CompuMask Operating Manual, Doc. No.
WARNING: If your CompuMask stops working for any reason, it is important that you have anticipated this possibility and are prepared for it. This is an important reason for not pushing the no decompression and oxygen exposure limits, and a critical reason to avoid entering decompression. If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your CompuMask, a backup instrument system is highly recommended.
WARNING: Prior to diving with the CompuMask, you must also read and understand the AERIS Dive Computer Safety and Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
INTRODUCTION Welcome to AERIS and thank you for choosing the CompuMask ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the CompuMask as a dive computer. It is equally important that you read the AERIS Dive Computer Safety and Reference Manual (Doc. No. 12-7203) provided with your CompuMask. It contains information that you must become familiar with prior to diving with your CompuMask.
A diver who can read his or her instruments with uncorrected vision will be able to read the Mask display in all the environmental conditions described. CompuMask System components can be located and operated by a diver wearing a 7 mm thick three finger (lobster claw) wet suit glove. The equipment will not be impaired/ degraded when the diver is wearing a 7 millimeter wet suit or dry suit hood.
Ambient Light Levels The Mask's display is readable on the surface and while underwater in Ambient Light Levels ranging from no light to bright light (direct sun). Shading may be required on the surface in direct sunlight. Visibility The Mask's display is readable in external Visibility Conditions ranging from zero to infinite. It is readable as long as water does not cover the Display Optics. The Mask lens and Digital Optic System are capable of being prevented from fogging.
OPERATING MODE STRUCTURE The A (Top) button is used to access 3 Operating Modes (Fig. 1) that include NOR (Normal Air/Nitrox Dive Computer), GAU (Digital Gauge Mode), and FRE (Free Dive Mode). The screens of the Main Modes and Sub Modes will remain on display until a button is pressed to access another screen or Mode, activate a sequence, or for 2 minutes if no button is NORMAL (AIR/NITROX) pressed.
GAUGE Surface Mode allows access to ALT (Alternate) Displays, Set, Fly, Log, and History Modes. It also displays Tank Pressure. FRE Mode allows access to sub modes by first accessing NOR Surface Mode. It does not display Tank Pressure. Once a dive is made in GAUGE Mode, the CompuMask is locked into that Mode for 24 hours after the dive.
Situations that will activate the NOR/GAU 10 second Alarm include Air Time Remaining (ATR) at 5 minutes, then again at 0 minutes. ATR becomes less than No Deco and O2 Time Remaining for 1 minute. Turn Pressure at the Set Point selected. End Pressure at the Set Point selected. Descent deeper than the Max Depth Set Point selected. Dive Time Remaining at the Set Point selected. Elapsed Dive Time at the Set Point selected. PO2 increases to the Set Point selected.
3 short beeps (which cannot be disabled) are emitted for the following FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set ON). FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times. FREE Dive TLBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times. Entry into Deco during a FREE Dive (Permanent Violation) - 3 beeps 3 times. FREE Dive Mode Countdown Timer reaches 0:00 - 3 beeps 3 times.
POWER SUPPLY The CompuMask utilizes (1) 3 volt, type CR2 Lithium Battery that should provide 160 hours of operation over the temperature ranges specified with the Backlight ON continuously while set for maximum brightness (Level). The CompuMask checks its battery voltage every 2 minutes during surface operation. If the Mask's voltage decreases to the Warning level (2.75 volts), the Battery icon (shell with lid) will appear on Surface displays (Fig.
Transmitter Low Battery Warning/Alarm conditions are only displayed as a Transmitter Low Battery Status screen (Fig. 3) that comes On and alternates with the SURF MAIN screens when voltage decreases to the Warning level (2.75 volts). Each screen will be On for 3 seconds. Fig. 3 - TRANSMITTER LOW BATTERY Displayed on the Transmitter Status screen will be the graphics trtr (meaning Transmitter), Lo (meaning Low Voltage), and bAt (meaning Battery).
a As your Depth and Elapsed Dive Time increase, segments will add to the TLBG (Fig. 5A), and as you ascend to shallower depths, the segments of the TLBG will begin to recede, indicating that additional no decompression time is allowed. The TLBG monitors 12 different nitrogen compartments simulta- Fig. 5 - NOR DIVE MAIN neously and displays the one that is in control of your dive. It has 5 segments, the lower 4 represent No Decompression status and the one at the top indicates a Decompression condition.
Regardless of which parameter the Bar Graph is representing at the time, nitrogen calculations (if in NOR Nitrox or FRE Mode) and oxygen calculations (if in NOR Nitrox Mode) will continue to be performed in the background. While in NOR Mode, displays associated with oxygen and the O2 Bar Graph will be displayed if FO2 has been set at a value other than AIR (e.g., a numerical value) and the ALT 2 screen that displays oxygen related data is accessed.
PC INTERFACE Interface with a PC is accomplished by connecting the CompuMask to a PC USB Port using the ACI (AERIS Computer Interface) USB Interface Cable. The same Cable is used for Upload and Download. The software program is on the ACI CD, together with a USB Driver. The program's Help section serves as the User Manual and can be printed for personal use. The Settings Upload portion of the program is used to check the CompuMask's existing Settings and for entering settings into the CompuMask.
a b ALPHA / NUMERIC DISPLAYS Tank Pressure Display (NOR/GAU only) When the CompuMask's Receiver is active and properly Linked with a Transmitter, Tank Pressure from the Transmitter will be displayed on the NOR or GAU MAIN screens (Fig. 8a). Fig. 8 - NOR DIVE MAIN a Values of Pressure are displayed numerically from 000 PSI (00 BAR) up to 5000 PSI (345 BAR) in increments of 5 PSI (1 BAR). Depth Displays (all Modes) During dives, the Current Depth display (Fig.
Air Time Remaining (ATR) Display If the CompuMask's Receiver and a Transmitter are active and properly linked, ATR is displayed on the NOR or GAU Main Dive display as 1 - - with the ATR icon if > 60 minutes, then in decrements of 1 minute when it is <= 60 minutes (Fig. 11a). Time, Date, Temperature Displays a Time of Day and NOR/GAU Mode Time displays are shown in Fig. 11 - NOR DIVE MAIN hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes).
There is an ALT (Alternate) screen that displays Time of Day and Temperature. This common display (Fig. 12) can be accessed while operating in NOR, GAU, or FRE Modes while on the Surface and during Dives. Date is displayed only to identify dives when they are accessed Fig. 12 - DIVE ALT (Time/Temp) in the LOG Mode. When set for Imperial Units, Month is to the left of Day (Fig. 13a) separated by a decimal point (month.day). When set for Metric, Month is to the right of Day (day.month).
WARNING: Prior to diving with the CompuMask, you must also read and understand the AERIS Dive Computer Safety and Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
OPERATING MODES The CompuMask features 3 Operating Modes >> NOR - for Normal Air or Nitrox dives GAU - for dives with no Nitrogen/Oxygen calculations FRE - for dives with no SCUBA Fig. 14A - NOR SURF MAIN REMINDER: Once a dive is made in GAU Mode, the CompuMask is locked into that Operating Mode for 24 hours after the dive.
The CompuMask will enter Post Dive Surface Mode following a dive upon Ascent to 4 FT (1.2 M) for 1 second. The Surface Interval Time colon will flash during the first 10 minutes after a NOR/GAU dive, or first 1 minute after a FRE dive, indicating a Descent will be a continuation of that dive. During the first 2 hours after a dive, the SURF MAIN screen for the Operating Mode selected prior to the dive (NOR, GAU, or FRE) remains on display as the Default SURF MAIN screen. Fig.

WARNING: If your CompuMask stops working for any reason while operating as a Dive Computer, it is important that you have anticipated this possibility and are prepared for it. This is an important reason for not pushing the no decompression and oxygen exposure limits, and a critical reason to avoid entering decompression. If you dive in situations where your trip would be ruined or your safety would be jeopardized by losing the use of your CompuMask, a backup instrument system is highly recommended.
WARNING: Prior to diving with the CompuMask, you must also read and understand the AERIS Dive Computer Safety and Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
POSITIONING A TRANSMITTER AND MASK When installing a Transmitter on a Regulator First Stage (Fig. 55), it is important that it be properly positioned for actual use with the Mask. The Transmitter is a Battery powered electronic device that contains a Pressure Transducer designed to measure Pressure of a Tank that it is fitted to. It also contains a microcomputer that converts data from the Pressure Sensor and emits Radio Frequency data signals capable of being received by the electronics of the Mask.
An interruption lasting greater than 15 seconds will cause the Tank Pressure value and the Link (Signal) icon to flash on the Mask's display (Fig. 56). An interruption of the Link may also occur while operating within 3 feet (1 meter) of a running Dive Propulsion Vehicle. when using a Strobe (a temporary interruption may occur shortly after the Strobe flashes). within 6 feet (2 meters) of a PC CRT monitor, in which case Fig.
ATR will be displayed on the Main display (lower/left) when it is 60 minutes or less in decrements of 1 minute). In the event that ATR becomes less than 5 minutes during No Deco conditions, the Audible Alarm will sound, and the ATR value will flash (Fig. 58) until it is > 5 minutes. Fig. 58 - ATR ALARM (during No Deco) During other conditions, the Audible Alarm will sound, and the graphic ATR will flash in place of Dive Time Remaining (Fig. 59).
a As you ascend from Depth following a dive that has approached the No Decompression Limit, the TLBG segments will recede (Fig. 60a) 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 AERIS dive computers offer. The CompuMask's algorithm is based upon Haldanes theory Fig. 60 - TLBG using maximum allowable nitrogen levels developed by Merrill Spencer.
Oxygen Time Remaining (OTR) will then appear as the Dive Time Remaining (DTR) display (Fig. 62a) as signified by the OTR icon replacing the NDC icon. As Oxygen Accumulation continues to increase, segments will add to the O2BG. Fig. 62 - OTR is DTR a Air Time Remaining (ATR) The CompuMask calculates Air Time Remaining (ATR) using a patented Algorithm that is based on a diver's individual Air Consumption Rate and Current Depth.
ATR, identified by the ATR icon, is displayed digitally at the lower/left of the MAIN Dive screen (Fig. 63a). In the event that ATR becomes less than NDC and O2 Time, it will be displayed on the Main Display as Dive Time Remaining (DTR) until it becomes greater than one or the other. a Air Time Remaining (ATR) Alarm When ATR decreases to 5 minutes (0:05), the Audible Alarm will Fig. 63 - MAIN DIVE DISPLAY sound and the ATR value (lower/left) will flash.
ASCENT RATE ALARM Alarms associated with Ascent Rate are based upon 2 sets of speeds which change at a reference depth of 60 FT (18 M). The Audible will sound and the graphic SLO will flash in place of DTR (Fig. 65). The Audible will stop when acknowledged by Fig. 65 - ASCENT RATE ALARM pressing and releasing the A (Top) button, or after 10 seconds, or when the Ascent is slowed. The graphic will continue to flash until Ascent is slowed, then DTR (hr:min) will reappear.

Press/release the A (Top) button (< 2 sec) to revert to the MAIN display. NOTE: The Alternate Displays cannot be accessed during the time (10 seconds) when an Alarm is sounding.
a CONDITIONAL VIOLATION If you ascend shallower (Fig. 81a) than a Required Decompression Ceiling Stop Depth (Fig. 81b), the Audible Alarm will sound and the Full TLBG will flash. The Down Arrow will flash until you descend below the Required Stop Depth. If you descend to within < 9 FT (3 M) below the required Decompression Stop Depth before 5 minutes have elapsed, the CompuMask will continue to function in Decompression Dive b Fig. 81 - CONDITIONAL VIOLATION MAIN Mode.
DELAYED VIOLATION # 1 (Fig. 82) If you remain above the Required Deco Stop Depth for more than 5 minutes, the full TLBG and DOWN Arrow will flash until you descend below the Required Stop Depth. After the Audible stops (10 seconds), the TLBG will stop flashing. Fig. 82 - DELAYED VIOLATION # 1 The Down Arrow will continue to flash until you descend below the required Decompression Stop Depth. > Delayed Violation #1 is a continuation of a Conditional Violation. DELAYED VIOLATION # 2 (Fig.
After the Audible stops (10 seconds), the TLBG will stop flashing. The UP Arrow will continue to flash until you ascend to within 10 FT (3 M) below the 60 FT (18 M) Deco Stop Depth. When Delayed Violation #2 occurs, you must make a controlled Ascent to just deeper than and stay as close as possible to 60 FT (18 M) without causing the UP Arrow to flash. When the Required Stop Depth indicates 50 FT (15 M), etc., you can ascend to those Stop Depths and continue decompressing.
IMMEDIATE VIOLATION AND VIOLA GAUGE MODE If a Decompression Ceiling Stop Depth much greater than 60 FT (18 M) is required, an Immediate Violation Mode will be entered. This situation would be preceded by entering Delayed Violation #2. Fig. 85 - VIOLATION GAUGE MODE MAIN The CompuMask would then operate in Violation Gauge Mode during the remainder of that dive and for 24 hours after surfacing. Violation Gauge Mode turns the CompuMask into a digital instrument without any Deco or O2 monitoring functions.
The CompuMask will also enter a Violation Gauge Mode 5 minutes after surfacing from a dive in which a Delayed Violation occurred. Violation Gauge Mode on the Surface does not allow access to the SET F, PLAN, FLY, and SAT features/screens. The countdown timer that appears when you try to access the FLY screen does not represent Time to Fly. It is only provided to inform you of the time remaining before normal operation can resume with full CompuMask features and functions.
If PO2 continues to increase, the value displayed on the ALT 2 screen will increase in increments of 0.01 (ATA) to a maximum value of 5.00 (ATA).

WARNING: Prior to diving with the CompuMask, you must also read and understand the AERIS Dive Computer Safety and Reference Manual, Doc. No. 12-7203, which provides Important Warnings and Safety Recommendations as well as general product information.
a UPLOADING SETTINGS AND DOWNLOADING DATA The CompuMask is configured with a Data Port located on the inner/right side (Fig. 112a) that enables it to be connected to a PC USB port using the ACI Cable (Fig. 113). A USB Driver is provided on the ACI CD as part of the ACI (AERIS Computer Interface) System. Fig.
The CompuMask checks for the presence of an interface device connection to the Data Port once every second while in Surface Mode. Checks are not made if the Wet Activation contacts are wet. Upon sensing an interface connection, the requesting device (PC) connects to the CompuMask and is prepared for Upload of Settings or Download of Data which are then initiated using the ACI PC program.
MASK PREPARATION AND USE Prior to using the Mask for the first time, thoroughly clean both sides of the Lens with a nonabrasive liquid detergent** or toothpaste to remove any residue (**AERIS recommends McNett brand Sea Buff Cleaner), then rinse thoroughly with fresh water. To prevent fogging during use, rub a no fog solution**, or saliva, on the inner surface of the Mask Lens and Optics while it is still dry (**AERIS recommends McNett brand Sea Gold Anti-Fog Gel), then rinse with water.
CARE AND CLEANING Protect your CompuMask from shock, excessive temperatures, chemical attack, and tampering. Protect the Mask's Lens and Optics against scratches. Aerosols should not be sprayed in the area of the CompuMask. The propellants may chemically attack a components such as the plastic portions and Lens/Optics. Soak and rinse the CompuMask in fresh water at the end of each day of diving, and check to ensure that the areas Fig. 114 - DEPTH SENSOR around the Low Pressure (Depth) Sensor (Fig.
If there is any sign of moisture in the Mask's Optics, DO NOT attempt to use the Mask until it receives proper service. Prior to each dive operation, the Mask should be activated and Battery status, Button operations, Backlight operation, and Set Points verified and/or modified, if required. The Transmitter should be pressurized and transmitted data verified to be properly received by the Mask it is linked to.
To Obtain Service: Take your CompuMask system (Mask and Transmitter) to an Authorized AERIS Dealer. To return your CompuMask to AERIS: Record all dive data in the Log and/or download the data in memory. All data will be erased during factory service. Package it using a protective cushioning material. If shipping to AERIS, obtain an RA (Return Authorization) number by contacting AERIS at 510/346-0010 or send an e-mail to service@diveaeris.com.
BATTERY REPLACEMENT NOTE: The procedures that follow must be closely adhered to. Damage due to improper Battery replacement is not covered by the CompuMask's 2 year warranty. The Battery Compartment(s) should only be opened in a dry and clean environment with extreme care taken to prevent the entrance of moisture or dust.
CompuMask Battery Removal Before opening the Mask's Battery Compartment, inspect the Housing (Mask Frame) to ensure it is not cracked or damaged. Locate the Battery Compartment on the Right Side of the Mask. Remove the 2 Screws that secure the Battery Cover to the Housing by turning them out counter clockwise. Carefully insert the blade of a screwdriver down along the Fig. 115 - BATTERY COVER REMOVAL side of the Cover next to the Depth Sensor (Fig.
If it is necessary to clean the Battery Compartment, flush it and all components with a solution of 50% white vinegar and 50% fresh water. Rinse with fresh water, and allow to dry overnight, or blow dry with a hair dryer set at no heat. Fig. 116 - BATTERY O-RING AND BATTERY INSTALLED Mask Battery Installation Lightly lubricate a new Battery Cover O-ring with silicone grease and place it on the beveled outer edge of the Battery Compartment (Fig. 116). Ensure that it is evenly seated.
Transmitter Battery Removal Before opening the Transmitter's Battery Compartment, inspect the Housing to ensure it is not cracked or damaged. Locate the Battery Cover on the End of the Housing. Apply a coin (not a screwdriver) to the recessed slot of the Cover (Fig. 118) and while exerting slight inward pressure, turn it counter clockwise out of the Housing. Remove the Battery from the Battery Compartment and Fig.
Transmitter Battery Installation Lightly lubricate a new (recommended) Battery Cover O-ring with silicone grease and install it on the Battery Cover, stretching it slightly to work it down over the slotted end of the Cover into the Groove above the Threads (Fig. 119). DO NOT roll the O-ring over the Threads. Fig. 119 - TRANSMITTER O-RING INSTALLATION Battery (+) ( - ) The O-ring must be a genuine AERIS part. Use of any other O-ring may result in an improper seal and leakage.
CompuMask System Battery Test Pressurize the Transmitter to at least 120 PSI (8 BAR) and activate the Mask programmed to link to it. Observe that it performs a full diagnostic and battery check, and enters NOR Surface Mode displaying Tank Pressure and the Link icon. If a Mask or Transmitter Low Battery Condition is indicated, DO NOT use them until a complete evaluation is performed.
ALTITUDE SENSING AND ADJUSTMENT Prior to the first dive of a series of repetitive dives, ALTITUDE (i.e., Ambient Pressure) is measured upon activation and every 15 minutes until a dive is made. > Measurements are taken every 15 minutes during the 24 hour period after surfacing. > Measurements are only taken when the unit is dry. > Two readings are taken, the second reading is taken 5 seconds after the first.
When the Conservative Factor feature is set ON, allowable dive times are calculated based upon the next higher 3,000 foot (915 meter) Altitude. All adjustments for Altitudes greater than 11,000 feet (3,355 meters) are then made to allowable dive times for 14,000 feet (4,270 meters). If the Conservative Factor is set ON while at Sea Level, calculations are based upon an Altitude of 3,001 feet (915 meters). The CompuMask will not function above 14,000 feet (4,270 meters).
