the dual function was implemented several years ago. It features NDLs that are based on exposures and test data which also formed validation for the PADI RDP. It imposes restrictions for repetitive Decompression dives which are considered more risky than general No Deco dives.
Z+ (the Pelagic Z+ algorithm) performance is based on Buhlmann ZHL-16c. It features NDLs that are considerably more conservative than the DSAT version especially at shallower depths.
To create even greater margins of safety with respect to decompression, a Conservative Factor as well as Deep and Safety Stops are available and can be activated for NORM No Decompression dives.
CONSERVATIVE FACTOR
When the CF (Conservative Factor) is set On, the dive time remaining, No Decompression/Oxygen Time Remaining, which are based on the algo­rithm and used for N2/O2 calculations and displays relating to Plan Mode, will be reduced to the values available at the altitude level that is 3,000 ft (915 m) higher than the actual altitude at activation. Refer to the charts in the back of this manual for dive times.
DEEP STOP
When the DS (Deep Stop) selection is set ON, it will trigger after descending deeper than 80 ft (24 m). The ProPlus 4.0 then calculates (continually updating) a Stop Depth equal to ½ the Max Depth.
NOTE: The Deep Stop feature only works in Norm mode while within No Decompression times.
• While 10 ft (3 m) deeper than the calculated Deep Stop, you will be able to access a Deep Stop Preview screen that will display the current calcu-
lated Deep Stop Depth/Time.
• Upon initial ascent to within 10 ft (3 m) below the calculated Stop Depth, a Deep Stop screen displaying a Stop Depth at ½ the Max Depth will appear with a countdown timer beginning at 2:00 (min:sec) and counting down to 0:00. If you descend 10 ft (3 m) below, or ascend 10 ft (3 m) above, the calculated Stop Depth for 10 seconds during the countdown, the No Decompression Main will replace the Deep Stop Main display and the Deep Stop feature will be disabled for the remainder of that dive. There is no penalty if the Deep Stop is ignored.
• In the event that you enter Decompression, exceed 190 ft (57 m), or a High O2 SAT (Oxygen Saturation) condition, ≥ 80%, occurs, the Deep
Stop will be disabled for the remainder of that dive.
• The Deep Stop is disabled during a High PO2 Alarm condition, ≥ set point.

SAFETY STOP
Upon ascent to within 5 ft (1.5 m) deeper than the SS (Safety Stop) depth set for 1 second, on a No Decompression dive in which depth exceeded 30 ft (9 m) for 1 second, a beep will sound and a Safety Stop at the depth set will appear on the Dive Main display with a countdown beginning at the Safety Stop time set and counting down to 0:00.
• If the Safety Stop was set for OFF, the display will not appear.
• In the event that you descend 10 ft (3 m) deeper than the Stop Depth for 10 seconds during the countdown, or the countdown reaches 0:00, the No Decompression Main screen will replace the Safety Stop Main screen which will reappear upon ascent to within 5 ft (1.5 m) deeper than the Safety Stop depth set for 1 second.
• In the event that you enter Decompression during the dive, complete the Decompression obligation, then descend below 30 ft (9 m); the Safety
Stop Main will appear again upon ascent to within 5 ft (1.5 m) deeper than the Safety Stop depth set for 1 second.
• If you ascend to 3 ft (0.9 m) of the surface for 1 second, the Safety Stop will be canceled for the remainder of that dive.
• There is no penalty if you surface prior to completing the Safety Stop or choose to ignore it.
LOW BATTERY
WARNING: DO NOT dive with a low battery. Charge the battery before diving if your ProPlus 4.0 indicates the Battery Low
Warning or Alarm.
