WARNING: Prior to diving with the XR1 Nx, 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 XR1 Nx ! It is extremely important that you read this Operating Manual in sequence and understand it completely before attempting to use the XR1 Nx. It is equally important that you read the AERIS Dive Computer Safety and Reference Manual (Doc. No. 12-7203) provided with your XR1 Nx. It contains information that you must become familiar with prior to diving with your XR1 Nx.
BAR GRAPHS Nitrogen Bar Graph (NIBG) The Nitrogen Bar Graph (Fig. 1a) represents tissue loading of nitrogen, showing your relative no decompression or decompression status. As your depth and elapsed dive time 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.
b a Oxygen Accumulation Bar Graph (O2BG) The O2 Bar Graph (Fig. 2a) represents oxygen loading, showing the maximum of either per dive accumulated oxygen, or 24 hour period accumulated oxygen. As your oxygen exposure (accumulation) increases during the dive, segments will add to the Bar Graph, and as loading decreases, it will begin to recede, indicating that additional Fig. 2 - O2BG and VARI exposure is allowed for that dive and 24 hour period.
ALPHA / NUMERIC DISPLAYS a 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. Depth Displays During a dive, the Current Depth display (Fig. 3a), indicates Fig. 3 - CURRENT DEPTH depths from 0 to 330 FT (99.9 M) in 1 FT (0.1 M) increments.
b Time Displays Time displays are shown in hour:minute format (i.e., 1:16 represents 1 hour and 16 minutes, not 116 minutes!). The colon that separates hours and minutes blinks once per second when the display is indicating real time (e.g., Elapsed Dive Time), and is solid (non-blinking) when times are calculated projections (e.g., Time to Fly). a Fig. 5 - TIME The Main Time display is located in the lower portion of the display (Fig. 5a) and a second time display (Fig.
POWER SUPPLY The XR1 Nx utilizes one (1) type CR 2450 Lithium 3 volt cell that should provide 300 hours of continuous, or 50 activation periods, of operation. If you conduct 1 dive each time the unit is activated, you should obtain approximately 50 dives. a If you conduct 3 dives each time the unit is activated, you should obtain approximately 150 dives. Fig. 7 - BATTERY ICON Battery Indicator A Battery Indicator provides an indication of battery condition.
Upon decreasing to a voltage level that will no longer sustain proper operation, the Indicator will flash 5 times followed by shutdown of the unit. If a Low Battery Condition exists when the unit is activated (by pressing the button), the graphic bAT and the Battery Indicator will appear flashing for 5 seconds followed by shutdown of the unit.
FO2 MODE After Activation, the XR1 Nx will operate as an AIR computer without displaying information associated with oxygen calculations, unless it is set for a percentage of oxygen (FO2) other than AIR (a numerical value between 21 and 50 %). When set for an FO2 value of AIR (Fig. 9), the XR1 Nx will perform calculations the same as if FO2 were set for 21% oxygen, internally accounting for oxygen loading for any subsequent Nitrox dives. However, oxygen related displays, warn- Fig.
FO2 50% DEFAULT If the FO2 Default is set to ON (Fig. 11) and FO2 is set to a value greater than 21%, the FO2 set point value will automatically revert to 50% 10 minutes after that dive. The Maximum Depth that can be achieved with a PO2 of 1.60 ATA will also be displayed. Fig.
WARNING: Prior to diving with the XR1 Nx, 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.
ACTIVATION WARNING: If the unit is activated at elevations higher than 14,000 feet (4,270 meters), it will perform a diagnostic check and immediately shutdown. To Activate the XR1 Nx, press and release the Button. Fig. 13 - DIAGNOSTIC MODE Upon manual activation, the unit will enter Diagnostic Mode (Fig. 13), displaying all segments of the LCD as 8's, followed by dashes (- -), then a countdown from 9 to 0.
Wet Contact Activation (only if Wet Activation is set ON) The XR1 Nx will also automatically activate by Wet Contact. This is accomplished by bridging the gap between contacts located on the Button's stem and back of the case. If no dive is made within 2 hours after initial activation, the unit will automatically deactivate. If the wet contacts are still bridged, the unit will reactivate and display the H2O graphic.
If the wet contacts are bridged, the graphic H2O will appear in place of the dive number 0 (Fig. 16). After the unit is rinsed and dried, 0 will replace H2O. While the Surface Sequence is scrolling press/release the button (< 2 seconds) to access Log Mode. depress the button for 2 seconds to access Set Mode. Fig.

WARNING: Prior to diving with the XR1 Nx, 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.
PRE DIVE PLANNING SEQUENCETM The Pre Dive Planning Sequence (PDPS), which appears after Surface Mode prior to the first dive of a new activation period, provides a sequence of theoretical dive times available for depths ranging from 30 FT (9 M) to 190 FT (57 M) in 10 FT (3 M) increments.
With each Depth displayed by the PDPS, you will see either predicted no decompression limits (NDLs) based upon your previous dive profiles (if calculated to be nitrogen controlled), or predicted oxygen tolerance limits (OTLs) based upon either a single dive exposure or your 24 hour accumulation of oxygen (if calculated to be oxygen controlled). The Maximum Depth allowed for a PO2 level of 1.60 (ATA) for the FO2 setting will also be displayed.
NIBG (NITROGEN BAR GRAPH) (Fig. 28a) a As your Depth and Elapsed Dive Time increase, the NIBG (Nitrogen Bar Graph) will add segments to represent the absorption of nitrogen. While ascending to shallower depths, the number of segments c b Fig. 28 - BAR GRAPHS displayed will begin to recede, offering a graphic representation of your multilevel diving capability. O2BG (OXYGEN ACCUMULATION BAR GRAPH) (Fig.
CONTROL OF DISPLAYS During No Decompression conditions, various displays of information (up to 4) are available. Each provides Depth, Dive Time Remaining, and additional information. The intent of this feature is to allow the diver to select which information is on display at any given time during the dive. The screens can be changed from one display to another as often as desired by pressing and releasing the button momentarily (< 2 seconds).
Press/release the button 2 times (< 2 seconds each time) to change to No Deco Dive Main Display #3. Press/release the button 3 times (< 2 seconds each time) to change to No Deco Dive Main Display #4 (if a Nitrox dive). No Deco Dive Main Display #2 (Fig. 31) Information includes Current Depth, Maximum Depth for that dive (and icon), Elapsed Dive Time (and icon), Dive Time Remaining Fig. 31 - NO DECO MAIN #2 (and Mode icon), and the applicable bar graphs.
No Deco Dive Main Display #4 (Fig. 33) Display #4 will not appear when FO2 is set for AIR. Information includes - Current Depth, current value of PO2 and PO2 graphic, Dive Time Remaining (and Mode icon), and applicable bar graphs. Press/release the button 1 time (< 2 seconds) to change the screen to Main Display #1. No Deco Dive SAFETY STOP (Fig. 34) Fig.
DECOMPRESSION DIVE MODE The XR1 Nx is designed to help you by providing a representation of how close you are to entering decompression. Decompression Dive Mode activates when theoretical No Decompression time/depth limits are exceeded. Upon entering Decompression Mode, the Mode icon will change from No Deco to Deco (Fig. 35). Fig. 35 - ENTRY into DECO The UP Arrow and Deco Bar will flash if you are greater than 10 FT (3 M) deeper than the Required Stop Depth.
The amount of decompression Credit Time that you receive is dependent on Depth, with slightly less Credit given the deeper you are. You should stay slightly deeper (Fig. 36d page 36) than the Required Stop Depth indicated until the next shallower Stop Depth appears. Then, you can slowly ascend to, but not shallower than that indicated ceiling Stop Depth. While in Decompression Mode, Alternate Displays can be accessed that will automatically revert to the Main (Default) Display after 5 seconds.
Deco Dive Alternate Display 1 (Fig. 38) Information includes - Current Depth, Max Depth (and icon), Elapsed Dive Time (and icon), Total Ascent Time (and icon), both Arrows and the Deco Bar, and the applicable bar graphs. Press/release the button 1 time (< 2 seconds) to view Alternate Display 2. Fig. 38 - DECO STOP ALT 1 Press/release the button 2 times (< 2 seconds each time) to view Alternate Display 3 (if a Nitrox dive). Deco Dive Alternate Display 2 (Fig.
VIOLATION MODES While in Violation Modes, the Alternate Displays previously described for Deco can be accessed. Alternate Displays will automatically revert to the Main (Default) Display after 5 seconds unless the button is pressed to view another Alternate Display. Conditional Violation Mode If you ascend shallower (Fig. 41a) than the Required Decompression Ceiling Stop Depth displayed (Fig. 41b), the Down Arrow, Deco Bar, and Total Ascent Time will flash until you descend below the Required Stop Depth.
Delayed Violation Mode #1 (Fig. 42) If you remain above a Required Ceiling Stop Depth for 'more than 5 minutes', the full NIBG and Total Ascent Time will flash until you descend below the Required Stop Depth. This is a continuation of a Conditional Violation. Delayed Violation Mode #2 (Fig. 43) The XR1 Nx cannot calculate decompression times for Stop Fig.
Delayed Violation Mode #3 (Fig. 44) If you descend deeper than 330 FT (99.9 M), the loaded NIBG segments will flash, and the Current Depth and Max Depth displays will only indicate 3 dashes ( - - - ). Upon ascending above 330 FT (99.9 M), the Current Depth display will be restored, however, Max Depth will only display 3 dashes for the remainder of that dive. The Log for that dive will display 3 dashes as the Max Depth achieved. Immediate Violation and Violation Gauge Mode Fig.
The XR1 Nx will also enter an Immediate Violation Mode 5 minutes after reaching the surface from a dive in which a Delayed Violation occurred. On the surface, Violation Gauge Mode displays the Dive Number, Temperature, Time of Day, Surface Interval, and NIBG and O2BG flashing (Fig. 46). It does not provide the FO2, PDPS, or Time to Fly and Desaturate features. The countdown timer that appears when you try to access Time to Fly does not represent 'Time to Fly'.
HIGH PO2 When partial pressure of oxygen (PO2) becomes equal to, or greater than, 1.40 ATA, or 0.20 ATA less than the PO2 Alarm Set Point (a user setting); the current PO2 value, PO2 symbol, O2 segment of the O2 Bar Graph, and UP Arrow will appear on the Main Display as a warning until PO2 decreases. Current Depth and Dive Time Remaining will also be displayed (Fig. 47). If PO2 continues to increase, the value displayed will increase toward a maximum display value of 5.50 ATA in increments of .01 ATA.
HIGH OXYGEN ACCUMULATION The O2 Bar Graph displays either oxygen accumulated during that nitrox dive, or during the repetitive nitrox dives you conduct during that 24 hour period, whichever of the two is greater at that time. The O2 Bar Graph offers you a convenient way to consistently monitor how close you are coming to the limits of oxygen exposure. Use it as a visual reference to place a wider margin of protection between you and the Limits.
WARNING: Prior to diving with the XR1 Nx, 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.
POST DIVE SURFACE MODE When you ascend to 2 FT (0.6 M) or shallower, the XR1 Nx will enter Surface Mode and begin counting Surface Interval. TRANSITION PERIOD The first 10 minutes is, in affect, a Transition Period during which time the following information is displayed (Fig. 50): Fig.
If you descend during the 10 minute Transition Period, time underwater will be considered a continuation of that dive. The time at the surface (if less than 10 minutes) will not be added as Elapsed Dive Time. AFTER THE TRANSITION PERIOD (THE FIRST 2 HOURS) Once 10 minutes have elapsed, the Surface Mode icon and Surface Interval time display colon stop flashing indicating that the Dive and Transition Period are completed, and a subsequent descent will be considered a new dive. Fig.
The Time to Fly counter is provided to assist you with deciding when enough surface time has elapsed to fly (or travel to higher elevations). After a Surface Interval of 12 hours, you may choose to fly (or travel to higher elevations), provided that your dive profile(s) did not enter decompression. If your diving involved decompression or a repetitive multi day profile, it is strongly recommended that you wait a full 24 hours after your last dive to add a greater degree of protection.
Log Mode The XR1 Nx will store up to 12 dives in its Log for viewing. Once the Log is full (12 dives), each subsequent dive will then overwrite the oldest dive stored in the Log. It is therefore suggested that you transfer the Log's data to your log book at the end of each day of diving. Log data will not be lost when the battery is removed/replaced, however, factory service and calibration will delete the data.
While viewing the Preview screen, press/release the button momentarily to view the second screen. Dive Data (the second screen) information includes (Fig. 56) Log Mode icon Maximum Depth - reached during the dive (and icon) Temperature - minimum during the dive (and icon) Surface Interval - prior to that dive (and icon). Fig. 56 - LOG DIVE DATA Elapsed Dive Time (and icon) VARI - showing the maximum ascent rate maintained for 4 consecutive seconds during the dive.
To return to the Surface Sequence at any time while in Log Mode, depress the button for 6 seconds, releasing it when Surface Mode appears. The unit will automatically revert to the Surface Sequence after 2 minutes if the button is not pressed to view another Log Screen. AFTER THE FIRST 2 HOURS Two hours after the last dive, the Surface Sequence will no longer be displayed. The Time to Fly and Desat countdown screens (Fig.
WET CONTACTS If the graphic H2O appears during the Surface Mode (Fig. 60), Fly Mode (Fig. 61), or Desaturation Mode, it is an indication that the wet activation contacts are bridged (still wet) and the unit must be rinsed in fresh water and thoroughly dried. The contacts are located in the button stem and back of the case. Fig. 60 - SURFACE MODE (unit wet) Once the unit is dry, the graphic H2O will disappear from the display.
RESET (CLEAR) FEATURE The XR1 Nx is configured with a RESET feature that allows data to be cleared, including Nitrogen and Oxygen calculations and Log Mode entries. WARNING: Reset after a dive and subsequent use for a repetitive dive conducted by the same diver could result in serious injury or death. RESET PROCEDURE While the Surface Sequence is scrolling, press/release the button to access the Log Mode displaying the first screen (Dive Preview/ Identifier) of the most recent dive.
UNEXPECTED LOSS OF DISPLAYED INFORMATION If your XR1 Nx 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 Accumulation Limits, and a critical reason to avoid entering Decompression.
WARNING: Prior to diving with the XR1 Nx, 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.
CARE AND CLEANING Protect your XR1 Nx from shock, excessive temperatures, chemical attack, and tampering. Protect the lens against scratches with a transparent Instrument Lens Protector. Small scratches will naturally disappear underwater. Soak and rinse the XR1 Nx in fresh water at the end of each day of diving, and check to ensure that the areas around the low pressure (depth) sensor (Fig. 63a) and button are free of debris or obstructions.
To Obtain Service Take your XR1 Nx to an Authorized AERIS Dealer or send it to AERIS. To return your XR1 Nx to AERIS: Record all dive data in the Log. All data will be erased when it receives factory service. Package it using a protective cushioning material. Include a legible note stating specific reason for return, your name, address, daytime phone number, serial number, and a copy of your original sales receipt and Warranty Registration Card.
MODULE REMOVAL FROM BOOT If the Module is in a Console, bend the rubber Console Boot back to expose the edge of the Module. If the Boot is flexible enough to permit, you may bend it back far enough to scoop the Module out with your finger. Otherwise, it may be necessary to insert a blunt screwdriver until the tip rests just underneath the Module. DO NOT pry the Module from the Console! Slowly increase the pressure under the Module by releasing the tension on the rubber Boot.
Battery Hatch Removal Locate the Battery Compartment on the back of the Module. While applying steady inward pressure on the center of the Battery Hatch, rotate the Hatch Retaining Ring 10 degrees clockwise using a flat blade screwdriver (Fig. 64) or a Battery Hatch Tool. Lift the Hatch Ring up and away from the Housing, or turn the Module over to allow the Ring to drop out into your hand. Remove the Battery Hatch. 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. 66 -INSERTING BATTERY WARNING: If damage or corrosion is found, return your XR1 Nx to an Authorized AERIS Dealer, and DO NOT attempt to use it until it has received factory prescribed service.
Lightly lubricate the new Hatch O-ring with silicone grease and place it on the inner rim of the Battery Hatch (Fig. 68). Ensure that it is evenly seated. Slide the Hatch Retaining Ring, top portion first (small opening), onto your thumb. Carefully place the Battery Hatch (with O-ring) into position on the rim of the Battery Compartment, then press it Fig. 68 - O-RING ORIENTATION evenly and completely down into place with your same thumb.
Inspection Activate the unit and watch carefully as it performs a full diagnostic and battery check, and enters Surface Mode. Observe the LCD display to ensure it is consistently clear and sharp in contrast throughout the screen. WARNING: If there are any portions of the display missing or appearing dim, or if a Low Battery condition is indicated, return your XR1 Nx to an Authorized AERIS Dealer for a complete evaluation before attempting to use it.
ALTITUDE COMPENSATION 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. The XR1 Nx automatically compensates for decreased ambient pressures for Altitudes between 2,000 (610 meters) and 14,000 feet (4,270 meters).
